elijah354524 Posted April 5, 2010 Can any one tell me the pros and cons of the slip on exhaust or full system? How much power will I gain...... Share this post Link to post Share on other sites
SheWolf Posted April 5, 2010 Well, guess it depends on who you ask. I know someone who's got the full FMF system (Q4 & PB header)and he feels there isn't much of a difference. That's why I never bothered spending the extra $200 on the header. I've also heard from others that they feel they've lost a bit of mid range with a header. I really don't think you're going to gain any significant hp from a header vs just a pipe. Your hp gains will be from a mix of exhaust system, airbox mods and fuel programming, not just the exhaust alone. Share this post Link to post Share on other sites

HK416 Posted April 7, 2010 In that case I'd say slip on pipe and power commander will give you a couple ponies. Haven't played with the different PCIII settings on mine yet. Just using what they reccomended for K&N filter and slip on. I will soon. Looking forward to NOT ripping the carb out and rejetting over and over just to try it out. I asked because my DRZ responed better to a header and pipe than slip on alone. I was able to go with a slightly larger main jet and get less lag between 1/2 and WOT.
