Right now I have catless downpipes + single mid-pipe ... volume is a bit louder than I want and would like to reduce/eliminate the smell, but curious how the catted downpipes compare against catless from a power/hp standpoint.

I'm sure they produce less power, but how much and any noticeable spool/turbo response differences?

Has anyone tested this and will it help with smell/volume reduction?

Thanks!
