'the bigger sewer pipe the better'


so take it either way...run a big downpipe with a cutout, or run 4 inch all the way back.

If you do want the big pipe, I'd say by mindful or two 'issues': Wacky bending in the back to make ti fit, or if you don't bend it, extremly low exhaust in the back. Now obviously you could run the oval 4" stuff out the back if you're set on it, but it's up to you.

I'd personally opt for the electric cutout...loud when you need it, and quiet when you need it.
