yea i gots a 92 hatch... n im just wonderin whats a good size piping.. with a stock muffler??

 

3.5" dual exhaust

 

With a stock muffler?

It depends on your engine set up...

Since you didn't list your engine I can't say much more than...

Turbo = 3" works nicely
NA = smaller than 3"...lol

 

It realy depends on your setup and horsepower goals. Most upgrade exhaust systems for N/A are going to be 2.25". 2.5"-2.75" will support Turbo applications to about 300 whp. Anything over that and you will need 3".

 

i was thinkin about 2.5..

5" dual stacks. Just like big diesels.
