What is the best exhaust for e36 325

[Trev24]

Good day fellow BMW lovers:rollsmile:

I have an e36 325 and currently have the e36 m3 exhaust and branch fitted on . I'm looking for a bit more power and quite a few people are saying to go with a different exhaust system. I'm from durban so Primaforce would be my choice to do my exhaust .
However I love the noise I get from my current exhaust and I would hate if I had to lose it for barely any power gain.

Any advice on whether I should change the exhaust and branch or not ? Or could I expect a power gain that's actually worth it ?

Thanks in advance for the advice !!

My guess is other forum members would say the same as me:

Your car is already tuned to the limit, if it is decatted and you have the M3 exhaust on it, there would not be a huge, if any change, in the power output of the engine.

If you love the current sound of the M3 exhaust, I would leave it as is if I were you. :coolShake:

From my research the M3 branch is as good as it gets

These guys are messing with you....

Take off the setup immediately. You are losing lots of power.
I will happily assist you in disposing your current setup.

okay what about a cam job then ? i was thinking a 256 268 split, but thats well in the region of 15k with a good head job.

so quite frankly i don't know what to do or which route to take to get some power but maybe a chip with a good tune should do then ?

Firstly, what power gains are to be expected with the M3 branch and exhaust fitted to a standard 325i?

How would this effect the standard ecu? Will it cope with aftermarket cams or will a aftermarket ecu or add on be necessary?

can tune and stroking it out would make sense beyond that it is probably more cost effective to go with boost

I have the same set up as yours, M3 branch and decatted exhaust and I can't see you getting a better set up than that.

I felt the difference immediately after I've fitted the exhaust and even better throttle response after I've fitted the branch.

That's my opinion anyway.

Just curious, will the M3 ITB's fit the 325i motor?

I think you need to make up an adapter plate.....itb's with fuelrail and injectors go for around 4.5-6 k last time I checked. And then you'd have to run management I think

The exhaust you have setup is decent, don't fix whats not broken...
If you want power though stroke that mofo..those motors make for a nice 2.9 banger
