Pro Circuit T-4 Complete Exhaust System

Product Description

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.

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

Location: Middleboro, Ma

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.


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!!!

Ease of Installation

I got this for my 150 pretty easy to put on. When ever I rode my bike for the first time with the exhaust on it felt and sounded like a diffrent bike. IF I WERE YOU I WOULD GET THIS EXHAUST!!!!!!!!!!!!!!!!!!!!

Will this fit my kawasaki klx110l w/143 big bore & will i need to re-jet carb?
Expert MotoSport Staff
10 days 22 hours ago Location: Portland, OR, USA
Yes, this exhaust will fit your Kawasaki KLX110. 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.

Will it fit an 00 polaris sportsman 500?
Also what I'm asking is is this going to be a lot louder than my stock pipe? I'm looking for more power
Expert MotoSport Staff
2 months 10 days ago Location: Portland, OR, USA
Yes, This Exhaust System will fit your 2000 Polaris Sportsman 500. It should give you noticeable power gains and be a bit louder and deeper sounding than your stock exhaust. When switching over to an aftermarket exhaust system you may also want to look into a jet kit for your ATV as normally re-jetting would be needed for optimal performance.

Does this exhaust fit the 2012 yamaha ttr 125l?
MotoSport Staff
4 months 17 days ago Location: Portland, OR, USA
This exhaust is available for your 2012 Yamaha TT-R125L. Keep in mind that when installing an aftermarket exhaust, you may need to modify the jetting in the carburetor for the bike to run properly depending on your location and what elevation you tend to ride at. Also, these exhausts are model specific. Please make sure to profile your bike correctly when ordering so you receive the correct exhaust specific to your bike.

What size quiet tip base fits this exhaust? I have a 2001 yamaha ttr125l.?
MotoSport Staff
Over 8 months ago Location: Portland, OR, USA
This is a little more involved as it could actually be a couple of different models depending when the actual exhaust was purchased. I spoke with Pro Circuit and they requested that you send them an e-mail with a photo of the actual muffler so they can help you with what exhaust tip you will need. Please send the e-mail to with the request of what end cap you will need and they can get you taken care of on this request.
