KA straight-pipe Problems...

[slideways31]

Probably a complete noob question- Working on throwing a straight pipe on my s13, I need to figure out how large the flange is on the bottom of the exuast manifold so i can weld one of the same size onto the straightpipe. - does anybody know what it is?

thanks

That's a 14 Setup and any SR Downpipe will bolt to that.
Unless your making your own then any 3-Bolt flange from 3" and under should bolt right up.
I can assure you it will sound like shit though.

Just cut the flange off the old downpipe and weld it to the straight pipe. I agree with the response above though, its going to sound like garbage. Weld in your old cat or just straight pipe to the factory muffler if you enjoy your hearing and being able to talk to people in the car.

for the sake of everyone's ears around you, don't go straight pipe unless your KA24DE is turbocharged.
