Under or over?

When I saw the title of this thread, I thought it was going to be about the Great Toilet Paper Controversy.

:D

1st gen under.

(And oddly, that's the second time today I've been asked that question, and I can't remember the time before that...weird)
 
Alright nerds, thanks for the help. :rolleyes:

Anyone with a 2nd Gen Rx-7 have any input?

Under. A 3" pipe won't fit going over the axle.

Where the pipe goes under the subframe will be the low point on the car, be prepared to replace it often :)
 
Ok, thanks!

Here's a quick follow-up. PRACTICALLY speaking, is it worth it to re-tune the ECU when going from one kind of high-flow exhaust to another?

I'm not talking full-stock with cats and small pipe to full-race exhaust.

I know this is percentages, and I'll probably do it anyway, but it seems unlikely to me that the maps could change that much. Anyone have experience with this?
