Nah, the "headers" blow into the turbos. The downpipes have a little cat and attach to the turbo and drop down and attach to the rest of the exhaust under the car. I'll be interested to hear what the feedback is on the AR ones...

Thanks

Another question: Would a race cat make more (dirtier) emissions than the stock cat? Or is the chemical reaction the same on all kind of catalysators. Race cats just have a better flow with same reduction in emissions as a stock cat?

Wishlist: FMIC. Better oilcoler. A little bit more sound when floring it but not so it get tireing on longer trips. Quieter tires. Less understeer. Will not drop it!
