Looked at a lot of pipes but finally chose this one for my kx250f buying this pipe along with rejeting the carb gave it a big power boost

Changed the power delivery and the bike feels great. Way more aggressive than your stock exhaust. Pricey upgrade but worth it

Awesome Product

The install was so easy, they give you everything you need. I love the look and sound of it. The performance is so noticable. Great exhaust!!!

Must buy

This pipe is awsome!!!! My stock header was melting one of my hoses and this one doesnt even come close to touching it!!!! I ride an 07 kx450f and that gave it plenty of power all the way around!!!! I wish i had more of a choice with different end tips and silencers. If you are you lookin for a good pipe right here it is!!! Sounds awsome to!!!!

Q: T-4 vs. ti-4
Over 9 years ago
just want to know what the main difference is in the ti-4 complete exahust and the t-4 complete. is the ti-4 really worth the extra money or is the t-4 just as good?

A: Both pipes are identical as far as performance and construction goes. The only difference is that the TI-4 is going to be titanium and is a little lighter than the T-4 which is a stainless exhaust. If all you do is strictly track riding I would use the TI-4 if you do track and trails I would stick to the T-4
Q: Buying separate or together?
Over 9 years ago
What is the difference in buy the system separately ( header and can) or complete system?
Expert MotoSport Staff
Over 9 years ago
A: With this particular system you will get a different style head pipe that is not sold individually. It only works with the Pro Circuit GP Complete system. You gain more bottom end performance with this exhaust.
Q: Is the 98db sound good for the new ama sound regulation?
Over 9 years ago
i saw that this exhaust says 98db and was wondering if this was ok to race ama with because i thought the regulation was 98db?
MotoSport Staff

A: The AMA sound specs should be either 98db's or below so yes, this exhaust is ok to run in AMA races.
