I decided to order the SS exhaus for my '97 M3, any pros or cons? i heard the note of the SS on 2.8 Z3 at MZ3net, and loved it, im sure the M3 will be louder since it's 50 more HP. I couldn't tell much from the M Roadster since it has quad exhausts, which sound louder anyways. How much for installation? and how long?
Also, would you guys recommend the Dinan cold air intake with carbon fiber? i'm offered a new one for $350, what do you guys think? good deal? good combo with the exhaust? too loud? how much tourque and HP gain? any problems with the dinan intake?
Any more info would be appreciated!
