im trying to keep the cost down on my 88' n/a rx-7 so buying a 600-700$ exhuast is not in my budget. now iveN made a good list of parts that i would use to build my own single drivers exit exhuast.

- 3" mandrel tubing
- 3" morroso spiril core muffler right after the manifold
- 4" dynomax race magnum welded muffler at the end with a 3"-4" reducer
- since im in the sticks out of seattle i have no emissions so that means no cats

so give me your opinion on this setup. ive got lots of fab. skills so i know i can build this no problem. if this setup is no good the only exhuast kit i could see buying is the corksport catback.

 

what kind of metal? SS Aluminized or mild?

 

mild steel to keep the cost down for a custom built exhaust

 

I had a friend who put stock s10 mufflers on his. They fit great sound great flow great and are cheap. Just stick a couple of nice tips out the back and your good to go

 

if you've got the fabrications skils you claim, then the only issue should be finding the right rear mufflers.
