Your Thoughts on The FMF Titanium4 Full System?

5 posts in this topic

I can get one for $300....do they make a spark arrestor for it?...Is it too loud?...How much power gain? Im running a stock header and a WB E-Series silencer right now on my '01 426. Any rejetting required with it?

Thanks!

I noticed a major gain in HP :) Mostly because I was running an FMF Q series prior. I went up one size on my main and tweeked the air screw a little bit.

FMF does make a spark arrestor for it ($50 later) but I recomend going to mcmaster.com and ordering some small SS wire mesh ($7.50) part # 9238T531 and use the end cap they give you. I don't care about the added noise, I'm not paying attention to that, I'm more worried about crashing.

I like mine a lot. It might not be a 96db pipe, but I'm pretty sure it's under 100. It's certainly way quieter than the R4 on my kid's 250F.

Mine has the Power Bomb header. With the stock system, it had a kind of "hit" in the middle of the power curve. With the FMF system, it pulls hard from the bottom clear to the rev limit. I can't really feel a difference in peak power, although dyno charts show a gain of about 1. What I do feel is the power curve is a lot flatter; more power above and below peak.

If you can get one for $300, get it. :)
