    • Evolve E9X M3 S65 V8 Primary Cat Delete/ Test Pipes and Stage 2 ECU Tune Package $1349 - Dynograph

      This is a follow up to a previous post from Evolve Automotive which showed how large of a point of restriction the primary catalytic converters are for the E9X M3 S65 V8. The primary cat delete alone with the Evolve test pipes yielded a gain of 19 horsepower at the wheels. Now below you will see dyno results for the Evolve test pipes combined with an Evolve Automotive Stage 2 tune. What is the result? 34 wheel horsepower with the Stage 2 tune providing an additional 17 wheel horsepower on top of the cat delete and obviously taking the test pipes into account with the tune.

      This makes for a very cost effective package for upgrading an E9X M3. Further details along with dyno graphs and pictures from Evolve Automotive below:

      It is well known that the Primary cats are a major restriction point on the E9X M3. There are a number of solutions on the market including a full X Pipe which removes the primary cats (our one also has 200 cell secondary cats and resonators) or Primary Cat Delete/Test Pipes.

      X Pipes designed to appeal to those who want a bolt on solution that can be easily reversed when required. This also gives the user the option to sell the X Pipe on should they remove it.

      Primary Cat Delete/Test Pipes are designed for those who do not want to go the full X Pipe route and are happy to modify their existing X Pipe.

      Our Primary Cat Delete/Test Pipes are the first in the market to use a slip on and clamp solution. This provides a solid/tight fit without the need for welding.




      This package teams these primary cat delete / test pipes with the well regarded Evolve Stage 2 ECU Tune with option of free Servotronic tuning. Feature coding is available at a flat rate of $200 for unlimited choice of the options we offer.

        Is it safe to say this car will make in the 380-390 area with a Macht Snell intake and pullies?

        Thought i'd give a quick update for everyone now that I've put in the evolve stage 2 tune and primary cat delete pipes. Top line - i'm very happy i did it, and well worth the $1800 or so - total price derived in shop time plus the $1349 shipped price from Evolve. Sal gave me a factory tune to install first with the pipes, and then his tuned file to put in after i'd run it clean for some miles on factory + pipes. The pipes and cable shipped out very quickly, i had the whole mess from Evolve in less than 3 days. It was exciting to track the shipments from across the pond, shipped by "TNT". I read my file with the cable the same night, got it back to Sal, who got me my new files overnight. The software and OBDII cable work perfectly without issue - its a slam dunk to get these, so you can read and load tunes, and clear your own codes. I got cold start delete, top speed limiter, rev limiter, fuel mix - had to keep 91 octane since i'm in California, servotronic tune, and DCT upgrade. One thing i'm worried about is that the car won't be adaptive to higher octane mixes i'll get at the track. I need to find out as i have a track day coming up. I also ordered the "cabin amenities" tune, which is $200 extra and has a long list of very cool software changes to the interior controls (find list on evolve website). Anyway, the DCT upgrade and "cabin amenities" haven't arrived yet, Evolve is working out some kinks with registration issues with DCT, and i haven't heard word on the "hack tune" yet either, but after the world class turnaround on the pipes, cable and tunes, i'm not worried, these guys are fantastic, and i thoroughly enjoyed my conversation with Sal, he is a real enthusiast and M3 specialist. He has one as a daily driver as well!
        Anyway, onto install - during the install of the pipes, I had some issues fitting the sleeve on the left side. The right side went in fairly well, that side is round, unlike the left, which has some bends and isn't perfectly circular. We ended up welding a cut section from some scrap pipe we had in the garage to match up the left side. I'm planning to go back and cut the sleeves, and weld in chop slices in their place, to get a nice fit - i sprung a couple leaks at the sleeves. The sleeves have 1" groove cuts at the ends, which i believe is a mistake to manufacture. These cuts didn't help me with fitment, but they did allow leaks. These primary cat delete pipes would be better sold with a sleeveless, "weld-only" option. This would have saved some hours on the lift. I had 3 1/2 hours in the air. My advice for fitment of these "primary delete pipes", if you purchase them, is to do the cutting and install in two passes. First make cuts to the stock pipes right at the welds of the cats, which will probably leave you a little long. Slip on the sleeves, and attach the full exhaust back to the car, and measure how much you need to trim. Take them back down, make your final cuts, then re-attached sleeves. I had a really hard time attaching the center bracket, where the sleeves come fitted with their own clamps. My mechanic tried to convince me to toss the center bracket, but i worried about torquing force on the pipes , especially on hills. So we retrofitted some standard bolts from an old ford, piled on the washers, and torqued on the bolts. We stripped a bolt and had to refit it, all in all, the center bracket cost me another hour or more on the lift, so its something to consider, if the engineers say it can be tossed, then toss it. Since i didn't know for sure, i knew that keeping it was safer. Its holding up so far, so i think it was the right move.
        since the pipe fitment was a bit of a bear, I've worried maybe the full exhaust option would have been a better option (i was being cheap, saving the $1600), and i was definitely happy to hear some opinions on this thread about liking the car better with just cat deletes. I agree that the volume output has been just what i was after, the sound is not changed much, and is exactly what i wanted, its got a better "race car" sound at high revs, and at low revs, hardly a change. However, i wouldn't talk anyone out of total exhaust replacement. I need to track down some stock pipes now for my next smog in two years, and i spent extra hours in the shop, so really, i'm guessing the actual difference in price ends up closer to $1100-$1200 (instead of $1600), going with the new exhaust stage two tune package for $3000 - once you factor in shop time and stock pipe purchase (for smogs).
        Ok, now for the quick review on performance. Noticeable gains! There is more torque here. Its noticeable especially in first taking U-turns - i can spin the back wheels without effort, that wasn't as easy before. I ran several pulls on the freeway. The best part was free revving up to 8700 RPM, with full power all the way to the rev limiter. When i put the JB and intake cones on my 335i, it was life changing. The Evolve tune for the S65 M3 is better stated as "refinement". Let's take this conclusion with a grain of salt - I don't even have a half tank of gas burned yet, so maybe the adaptive software has some catching up to do. Also, i haven't gotten my BCI air filter i ordered yet. But I'm wondering if anyone has an opinion about changing plugs or coils. I'm getting no errors, but i have 60k on the car (just bought it, was a female driven freeway commuter, still has marks in the backseat leather from the babyseat!). So, opinions on changing plugs? My mechanic says i'm throwing away $300, but Sal @ evolve gave me a lecture on making sure the plugs/coils/02 sensors are shipshape. Any advice on things i should change to realize maximum HP gains, let em rip! (except quoting me on the e600 supercharger, @$16k installed, that savings fund is going to take a few years). Oh and hopefully i'm not giving away any Evolve secrets, but Sal mentioned their working on an intermediate supercharger option more in the $8-9k region as a halfway point, hopefully better afforded for us guys with mortgages and 529 plans to fund.

