318is side exhaust fab idea

Also, don't expect the exhaust to be anything near quiet.

Are you planning on cutting and welding in a new tunnel for the side exhaust, or are you just going to have it hang low and poke out underneath the rocker panel?

I put a side exit exhaust on my M3, and had a proper tunnel fabricated for it and made it exit though the sideskirt. You can see it in my sig pic.

Most side exhausts I've seen on this forum have been ghetto rigged with no tunnel for the exhaust. It ends up looking like a piece of shit that somebody pieced together with a bunch of leftover parts, hose clamps, and coathangers.
Don't do it this way.

This is merely a wild whim that I am entertaining, and I am just looking for experienced feedback.

I did some research and it seems that a magnaflow 2.25" dia inlet/outlet from summitracing.com and a resonator does the trick for a throaty non-ricer sound.

(btw, any suggestions on resonators? How about this one? http://www.summitracing.com/parts/JE...2S-5/?rtype=10)

Anyway my weird and possibly totally stupid idea is this: replace stock cat/resonator w/ magnaflow muffler and a resonator, and simply turn the pipe to the side and exit before the rear wheels, as shown in this highly technical schematic:



The reason the side pipe thing even entered me brain is because I have been doing alot of rear subframe/diff/axle shenanigans lately and the catback bit is a real PITA to uninstall/reinstall all the time, and it weighs a ton. This way I could save like 50-75 lbs or so. Would be significant on a car that is at 2300 lbs currently.
