swap exhaust

[manofgun]

hey guys,
i really want to delete my spare and do a dual exhaust on my swap that looks close to the m coupe exhaust (2 mufflers 4 tips).
first of all is it even do able and second i wanted to go with supersprints on TMS but don't know what kind of modification it will need to work.

keeping that in mind, i want to put supersprint headers on also.

As to your question, if you want the M Coupe exhaust, use it! I beleive someone else (maybe several people now) have used the M Coupe/Roadster dual (quad outlet) exhaust on their swapped ti's.

I beleive the piping is easy and only the hangars need to be figured out.

The spare does need to go away of course, and I think the original muffler heat shield needs to go as well.

Others will have to help with the other install details!

If youre going to use actual stock mcoupe mufflers, id advise buying something else. The catbacks are extremely heavy, though sound good. Removing the spare isnt enough to get the catback up there just right, itll sit a bit too far below the diffuser or bumper cover, depending on what you have back there. An aftermarket set of mufflers or mufflers, cat, and resonator under the main cabin, and Y at the diff may be a good option. I had two mufflers and resonators for my dual setup.

I now run a single mroadster catback to the drivers side, though its the passenger sides roadster catback.

thanks man i'll have to keep that in mind because i do want to keep the m-tech diffuser. do you have the 323ti diffuser? it looks really good!! also why do some ti's that i see on here have the outside b pillar painted body color (like yours) and others (like mine) are the black?

they're all painted, BMW just put black vinyl over it which some people remove
