GP Slip On Exhaust for Triumph Motorcycles

I’ve been running them for about a week now. I personally didn’t notice any difference in performance. They hit about the same as the stick exhaust on my thruxton rs…which is not a bad thing, unless you are looking for a performance boost.

The sound however…Damn! These pipes sound good!

They are deeper and just a tad louder. They have a kind of growl to them that is just wicked.

Also they are just a stunning pair of pipes to look at. The craftsmanship is mint, and they were a piece of cake to install.

If you’re looking for pipes that are aesthetically pleasing and sonically beautiful and distinctive. These are winners.

Note: I blacked mine out so disregard that aspect…just want to show that my testimonial is legit.

These GP slip-on's have made a big difference to the sound and performance of my st9. It seems as if the bike has woken up a little bit. Maybe not too much of a performance increase but there's definitely something extra there. Stock exhaust was OK but the gp's are another level ,better in almost every way. I love the look and if you can afford the change do it already.

Perfect look and aggressive sound to finish off my performance upgrades. I wanted a TIG welded GP look that matches the racer yet modern styling of my Speed Twin. Installation was a breeze.

Note: these videos don't do justice to how good this exhaust sounds. Especially from the 1200cc engines. The tone is a sharp and aggressive race sound, not that low barrel chugging from other bikes.

If yours is a 1200cc and you're considering the GP Slip-ons, then you need to check out this video for the best idea of sound: https://www.youtube.com/watch?v=6e2gvveR_HE

I had a little issue with the throttle side exhaust touching the shock BUT I have aftermarket Progressive suspension so that might have been the issue. No biggie, I heated/slightly bent the bracket, used one washer and it clears just fine. Also the bend clamp spot welds popped when I tightened it. Probably my fault (over tightened). I called BC and with no questions asked they sent out a new one. Great customer service.

The bike sounds AMAZING, performs well and looks unbelievably.

Bottom line is that I’m very happy and would recommend this product.

Welds look great but the fitment leaves alot to be desired. The right hand side is all over my shock. Tried to torque it to clear and then tighten the clamp, but the cheap clamp would not get tight enough to hold it in place. Going to order some quality exhaust clamps and try again. Otherwise it's going back.
