I want to install headers on my 85 GS what kind of headers should i buy and how big is the pipe so that i can buy some strait pipe to get installed, with a glas pack at the end o ya and where is the best palces to buy one i live in canada ontario near sault-st-marie

 

From what I've heard, the only way to go would be Racing Beat for headers/exhaust. Also, if you put a glasspack on it will burn up in short order. The exhaust from a rotary engine is way to hot for anything but stainless steel. I think you can get a complete RB setup for around $650.00.

 

I have a 13B header if you want to start from there. PM or email if your interested
