Just go to a muffler shop and tell them what you want to do

You need a custom job

go to the NA section of the forums. a lot of people have done it. but they are right, its a custom job. u need to but a new muffler too. there is no point in wasting your money buying a 335 oem exhaust and putting in on.

even if he wanted to, he couldn't because of the NA's storage box.

OP- if you want a really legit job done, get a 335i trunk storage box and an aftermarket 335 exhaust.

Thanks for all the good tips everyone.... and "fifa" ^ i was thinking about also getting a 335i aftermarket exhaust, are the storage boxes replaceable?

Dude I did the full convertion all OEM parts!!! And it is a big job. There is some part that need to be relocated, and two hoses, one from the engine compartment and the other comming from under the gas tank. If you want it done the right way and be all oem it is going to cost you $2000 to $3000. I'll recomend from my own experience to get and aftermarket or custom pipe run from one side to the other. Good luck.

$2000-3000??! man you got RIPPED OFF. people are practically giving away oem 335i exhausts on here, oem bumper is no more than 250.

do you have pics? i'm interested in seeing what this looks like.

If you interested in the duel exhaust search the forum. They was a few people that did it on here and posted video. I believe they did it with a magnaflow exhaust and it was not over $1000. So I would do some searching and you should be able find it.

His estimate may be a little high but it's definitely about $1500 in parts according to my research. An aftermarket 335 system is just over $1000. All the other bits (storage well, heat shields, exhaust hangers, parts to relocate the charcoal canister, etc.) is about another $500 from Tischer. You could save to money on these parts if you pulled them out of a junkyard but that would take some leg work. If you hired someone to install all this stuff you could reach 2 grand. As stated above it's a large job but it's doable.
