For better flow and improved performance, our oversized version has a 2.25" inner baffle instead of the standard 2". For the 68-69 427 we upgrade the headpipe to a full 2.5" like the 454 version. In studying the original 1969 style sidepipes we found the weak points to be the end plates and inner supports. To compensate for this weakness we now make these parts out of stainless steel for both our aluminized and stainless steel sidepipes. With our CNC bender we are able to manufacture a sidepipe that fits perfectly every time. We buy top of the line materials and craft everything by hand. Our 9000 series Sidepipes are geared torward higher horse power cars with larger diameter inner baffles for better flow. 51 LBS
