There is a slight sound difference but I personally can't smell a difference with my ******* ***.

I've had ******* ********* in other cars without secondary cats and the smell is terrible.

I can smell a difference, but its not horrible. No one else has ever noticed it. As long as your state doesn't have a sniffer for emissions, it'll be OK.

My car has cpe ******* and is a lot louder! Stock after that. I get comments on it quite a bit.

I'm actually really interested in this as well.

I'd like to shop for a catted ********* that have the least NVH/smell. Do any of the catted dp brands offer similar to stock performance in that regards? I'm kind of picky when it comes to NVH.

More than even power I'd like quicker spool up time. If catted *** had zero increase in NVH/smell and gained about 10whp and made turbos spool quicker I'd be very interested.

I tend to have a no side-grade only upgrade policy :D
