Custom Carpenter Sidewinder

leatal · May 8, 2019

Finally got my custom Sidewinder exhaust finished and installed. Gone are the upper springs and the ugly header plate. I left on the lower springs holding the collector to the primaries for fear of expansion and cracking of the stainless primary tubes. The performance gain with this system is amazing! The bike pulls really hard all the way to redline. May have lost a tiny bit of torque below 2500 RPM, but above 2500, hold on cause your going for a ride. In fact, open the throttle at any RPM and the front tire seems to want to go airborne- scary sh!t. I do need to thank R-3-R Turbo for the design idea and give Jheli a double thanks for doing the machining of the header plate and making the custom stainless header flanges. Thanks a million guys, the project came out better than I could have hoped for!

Man that is one sweet finish at the flanges.
Well done leatal and jvheli nice machining

I wonder when Carpenters will copy this!

Also fyi I welded the collector onto the headers in 2014, no cracking probs in the pipes, also ceramic coat since 2016 and it's still good too.

please post your address in Dothan so I can take a wee ride up and steal the flanges from your bike, I am not heartless I will leave you my sidewinder plate so you can start all over again
