As you can tell from the very professional drawing it’s going to be a simple 2.5" system with flowtech block hugger headers with an x-pipe going into a pair of Gibson M.W.A mufflers and then stepping down into the factory 1.75" pipes. The factory mufflers may or may not stay, it all depends on the noise level. I am going to keep the factory offset tips though, those will never leave. The cut outs will either be a homebrew set of throttle bodies with cables to open and close them or just the very simple blocking plate ones. I’m not really worried about the power since it’s most likely going to be a basic cast 350 with simple bolt ons, like a dual-plane intake, good carb, maybe a mild cam. Which should still make more power than the stock 4.2 rated at 175 flywheel horsepower (I think).

Tell me again why you need anything behind the cutouts?

Why are you keep your cats? required by law?

Here’s what you do. Go buy a cheap set of headers, a pypes 2.5 cutout kit, and some thrush turbo mufflers. You’re going to have 50 hp hiding in the exhaust with 1.75 inch exhaust pipe and restrictive factory mufflers.

See, with E90M3s improvements and mine together, you’ll really have something!!

Granted that something may be a “public nuisance”, but it would be an awesome public nuisance.

I’m pretty sure Doug Demuro would agree with me on this one. There was a Gilmore Girls scene for that one.

Nah, I’m not required by law to keep the cats i’d just prefer it not to smell like unburnt hydrocarbons since it’s my DD
