I am getting ready to order the Cobb stage3 package, but I was wondering if it is ok to run stage3 with the stock catback exhaust? I am worried about unwanted police attention. So my setup would be Cobb intake, Cobb turbo inlet, Cobb ECBS, Cobb downpipe, Cobb testpipe, stock catback, Cobb accessport with off the shelf maps. Have you had a chance to do any testing of your stage3 maps with the stock catback?

 

Stock cat back is super restrictive. Get rid of it.! Don't be scurred lol if you want aa quiet exhausttry the t1r sparrow. I have it in mine. It's quiet at idle, my cabin doesn't drone, but you can definitely hear it when I get on it and it doesn't sound like a bloody cow screaming at the top of its lungs either (I know... That was a weird analogy) lol

 

Yeah ditch the catback get a cobb like I have or go for something else, but def get one

 

Just go with the Cobb catback, you wont have any issues with extra attention. I forget I have an aftermarket catback until I really get on it. I almost with it were a little more aggressive.

 

Yeah all those mods with a stock catback doesn't make too much sense from a performance standpoint.
