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.
Put it on a stock 230f and it sounds great. Fit very well no modifications necessary.
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!
Looks good, sounds good. Thumbs up!
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.
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.
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
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!
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!!!
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.
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!!!
Just bought this for my 03 CRF150f. Gave me alot more power! Deff seen a difference as soon as i put it on! Has a really nice sound to it as well! Deff louder then the stock pipe! Deff worth the price! Would deff put on my other bikes!
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!!!!!!!!!!!!!!!!!!!!
it gives lots of power i put it on a 125 and it gave it a lot of power abd it sounds great
i put this beast on my crf150f. I did''t think that this exhaust would add as much power as it did. sure i though yeah my bike is going to sound better and it did. The thing looks great on there too, i certainly recommend. you won't care about the price when you get the result. The only problem i had was i got burnt 3 times cause it has no guard over it but i got some exhaust wrap, put it on their and that fixed it.

First off, I have more items on my Quad, just wanted to list the basics for those who don't have a large income. The photo is when I first bought it. I am writing a review on this product based on my experience with it on my friend's Quad. We both ride the same Quad, have almost everything identical....except he has a T-4, I have a Ti-4. The only real difference is that the Ti-4 is lighter titanimum, and looks better once it is used a few time(pipe has so many colors). The T-4/Ti-4 complete exhausts are great for Kawasakis because they are developed by the Factory Teams. When combined with a aftermarket Fuel Controller and improved airflow, this exhausts performs as well or better then anything else on the market. Take your time when installing any pipe because you can easily damage the look or worse the function of the pipe. So wether you choose the T-4 or Ti-4, you know you will be getting a good product from a good company.
I have a suzuki 125L and it gave it so much more power than the stock. Its a great thing to get if you want more power and "get up" I will have this system on all my future bikes, you cant go wrong with this one. It took me maybe five minutes to put on and it fits the bike perfect. You cant beat the price, i looked everywhere and this site is the cheapest and most reliable.
this was the best pipe that i have ever ordered in my life it gave my bike so much power
I have a 2005 Honda CRF150F and I have a pro circuit T-4 Complete exhaust system on it and it has alot more power of stock exhaust. It sounds awesome and i got even more power out of my bike by off setting the cam to stay open longer on the intake valves. The only problem I had with this exhaust was I kased it on a 40 ft. double and bent the exhaust in a little bit but it didn't take much to bend it back. My next bike will have a full pro circuit T-4 exhaust system on it. I love them.
