2 of the quietest, I have found is FMF and Leo Vince. The FMF is alot cheaper.I want more power on my 700xx but here aftermarket exhaust are illegal, wondering if I can just replace the stock header and air filter ?
If not then is there anything stealthy and that wouldn't be too loud that could give me a bit of hp more. Thanks.
Thats all I am running and it does help out .IDK about replacing the header and using factory pipe? But have herd just adding a programer and a filter will help a little.
