I finally got my FI catback exhaust and lower downpipe installed yesterday (loving it so far!). However, I've noticed when going over certain bumps there seems to be some rattling going on in the back. Has anyone else experienced this or know what might be causing it? I tried googling it some...

Hi I am selling my exhaust i had it on the car for about 2 years, 15k miles on it I just sold my car and this was the best thing Ive done to it. I am asking for $900 for local pick up in NYC. I had it on my 2018 q60 coupe AWD 3.0T

I'm looking to buy Fast Intentions cat back exhaust, preferably with the 14" resonator, for 2017 Q60. Unless in the northeast, would have to be willing to ship. Hit me up with anything you got! Thanks,

I've searched and looked around for this topic but I haven't seen anyone compare the two. Lots of great reviews for both of these pieces. However, I was wondering: How much better are FI's catted downpipes compared to Z1's? Z1 Catted Downpipes: $898 FI Catted Downpipes: $1695 Does come down...

Recently we met up with Davis and his bagged Q60 coupe. His car was one of the first to receive our 10" Sport mufflers; and to think its now our most popular selling options.
