So i figured out that with a little modding and maching i can take a shorty header from a chevy and fit it to my rx7. I was wondering if this would be a good idea? 2 1/2" exhaust tubing, going to a single to double muffler at the end, plus two chrome tips, both angle ment like the stock look but nice and fat. Would that be ok? sound ok? Its a straight through V force muffler. Will 2 1/2 be sufficient.

 

I ment machining. And btw thanks for the responses. I want to do something becides racing beat.

 

I quess you can try the rest, then go to the best

 

Oh racing beat exhaust is like snap on or nike. I know thier **** is awsome but why spend 1000 bucks on exhaust that is only going to look pretier and perform just as good as my idea. Hey this way, il have something that has never been done. "built not baught"
