- Cat back exhaust system (with secondary cats removed or replaced with high flow cats)

As previously mentioned, the biggest restriction is keeping the stock downpipes. If you keep stock DP no matter what you have after is not enough.

Stage 2 will at minimum require catless DP, Intercooler, and intake.

ANybody know what kind of performance improvements are expected with Cobb Stage 2 over Cobb Stage 1? (Sorry, don't mean to hijack the thread.)

You'll never see Rob's power on an off the shelf version. It will always be less because of safety concerns. ATR is the first opportunity to get a perfect COBB tune for your individual car.

Interesting. I can't wait to head back to the dyno after stage 2 is released.

As expected. ATP first?

My whole exhaust system from the turbos to the mufflers is stock, except i have REMOVED all 4 cats and welded straight pipes instead (same size diameter as stock pipes). I have no problems with any inspections. So would you think i can safely run stage 2?

Robb? Jeff? Anyone?

Thanks

Should be ok. Remember guys, stage 2 is a map so you can log it to see if its adequate for your mods. If its too aggressive the logs will show and you can go back to stage 1.

etc335i · 08-30-2011, 03:14 AM
