With very little room to work in and no ground clearance i decided to make try/y design headers on this car with merge collectors instead of the slip on style
When making custom pipes i always make the hard side first, [most cases drivers side]

the left side has more room but the headers needs to flow the same as the right side and look similar

i have used interlocking flanges so there will be no gaskets required at these joints

The pipes from the headers are twin 2" which merge into a twin 2 1/2" free flowing mild steel system Because of very little ground clearance the exhaust tends to get knocked around so i recommended a mild steel exhaust system, no point spending money on stainless steel on this car
The exhaust runs very close to the floor so heat shields are fitted to protect the floor from heat transfer from the exhaust

the four original exhaust mounts to support the mufflers were salvaged and reused, flanging the muffler enables the full system to be remove in under ten minutes

rear resonators have also been fitted to
help reduce the noise without hindering performance, the chrome tips are 3"
