The T-4 System is a tunable version of Pro Circuit's more exotic Ti-4R System and includes the all new, sound-reducing RC-4 Resonance Chamber. Pro Circuit developed T-4 Complete Exhaust System with the intention of satisfying your motorcycle's thirst for more power at a reasonable cost. It will boost your bike's overall power by not only adding raw performance but will also add power by shaving weight. The durability of the T-4 is beefed up by using stainless steel for the head and mid pipe. Pro Circuit stepped up the performance of the T-4, making it tunable by including both spark arrestor and race tip so you can choose your end cap to match your riding conditions.

  • Lightweight 6061 T-6 aluminum sleeve.
  • A removable U.S.F.S.-approved spark arrestor and race tip are included with every exhaust.
  • Maintenance on the T-4 exhaust is simple with the bolt-on removable end cap.
  • RC-4 Resonance Chamber to reduce noise.
  • Billet aluminum mounting bracket.
  • Meets AMA / FIM sound requirements.
  • Note: The RC-4 Resonance Chamber, depending on year of your bike, might not be included with the system.

The T-4 exhaust gives you the ability to take your dirt bike off the track to the unbeaten path with the U.S.F.S.-approved spark arrestor but, when you are on the track using the race tip, the T-4 will meet all AMA and FIM sound restrictions.

Amazing Exhaust

I just bought this pipe for my 2012 Honda crf100f and it sounds amazing. It beats better than the stock pipe. I would suggest buying it! I think Pro Circuit is a good pipe it sounds good. When you first take off it is just a great pipe and there product is one of the best brands but there pipes are expensive but it is worth it. I didn't need to rejet it or anything, just put a few bolts and it is ready to go!

Excellent product

Beautiful workmanship! Fit, finish A+. Had to modify side cover just slightly to miss pipe. Everything else cleared and bolted up perfectly. Sounds great (loud) Helps a little all the way through rpm range. No carb rejet required.

Great Pipe

Excellent Purchase for my 2005 Polaris Scrambler. My quad sounds like a 500 should with a deep but powerful and crackly note. This thing is loud and added a bit more throttle response and torque.

Best buy

I bought this exhaust for my crf230f and rejected the carburetor when I threw it on. It has a significant added amount of bottom end power and sounds great

Awsome

I bought this for my 2005 trx450r and wow what a difference! There is a lot of bottom end power gain, but especially a huge top end gain! I love this pipe because it is loud enough to sound great,but it isnt too loud. Its quieter than and fmf but gives a better deep and throaty sound. Its a great buy!

Great Add-on

Couldn't ask for a better upgrade for these pit bikes for the money you spend. Definitely a must-have.

BEST EXHAUST EVER

I got this exhaust for my cf150f and it sounds so much louder than the stock exhaust and it adds soooo much power!! It feels like a 150r!!! I definetly recommend!!!! But the exhaust in the picture is not the exhaust. If you want to see the exhaust go to youtube and type peachm10 in the search box and scroll through the videos and go to the one that says crf150f pro circuit t4 complete exhaust system. BUY THIS PIPE!!!

PC really lives up to their reputation

Bought this pipe for a 05 trx450r to replace some cheap aftermarket pipe it had. WOW this pipe now only sounds awesome but it aslo gave the quad more feel in the throttle and top end and over-rev are far better then before. I really did not notice much difference on the bottom end.

Sweeeet pipe

I got this exhaust system for my '03 125 suzuki and it made a huge difference, but i reccomend if u get this system re-jet the carb because if u dont ur bike wont be getting enough fuel and itll bog down, also i had to drill 1 inch holes in my air box and put some pops in it......all together i was about 260 dollars in but it was most definatly worth it...RIDE ON!!!

Will this sound better and give me more power than an FMF on my xr70?
I would like to know before i spend the money and im buying a BBR rev box for it also

Both the Pro Circuit and the FMF for the XR70 have very similar sound and power output. I have run both of them on my XR70 and XR50 pit bikes and could not tell much of a difference between the two. The Big Gun Evo Mini Complete Exhaust is also a good pipe and has a little different sound and a trick looking end cap.

With this exhaust will need to re-jet the carb on 2011 ttr110?
MotoSport Staff Expert
Over 9 months ago
MotoSportExpert
The jetting really depends on how your bike is jetted now, but normally after installing a full exhaust system you will need to re-jet your carburetor for optimal performance.
