    Just ordered full American Racing S65 V8 exhaust including headers

    Well, since I sold my custom exhaust when going turbo that left me in a bit of a problem as we're going back to a stock internal supercharged setup.

    The solution? ARH or American Racing Headers full system:

    I'm particularly interested in the headers:

    Went catless with no resonators. We'll see what the car sounds like and dynos maybe as early as this week.

    Go big or go home, right?

    I've heard good things. However, I also heard you lose about 1lb or so of boost so you need to pulley up and tune!

    It's not that you are losing boost it is that you are gaining efficiency. More power with less boost is a good thing.

    i have a friend with a vf 650 kit and those headers and the car sounds like an old f1 car, in a very good way.

    Any back story to this decision? My guess is you are done with the Gintani BS, wanted a reliable car...maybe for resale.

    It's not Gintani's BS it's just the S65 block.

    It was their suggestion after trying a multitude of setups for various people.

    Part of me wants to do a billet block just to show people what the platform can really do. I might when I have a spare $25k laying around.

    Should have done it from the beginning instead of trying to make that block work.

    Have you tried not sleeving the block? With sleeving you might get stronger cylinder walls but also you increase flexing since the block is no longer a one-piece structure.

    That's why it's a stock motor. No sleeves.

    Sleeves are bad, they sacrifice the strength of the block. Just have Dinan bore/hone it if you want to oversize a bit.

    ARH are good and should sound great and pick up some good power and efficiency (less heat).

    You are absolutely correct, headers and ported head makes less boost for a given pulley but its actually moving more mass air flow because less temperature rise from the higher boost.

    The removed material compromises the block.

    Is he/you saying the S65 specifically or sleeving as a process in whole?

    What size primaries and collector? 1 5/8? 1 3/4? No ceramic? Interesting to see them in the raw. I've heard great things 30rwhp on those headers. I'll be interested how much boost you lose. I've read about 1lb? Power is the same but then you can add it back in. Great mod just wish they weren't so pricey for just hearders. $#@! small block shimmy headers are what 300 bucks? ceramic coated? Economies of scale...

    The factory headers are pretty good. Improving on them is much harder than your average domestic.

    I honestly have no idea.

    per the website 1 3/4. They claim "real gains of 40 RWHP and 35 RWTQ (before tuning) on a bone stock M3" Shizam.
