        Love Weistec products. Those guys know what they are doing for sure. If I had an AMG, I would be hard pressed to look anywhere else for products.

        The information in the article is well done. And the pictures, in order is great. Excellent layout Sticky. Made in Romania I take it? They appear to well conceived, engineered and built components. Quality does not come cheap, as I can see from the pricing.

        Boutique European manufacturers typically charge serious money, but quality is there.

        Their E63 that they has these upgrades mounted on is an absolute monster, at the 1/2 mile airstrip event it ran neck and neck if not slightly quicker than my Weistec stage 3 C BS in the 1/4 mile, my C did not pull it until the big end. I was blown away when I saw getting pulled on the front half by a big heavy four door sedan.

        Any idea how much power and torque can be expected from an E63 on 91 octane with the downpipes and a tune?

        look at the dynosheet (which is in standard STD correction) and ask yourself why isnt there a torque curve?...

        The guys at AMS stated they couldn't get a clean tach signal which is not uncommon on big hp turbo cars.
        Not sure why you can't understand that, which is probably why you got neg repped. AMS has a lot of experience with big hp turbo cars, no reason why they can't do the same thing with the M157.

        You'r right my friend, it includes a little bit of straight pipe. Come on, 5K.

        My local shop that does ST, could do it custom for about $1K.

        Yes, it would not be double coated, etc, etc. But we are talking exhaust piping here.

        Again, Weistec, you do GREAT work!!! And thanks for the snail upgrade!!!

        But give us little guys a break on the pricing of exhaust pipeClick here to enlarge

        I don't think the price is due to the materials alone but the engineering that went into it. If you ask them I'm sure you will have a better understanding. What I was told directly is that it was over 6 months work and nobody else has a solution like this.

        And there you have it! Monopoly is rarely good for the consumer.

        At least they made it beautiful - and for the money, they should have.

        It would be better to have nothing? Other companies need to spend the money and do the engineering themselves. They deserve to recoup their cost and make money. Nobody is stopping competitors...
