Would i be able to run an after market down pipe on to the stock exhuast ? Would the stock cat back negate any gains that i would gain from the downpipe ? How easy is the install or swap (removing AM downpipe and putting back in stock) if i have to take it to the dealer?

I'm running a depo catless dp with my stock exhaust. I do have a resonator delete as well. I've read that aftermarket exhaust doesn't do much for this car. So with that being said I think I'll gain power once I tune it . If you do lose power of think it negligible. Once I tune it ill post dyno results.

Thanks, sounds pretty raw idling, i was dissappointed with my res delete, was hoping for more sound out of it.
It's lower once it warms up. At operating temperature you can barely hear the humming. I had the same reaction after my resonator delete too, but after a while it got a little louder and a little more aggressive.

After hearing a all the different exhaust sounds I am not sure if I'll ever find one I like. Never felt like that with my V8s.
