Hey,
03 F4i Stock now, but going K&N filter, power Commander III, probably down one tooth front and up 2 rear...

Looking at Yosh Tri Oval and Other silimiar pipes. (Like everyone else) I want much louder than stock but not quite D&D, looking for nice clean LOUD sound. Wondering about going slipon or full system. How tough are the full systems to install? And will the sound/power be worth the extra money and time? Any Advice? Thanks Guys.

Also looking at sliders... I keep reading that you have to madify the fairings to install. How Much? and Is that pretty easy?

 

putting a full system on there won't help all that much, but if you are putting a power commander on there anyway, go with a full system, all i have is a akropovic slip on and it works great....just my .02

 

get a slip on. you dont need the full system. been there done that custom mapped with pc and everything. end result? lost a lot of cash [:'(]
