Pro Circuit T4 Exhaust

Recommended Posts

I put the T4 exhaust on my 426 three weeks ago because it had a removable (takes three minutes) cone-type screen spark arrestor. The pipe is a three piece unit and fits perfectly.

Yes, it is louder than stock, even with the screen in and it makes a bit more power and also seems to allow the engine to rev further. The core is 2" in diameter (much larger than stock) and Pro-Circuit says that a quiet core may be available soon.

I only run the bike half throttle anyway, so I didn't need more power and possibly someone who can actually use the power would be better suited to evaluate the output.

It seems to start easier, but that may be because I'm getting used to the four stroke.
