Re: Performance parts
Depends on whether you want to go single or duel exhaust. Benefits and negatives have been listed here many times before, I have a K & N filter with Genie Extractors and single 3" with a straight through muffler and then a resonator with twin outlets. Sounds very nice both idling and screaming (well at 4000rpm) I also changed the T/B but you already have the 70mm one, if you do the exhaust you should be pretty well moving, you then can do cams chips and porting!!!! All fairly expensive with no visual or audiable difference (sorry you may hear a difference with the cam). Then stroke it or charge it or maybe turbo it would be something very different.
