Details

    The Pro Circuit T-4 SA Complete Exhaust System is designed to provide some of the best performance and lightest weight for your four stroke machine. Made from premium stainless steel and aluminum, the T-4 SA is an extremely strong system that still manages to weigh less than your old stock exhaust. The stainless header and mid pipes mate to an aluminum silencer and work in conjunction so you get better power from the low rpms all the way up to the top of your power band. The silencer also helps lower your machines decibels thanks to a re-packable expansion chamber and optional quiet core insert that easily puts your bike below regulatory sound limits for both track and trail. All together, these design choices make the Pro Circuit T-4 S/A Exhaust System perfect when you want a full exhaust setup to take on the fastest tracks and into the deepest woods.

    Specs:
  • Full spark arrested exhaust for your four stroke dirt bike and ATV
  • Comes with stainless header and mid pipe
  • Round aluminum silencer body with aluminum end cap and nickel plated connector
  • Quiet core insert available
  • HP gains throughout range
  • Designed for easy disassembly and repacking
  • Removable USFS approved spark arrestor
  • Meets AMA sound restrictions

Pro Circuit T-4
Wow this thing is amazing in all fields. Rear section is a slip on so fitment is easily done. Finish and sound are what you would expect from Pro Circuit.

Great upgrade for a trail bike
This pipe give the bike a little better performance, sporty look and good sound. It is a little loud but not a deal breaker. You may want to took into a heat shield. It does get super hot. You will burn yourself at least once.

Go fmf instead save yourself a headache
Definitely would go FMF had three of them in the past no issue, this is my first pro circuit total crap fitting first off the flange wouldnt even touch the engine without removing the brass exhaust crush washer all together, then the pipe was touching the piggyback so had to move that up, then had to "push" the exhaust end to the bike and bolt it in cause wouldnt line up right.. should saved the box total crap pain in butt to deal with.. go fmf

Great System
Install was very easy. Fitment required a simple modification to a bushing on the mounting bracket. A solid, well-built system. Much lighter than the stock pipe and the sound is awesome. Well worth the price and the service from Rocky Mountain is the best.

This product is great! My previous exhaust was cracked and I never thought a new exhaust would make as significant of an improvement as this did.
The exhaust came quickly In a sturdy package and fit right on to my Crf 230f. My throttle response seems to have gotten better and the sound improvement is not even comparable to what it was. When riding the bike you really understand why you paid for something that seems to be pretty exspensive, it sounds deeper and gives a much better growl. If you are on the fence deciding if you should get one, just buy it and you will thank yourself later.

Better than OEM and cheaper.
After the kids rattled the stock pipe on a TTR110 off the bike I bought this to replace it. Bolts on super easy and is made of much thicker tubing than the OEM pipe. Not much performance to be gained on such a small bike but it is solid and runs nice and quiet.

Is it a 2 piece or a 1 piece?
A shopper on May 29, 2017
BEST ANSWER: The Pro Circuit exhaust system is 2 pieces, the head pipe with flange and the silencer.
is there a heat shield for this pipe?
Mike n on Apr 6, 2017
BEST ANSWER: There is no heat shield. You would have to buy an aftermarket heat shield. You will also have to rejet your carburetor as it will lean the pilot and main jets.
Do you have to rejet the carb for this exhaust?
Conner O on Sep 24, 2017
BEST ANSWER: I bought this for my wife's klx140 and for my daughter's crf150f and I didn't rejet either of them. They run great with the exhaust on, but neither of them ride in the higher RPM, but don't think that would affect it much either. Hope that helps.
Which Quiet core insert fits this product?
Andrew C on Apr 10, 2017
BEST ANSWER: Any 3.5" should work. With the stainless steel header, a nice stainless will really have a nice look!
Is there a Quiet Core Insert available at RMATV for the Pro Circuit exhaust Part# 1088800029 | Mfg Part# 4Y08110 ?

This is for the 2017 Yamaha TTR 110
Dennis H on Mar 29, 2019
BEST ANSWER: Unfortunately, we do not carry the quiet core for this pipe. I apologize for the inconvenience.
Is it possible to get a link to a photo of what the actual exhaust looks like for a klx110? is it the same as the sample picture or is it the newer nicer t4 with the cone end cap?
Jake W on Jun 27, 2017
BEST ANSWER: Mine is for a CRF230F and it looks the same but, the stickers are different. It really helped with performance. Especially after re-jetting. Its a much better feel.
Will this fit a 2018 ttr110 ?

I have a 2019 KLX140G i am thinking about getting this but don't know what size jets to get after
re-jetting so does anyone know the best size of jets?
Anthony A on Jul 8, 2018
BEST ANSWER: Being that I am unsure of your elevation I would recommend calling pro circuit and they should be able to give you a recommendation.
Their phone number is 951-738-8050
What is the weight on this pipe, cannot find it on the site?
A shopper on Oct 24, 2019
BEST ANSWER: It is way lighter than your stock exaust. Good pipe for the money. It brought our CRF230F to life.
Do you have this exhaust to fit a 2012 pitster pro double x 150??? I have seen a few with them...
david h on Mar 13, 2019
BEST ANSWER: Unfortunately, we do not carry this for your machine.
What is the decibels rating for this exhaust on a crf230f? I want to know if it will comply with my trails regulations of max 94 decibels. Also does it come with the Quiet Core insert when ordering the TA S/A complete system?
David D on Feb 13, 2019
BEST ANSWER: Yes the s/a in part number means spark arrestor.
I dont know for sure the decibles but I think you should be fine as it is not that loud.
What is the diameter of the straight pipe? I want to order a generic heat shield and for the T4 and want to make sure im not getting an oversized cover more suited to motocycle. Im asking for the T4 for a 2007 crf230f. Thanks
David D on Feb 4, 2019
BEST ANSWER: Love the pipe, but mine’s an ‘86 XR100RR. 🏆😆🍺
Will this fit my 2015 KLR 650? Thanks

For the Honda XR650R fitment what does the end cap look like? Is it like the one in the photo or is it the cone style? What is the difference between the two? Is it just newer vs. older style?
Colin D on Jul 27, 2018
BEST ANSWER: I don’t know on that model I bought one for a Honda crf150f an it looks just like the picture
So, I have a klx140G, and found basically this exhaust looks the same as a different t4 but with a powerbomb type thing on it, are they the same?
Jaycob P on Jun 4, 2018
BEST ANSWER: If you are going off of the pictures, they are just generic photos. When you order this exhaust specifically for your bike, it will come to fit that bike. From what I understand Pro Circuit only makes one style exhaust for that bike.
Does this fit a 2005 crf 150f?
