We're looking at changing the exhaust setup on our EA81 race wagon. We want to get it out of being bashed and because the radiator is in the back now we were thinking of brining the exhaust forward and up to the hood or maybe out the side where the jack used to mount.
Question is with only around 2ft of pipe on each head would it need to be joined as in like the y-pipe joins it or would running it separate not harm performance?
At the moment we just run the y-pipe, nothing else and it runs great. But after last race the left hand header got flattened to around 15mm thick in one section.
