I was looking around the forum, seeing what exhaust i should get, dont really want a custom job, so i was looking around and i came across BigAl_UK's RS*R on his 6th gen, then i thought isnt this only for 7th gens? so i was wondering how was he able to fit it in? and if 5th gen or 7th gen exhausts can fit on a 6th gen? just some thoughts in my head, thanks in advance.

RS*R made an exhaust for the 6th gens at one point. i donno if they still do. the only RS*R dealer i knew, stopped being a dealer like a year ago. But 7th gens and and 5th gen exhausts wont work without modifying the. Best bet is either go with a custom made exhaust with a good muffler, or go with a pre-made system for our cars like either a kakimoto, or Greddy SP2.
