Wow, cheers for all the responses guys!
Mine is a 55 plate UK 350z, which I *think* means I don't have the rev-up later engine in.
Out of interest, and this will probably sound stupid, what does "or go fi " mean?
The responses were prity much what I expected. Question I guess is do I go for a true dual exhaust or a full exhaust and new Y-Pipe! (Is there much difference between the 2?) This only thing which concerned me with new cats etc was:
1/ Passing an MOT. I don't really want to have to swap things out for my MOT. Ive had a car previously which was a nightmare to MOT and know how much of a pain it can be. Would one of the options listed above still be fine for that? Do you guys think that it would be a noticeable difference to fit?
2/ Sound. Whilst I do want to squeeze a few extra horses out of the car, and a bit of extra grunt would be nice, I don't want it to sound like a rocket ship when i go down the road!! Am I being over cautious?
Cheers in advance!
