Great product second time buying them for 2 Hayabusas great sound and performance, specially after cat delete 4 to 2 header ,great look,and sportbiketrackgear is awsome to do business with

Best fit and sound for the HAYABUSA

Pipes create awesome sound at low and high rpm, finish and detail of fabrication on point,light weight, M4 have graphics with gains in hp, if using a power commander they have maps available for this set up already big plus ,only mod was one washers behind each bolt holding the kick stand , extra 5 minutes of work and done

Read the reviews and watched tons of videos. Selected the M4 and read that most people installed in about an hour. My 16 year old son installed these for me including taking the old stock cans off in under 20 minutes. They sound awesome. I can't wait to ride in traffic tomorrow. I will be so safe now. At least that's what I tell my wife.

STG made it very easy to place my order online. My items were delivered on time, well packaged and in excellent condition. I ordered slip-on exhausts for my Hayabusa so there were no installation instructions necessary. Very happy with my decision to go with STG. So much that I've already made my second purchase.

As you can assume, I purchased this product because I liked it and wanted it. I did some Internet research and read lots of forums about the product before I made the choice. STG is easy to buy from. Good prices, you'll get it fast, and standard shipping is free. Very cool. I also like watching the videos on line to. This was not my first purchase from them either. The package arrived, (from M4 in Texas), nicely boxed and padded. Exceptional appearance and zero visible defects. Fitment was a different story though. I expected the issue as I've read it on forums, but knew I could make it work with some effort and tools. The right side, (brake), did not slide in far enough to line the foot peg bracket hole with the exhaust bracket hole and needed to move another 1/2". The left side, (shifter), was a breeze. Slid in and lined up no problem. While the right side was an issue, M4 packages a portion of antiseize to lubricate the pipes joining, and prevents them from not coming off when you want them to. Issues aside, I had it all loctite, bolted, and torqued in an hour. After cleaning the pipes, I started the bike, and was taken back by the sound. It's a bit loud, but will help keep me alive in traffic. M4 makes a more substantial baffle to quiet it down, (purchased separately). The tone is perfect. Not the high pitch screaming you get from other pipes. In short. I love them. Great sound, great looks, great price.
