      Comments about Pro Circuit - 4-stroke Ti-4R Exhaust System:

      This exhaust works great on my 09 CRF450R. It took a little off the bottom end and added a lot of power on top. 5 stars for the CRF450R. Unfortunately It wasn't so great on my new fuel injected CRF250R. It did add a little mid & top, but not much and didn't add any low end. It almost feels like its got a clogged air filter. 3 stars for the CRF250R. The Yoshi RS4 is much better for the CRF250R across the board. More power everywhere.

        I found this item easy to put on and effectively added more high end power to my bike. The titanium not only is light but relatively lighter than the steel.

          Just got my Pro Circuit TI4R Exhaust System for my 2011 Yamaha YZ250F from Btosports.

          I just got back inside after installing it, tok me just 30 minutes to remove the old system and install the TI4R system

          I havent been able to ride it yet, but I will do all weekend!

          Have alot of excaptations to it, but Iam pretty sure it will deliver those.

          5/5 !

          Comments about Pro Circuit - 4-stroke Ti-4R Exhaust System:

          The exhaust fitted easily and the power increase was noticed straight away, but no heat shield. Can't comment on all model types but the 2010 Kawasaki 450 header sticks out past radiator shroud quite a bit and melted my pant leg and a bit of my boot. Took it to my local welder and he TIG welded heat shield lugs in the same position as the factory header and I fitted the factory heat shield, all good. I have also sourced a carbon heat shield she will look pro then.

          Service and delivery comments:

          I am alway's amazed at how quickly i recieve products from BTO. With in 7 day's. Usually I can't get stuff that quickly sent to me from within my own country.

          Cheers

            I put this on a 2011 Yamaha 450 it bolted straight on with no hassle,it gave it more top end and a better note and took the jerkiness away that the standard exhaust gave it. It sounds and looks great.

            this exhaust is by far the best exhaust i ever put on my kx250f. It increase the power all-around especially mid to top, where it is very helpful on 4-strokes! I love the look of it, it has alot of stickers.

              installed this system on a 2007/and 2008 rmz250 and increased everywhere pulled much more on bottom and kept on pulling through mid and top. felt it the most in mid but increased everywhere. also installed on a 2010 crf250 also increased everywhere probably most in mid as well. best thing about these is the tone you get with them, can pick it out anywhere very satisfied and its super light weight!!
