so im repainting my car and i was wondering if you guys think i should just get the single outlet mtech rear for my 328i while im getting my car painted, or just get the oem repainted and wait because i want to get a custom quad exhaust set up!

any insight?? what would you guys do??

buy mtech rear and just keep single outlet exhaust or wait for the quad exhaust??

I'm a 335xi owner so take this however you will, but imo, get the m-tech rear and keep the stock exhaust (maybe look into some new tips, aka cyba or dimisa) and get the quad exhaust and a diffuser later on. Just my 2 cents.

I think the mtech bumper for 328 and 335 are the same, just the diffusers are different. buy the mtech bumper and quad tips diffuser and install them if u sure u gonna go for quad exhaust. the driver's side outlet on single tip diffuser and on quad tips diffiser are in the same place.

Well, I was talking about E90, if u say E90 and E92 r different, then thats another story..

[yxjackxh]

well i wanted to get the 335i bumper because the placement of the exhausts is how i want them to be. On the 328i bumper im going to have to alter the opposite side of the bumper to fit the other exhaust tips but they are too far apart, which i dont really like the look of it.=/ but thats just my opinion!

Bumpers are the same only diffuser is different. I have a 328 and made the conversion to the 335 setup. Just realized you have a e92, sorry

bumpers are identical. get the mtech now. you can get a quad diffuser later when you get your exhaust done.

[Dark_Knight_335]

Shim has the right idea.

[shim!]

OP, you can change the exhaust outlet position from a 328 single diffuser to 328 or even 335-style (more centered in the bumper) with a new diffuser and an exhaust shop. Just get the M-tech now

just fyi, thats a "328" quad exhaust. it is NOT the same as the 335 quad exhaust. the "drivers side outlet" are definitely not the same for 328 and 335. there are quad setups for the 328, and then there are 335 quad conversion for the 328.

but yes, whether you have a e92 or e90, if you have the mtech bumper, you can change the diffuser piece later. e92 bumpers are the same with each other, and e90 bumpers are the same with each other. just dont try to mix n match e92 and e90.

Oh so if i get a 328i mtech rear, i can later convert it to make it look like a 335i quad rear? how does that work? because the 328i mtech rear already has the single outlet on the far left as opposed to the 335i the dual exhaust is more inside in the middle, which is the look i want compared to the far separation of exhausts for a 328i

you can just take off the "328 diffuser" and replace it with a "335 diffuser"... BUT you will have to get the exhaust/muffler piping re-done by a shop to fit the outlets. and you keep the rest of the bumper the same.

Yes.

Obviously, you should do this now so that you don't end up paying to paint two bumpers (stock AND m-tech in the future).


To restate what everyone else has already said:

- The m-tech rear bumper for both the 328i and 335i are identical, except for the diffuser.
- You can buy the 328i m-tech rear bumper now, and keep the stock 328i exhaust and stock 328i diffuser until you are ready to change the look.
- When you are ready, you can simply purchase a new diffuser made for 335i m-tech rear bumpers, and replace your 328i diffuser with it.
- In addition to changing the diffuser, you will need a custom exhaust setup if you want something that looks like a 335i.

I did this exact same thing years ago. I bought a 328i rear m-tech bumper and later replaced the diffuser with a carbon fiber one made for a 335i. Then I bought some quad tips, got custom piping done, and now my rear end looks like this.

The remus quads made for a 328i are spaced out farther than 335i quads, so you won't want that. I wouldn't want to hack up the performance exhaust to do a custom quad setup; it probably won't be as loud as you want it to be after the extra piping muffles the sound.

I personally think the best route (and from what I've seen, most popular) is to purchase your own tips, a magnaflow muffler or something like that (search for the models people have used) and get a good shop to do the custom work for you. I purchased my tips from "cyba", a vendor on here. You can search for his threads and check out his selection.

If you can stand the drone and don't need the muffler, then you just need to buy the tips and get straight piping done.

Yes, u r right, I was just talking about the driver's side outlet of stock 328 and quad tips 328, nothing to do with 335

yeah ill probably buy my own tips, as long as the sound is much more aggressive than it is my stock exhaust ill be satisfied=). because i dont like it too loud either. do you have any sound videos or anything?
