The smell is totally gone and its quieter. but it's not as responsive as before. I'm thinking to have catted downpipe and swap back to my old midpipe. any thought?
Really, the smell isnt any different for me
Havig said that maybe being a N54 and yours an N55 is the difference?
Hmm I cant really comment on going with a catted dp setup on a n54 as i havent any experience with that setup, but I think if I was in your situation i may possibly leave the setup as is.
The difference is that n54 midpipe has two small cats whereas n55 is a straight pipe. that eliminates most of smell even with cattless dp . that is also why i feel throttle is not as responsive as before. But overall I'm happy with my current setup. Because I'm more concern the smell.
Ps. Now I have a spare n55 straight midpipe.
