i just hope the dealer fixes my car and it's done right . then i have to wait a few days or to be safe a week to make sure the code doesn't come back.
lol....

I can see I am gonna have a problem with that arrangement

you need to take yours to a dyno...run it stock and then add the program to see what the difference is.

Sound in the cabin is ok. Honestly I think the cat back only with the factory downpipe will be pretty mellow.

With the 2 together it's deffinatley louder inside. I wouldn't call it a drone but due to the SUV characteristics it's very hard to avoid.

We tried a 5" round (3" core) muffler yesterday and while it did drop it 3db it made the frequency worse.(I removed it immediatley)

Gotta keep in mind that you're not expecting 40+ hp from "exhaust alone." It's... "exhaust which frees up the turbine to spin" that I would have expected more. Remember... the engine gets "bigger" at the top end of the RPM band in a way that NA motors do not.

I've got a much less expensive suggestion... since I've got the tune, people can pitch in and send ME the exhaust.

Maybe I missed it, but what's the price for this?? Are there 2 different part #'s for the cat-back vs turbo-back exhaust??

I think they have considered doing the non catted DP but until there is tuning readily avaliable you will have a problem with check engine lights.
No check engine lights if you erase the code with hp tuners. Thats what i did. I have a catless downpipe. I went through ADM and paid $599 for a full 3" turboback
