EJ22 Exhaust (in EA81)
Posted 08 December 2005 - 12:42 PM
I plan to use the stock headers. I will then start looking at doing a side-exit exhaust if it's not too laborous. Ideally, it will exit on the pass. side through the hole for the side-step blank (brat) with the piping being welded onto a sheet of metal that will cover the hole w/ two (or one?) ports from the piping to meet up w/.
Any better ideas? What size piping would be easiest, best on both high and low range performance, and sound good?
Edit :: What emissions parts should I retain on the exhaust system? I'm in MT so I'm most concerned w/ performance and quality of sound. Also, I'm trying to do this inexpensively, so if I buy anything it will be my buddy's used glasspack.

I was thinking 2.5" also. Should I just skip the muffler and cat.? Or should I at least run a glass pack? It might be too darn loud w/out anything.

Not to rain on anyones parade, but I thought I read somewhere in a rulebook, that all exhaust must exit the rear of the vehicle. This may have been for WRC and not Rally Cross though, and I maybe totally mistaken. But it would really suck to go through all the work of building a great exhaust system and then find out you can't run the car in an event.
Just my $.02

You may be correct though. I plan to use flanges at a couple of points to allow easy removal when necessary. As for autocross, I've seen some cars run w/out any exhaust exit unless you consider under the car an exit.
And if they won't let me play w/ them, I'll start my own darn club and not let them race w/ me.
