Sooooooo......

Where's that dyno sheet? I want to see what 3'' piping does.

Close to 30hp and 30 tq gains bolt on without tune. Not bad.

I think that 30/30 gain is with their scorcher tune, no? I can't imaging the exhaust alone is going to add 30hp....would it?

I like it. Best of what's available at the moment in my opinion.

AFE sounds the best so far IMO

No way a catback is going to net those gains by itself.

Most catbacks on turbos aren't going to net any gain. If you don't remove the restriction at the downpipe, you won't really see any benefit other than sound.

And if you remove the cat you remove the warranty... I'm not confident in doing that quite yet.

You don't need to remove the cats. Most newer OEM cats flow just fine. The issue is the downpipe from the turbos to the cats. Exhaust can only flow as good as its weakest link. Putting a bigger exhaust on from the cats back won't offer any gains since the engine can not push the exhaust through the downpipes any faster. If you want to just change the sound (which is really all a cat back will do), you can change the muffler and get the same results.

Makes sense... so do you think removing the down pipes would remove the warranty? I was planning on opening that up.

Yeah you're right. I misread. The gains look to be from their tuner.
