Mistral Big Bore Header Pipes, Flanges, & Y Pipe Set
Complete fitment list at bottom of this page.
Stainless steel header pipes, Y-pipe, and flanges set.
Full "Big-Bore" internal diameter continues from the exhaust inlet throughout the full length of the header pipes allowing better performance and providing a deeper sounding exhaust note.
There is a 50% weight reduction with these header pipes as compared to the original parts. And, thanks to the use of AISI304 stainless steel, these will never rust (the OEM pipes are mild steel and could eventually corrode).
This header pipe set includes two CNC machined aluminum exhaust flanges complete with Mistral logos. The header pipes have mounting points attached to enable installation of the original equipment heat shields.
Includes two new exhaust gaskets so you have everything you need for a complete installation.
No modifications are required, however the best performance is obtained by using in conjunction with the Mistral crossover, slip-on muffler and V-TWINBOOST thereby eliminating any lean fuel conditions.
