Hi all,

I just got my 07 328i coupe not too long ago (used of course), so I am new to BMW modding.
I did do some searches but I can't find all the answers I need.

Previously, I drove a VW GTI with 1.8T engine, getting a downpipe + catback exhaust = turboback/full exhaust, which is the best option for modding exahust

However, I found no full exhaust system for 328i, and no downpipe mods, etc.
All I found are "muffler systems" (for ex. the Remus powersound: http://www.bavauto.com/se1.asp?dept_id=204#top ) Am I looking at the wrong direction?

I also found people recommending deleting the RS, not sure what that is, please explain?

Thanks!

Vincent

well we don't have downpipes, but we do have complete systems such at the bmw performance exhaust or the MMW exhaust setup which is basically straight piping from the headers to the muffler. Eisenmann also offers complete systems but they are on the expensive side. There are full systems out there you just have to look.

I think if I remember correctly Meisterschaft's muffler for the 328 is nearly $2000 not including the mid pipes.

You want full exhaust sans headers? Delete the secondary cats, resonator, and replace the muffler with a different one like the MMW CS Version 2. That'll give you an emissions passing setup while still gaining power and making children cry.

Its really not worth doing a full setup on our cars unless your custom turbo or supercharger .........

Just that price alone makes me cry..... Srsly my car came with one of these on it.... I am about to modify the exhaust. So who wants a used meisterschaft muffler?

So a full exhaust system doesn't do much for N/A engines, or that it's just not worth it right.

What about deleting the secondary Cat and RS, what are those? I am not familiar with deleting anything...

Headers are always good.... Price isnt, there is no company that makes an affordable header for our car (that fits right).

Ill pm you later. I need to take it to a shop to have my exhaust modified. Germans dont have many shops to do that.... (bend piping that is)

Well, if you want noise, grab the BMW Performance Exhaust and Intake (why not grab it from Tischer for the sake of saving money) and do a cat delete.

<-- sounds pretty nice no?

*Disclaimer: I didn't do this, I'm copying the video link from another guy's thread.

Our cars have primary catalytic converters built into the stock manifolds, follow by a set of secondary catalytic converters which are completely unnecessary, follow by a resonator that muffles some sound and reduces harmonic vibration in the car, and lastly followed by the muffler. Biggest sound reducer of all of those is the muffler. Doing the 2ndcat and res delete isn't gonna make a massively noticeable difference in sound. The muffler is the key.

It depends on which meisterschaft muffler you get, touring , race? and titanium
I have touring, and its plenty loud with mid pipes
Titanium is insane though at 2k for the muffler
Muffler new is ~$1000+shipping
midpipes are ~$900


To OP, there are full exhaust systems, but they are very expensive. I got one hell of a deal on mine, or I was about to cheap out and do a muffler delete

Thanks so much for your reply buddy, it makes sense now

I forgot to mention, I am looking at HP gain too aside from sound, that's the reason why I asked about the downpipe+Cat

Does changing the muffler and deleting 2nd cat+RS do anything for the HP?

Thanks!

You are really not going to get any hp from any kind exhaust for our car. Most would be 3-5 hp. The exhaust will flow more freely but the secondary cats and resonator primarily only help the sound. Your best bet is to find which exhaust sounds the best to you
