[livetoridea400]

i am thinking aboout byeing a pro circuit t4 i want to know if it is a good idea or not. and how do they sound.....

[coryatver]

I liked mine a lot. They sound nice and give a lot more power and not a lot of people have them

[Rafikie]

I had one on my 400ex and loved it. then I chopped 4" off the end and polished the hell out of it.:devil: still miss that pipe

[EvilMaximus]

[Rafikie]

I used stocker

[fast_enough]

I had one on my 400ex and my KFX they both sounded great and were all around great pipes

I had one on my 400ex with a ported stock header and loved it, sound and power.

[livetoridea400]

do you have to rejet the four wheeler?

I have a used one with a dent on the bottom. I just polished the **** out of it so the shine is good. This thing sounds sweet and I used the stock head pipe. I went to a full lrd so I don't need this. Will take 150.00 shipped for it.

Yea i used to use the T4, excellent pipe all around. I just had a slip on with stock header, but i was very impressed with the power and nice sound. Looking to get an HMF now though...

[livetoridea400]

do you need to put a jet kit in it or can you run it with the stock jet kit.
