This is what I am looking for: I ride trails and small self made tracks, MX , TT , and Drag. My bike is all stock and I am looking for maybe 5 hp at the max. What slip-On is going to be the best, If I go loud, I'm going real loud. I was looking at the procircuit T4, FMF Titanium, powercore, WB E-series and R4, HMF, LRD, Graydon, and DR fat boy 4. i want to go with sprockets and rev box also maybe...would this help if so what to buy... I need my bike as quick as possible in 100 yards dont care too much about top-end as long as i can do over 60mph! need power for hills, tight trails, and extra people i carey on my 400ex. How can i make mine go faster for a low price, i have no money, if you have good products u want to sell...go ahead and list them.

You may have to search a bit but I remember a thread here that linked to a online hp comparison of slipons and full systems.

It didnt compare all pipes mostly just one setup from each manufacturer.

I think somebody scanned it out of a recent dirt wheels or some other mag.

but im sure if you search the performance forum for exhaust shootout or something like that you can find the link.

That's what I went with, I'm very happy with the sound and low-mid end power gains. It was $219 I think too. You're probably going to have to get a different jet too, if you decide to go with HMF.

Slap a 175 main jet and a 42 pilot in your carb. and you're set.

I highly recommend a WB e-series slip on, I have it on my 416 and it performs great. Look at my sig to see what else I have done.:macho
