love it on here. loads of people with loads of stories. i'm wondering nosing around sites looking for the big end bearings on my s40 and i see loads of various bolt on bits to go faater, louder or smoother. make me think what does and doesn't work. what's the best for getting the perfect power band, or exhaust note, or most confident handling. so please say what worked and what didn't. at least i won't make the same mistakes.

I know you will find dissenting opinions on Evolve, but I personally have not had an issue with them. Quality parts, and they look great. The exhaust sounds great too. Looks like they plan on coming out with 00-04 S40 parts...
