N55 with catless DPs and catted mids (from N54)

Hey there,

This might be a long shot, but are there any N55 owners with a catless DP but catted midpipes from an N54 in the GTA? I ask because I recently installed catless DPs on my N55 and the smell is really bothering me. If possible, I would like to meet up and see what your car smells like. Wondering if installing catted mids from an N54 can eliminate the smell. Thanks!

Why not just throw on 2 metal spun high flow cats?

Should get rid of most of the smell and keep the benefits of better flow than the bulky oem cats.

I used the flow master 2.5inch cats to get rid of that and replaced my secondaries with them.

zort Why did you switch to Flowmaster cats instead of retaining the OE secondary cats?

I went for a catted dp from ar for exactly that reason and couldn't be happier rarely ever catch a whiff and they sound amazing with my pe exhaust . Give it some time if it really continues to bother you than make the switch you wont be disappointed. the cats incorporated into the ar design are magnaflows 200 cel. I believe you can also purchase them separately for around $100 ea.