        My eyes hurt! But nice review.... the news about a cheaper SC option is great. I hope Sal makes it so you can upgrade, that would be perfect!

        They could really put a hurting on the market if you could start with a non intercooled option, upgrade down the road with the cooling package, tune, etc.. I don't know if the blower could be used for both a low hp non intercooled and then for the current stg 1.... I would buy it now if it existed.

        "hack tune".... sounds interesting! Wanting more info on this one. Maybe he can make the initial cold-start rev more aggressive? I hate the OEM's initial cold-start rev where it only goes to approx 1,000rpm (seems lazy to me, but I understand the reasons why), my 335i would initially rev to 1,500-1,800 upon start up and, my G35 would initially rev to 2,000 upon start-up, both of which gave a nice "bark" when you turn on the car, and then quickly settled into that normal 1,200rpm "cold-start" rev range.

        I'm still waiting on my DCT tune too, the cable I received unfortunately couldn't be coded or updated with the HEX codes, but Sal explained the process in detail, and will be shipping out a new cable to me shortly. I absolutely love the tune, it feels completely stock in driving refinement, only more "pushy" throughout the rev range; it makes you forget the S65's flat torque output. It seemed to amplify that exotic high pitched exhaust howl-zing between 3,400-3,700rpm as well, which sounds great in combination with my test pipes.

        As much as I love the tune, to me it doesn't compare to the Servo mapping, that thing completely changed the character of how the car drives. The OEM steering gear is wonderful, nice feedback, quick ratio, and solid in response, but the lack of weight ruins the overall experience, as other magazine reviews have stated. The Servo mapping made the steering assist smoother in operation, the steering weight is substantially heavier (the original file received was great, but I requested something heavier, which Sal was happy to map & try out), which gave the car a new sense of solidity, and now requires virtually zero steering corrections (even when it's windy) as it drives down the road; the car feels like it's sucked to the road, feels like the car weighs 6,000lbs when on-center, but smooth in assistance off-center to where it feels somewhat livelier with better feedback, and everyone who's driven my M3 in comparision to their M3 were in amazement of how much better the steering weight is and how more substantial the feedback is, not exaggerating in anyway shape or form. It also got rid of the delayed assistance compared to the OEM M-dynamic mode, where sometimes you'll get zero assistance, and then magically a split second later, you get full assistance, which made the steering wheel awkward.

        This definitely interests me. Good details.
