my question is will this work? I've searched and i can't find anything that has definitively confirmed this. What i have found are a bunch of arguments of what is better, IS or BMW PE. Having never heard a PE exhaust i can't compare but I've heard an IS and it sounds amazing to me. I was wondering if anyone has done this and can tell me if a 335 with IS mufflers (like the ones sold by tischer) sounds just like the 335IS? Any insight is appreciated. To me it seems that i'd be perfectly fine with it sounding like an IS, i don't care about the noise level, I'm more interested in the noise itself. On top of that it seems well worth it to go IS mufflers since it is half the price of the PE exhaust.

In theory, I *think* the rear of the cars should be identical. I haven't heard of anyone doing this though

[E90Company]

Yes it works. Yes it will fit. Yes it will sound exactly like a 335iS. It's mufflers, so AWD or RWD dousn't make any difference.

Me neither and it scares me bc it seems like a good idea so why hasn't anyone tried it...?

[holmes011]

can anyone else back it up that it will fit?

[bigdaddycane]

live boldly....install the "is" mufflers and report back to us!

[manolooo]

It works. I had mine installed today

[ken1137]

Yes, it will work. None of the exhaust vendors sell specific 'ix' and 'i' exhaust so it should be fine. I installed the 'is' exhaust on my 335i...love the sound especially since I also installed AR DPs. Install is very simple, cut and clamp. The only problem is the tips stick out too far so I'm going to have to change the tips. I think the 335is bumper & diffuser are a bit longer versus the 335i & ix. I just need to figure out if I have to cut and weld, or if the black tips just pull off, but this will have to wait for Spring.

how was fitment? did it stick out too far? How does it sound? any clips?

+1 picked up my car today and it works just fine. Love the sound, don't expect gains.

Gee, here's a thought that will take all the fun out of BMW parts roulette, ask Tischer before you place the order.

hey I like your sarcasm and i bet you felt good about yourself as you wrote that but i already did and they said they couldn't say for sure and that I should ask the forums

So what is MSRP and PN for the 'is' muffler setup?

I've actually been considering doing this as well since I happen to have an extra driver's side "is" muffler sitting around. Would just need to buy a passenger side muffler.

Is your car an E90? If so, then it probably won't fit or sound like a 335is. Whether your car is XDrive or not shouldn't matter, but the exhaust tips are usually longer on E92 Coupes . So you might need to cut down the pipes before the tips so it looks right.

Other than that, the E90 sedans have a resonator that makes them quieter than the E92/E93, which have an X-pipe instead. To get a true 335is sound, you'd need to remove the E90 resonator and install an X-pipe in it's place. If you've ever compared the exhaust sound of a regular 335i coupe and sedan, that's the reason the coupe's are always louder.

If you try it out let us know. I would have done it already, but I hate the "sleeve" clamps BMW provides to swap mufflers. I would have my exhaust guy weld them in for me for a factory look and fit. That's just me, though.

Well, I did...but more so in a helpful way.

But in any event, and if that's the case, my apologies. I actually knew that answer, as I too had called Tischer BMW to ask and told the same thing. I just didn't want you to be mislead by hearsay or guessing here on the site, as happens more than not. So a call would have been the most prudent course of action in this case.

So I too am interested and if you proceed w/ the 'IS muffler system, let me know if it works out.

Agreed, the clamps thing for me is something that I would tend to worry about. Having it welded like a factory OEM part would be my thinking as well.

Then it should be a very easy swap and it should sound pretty much identical to a 335is.

Yeah, it's how we are forced to do it for warranty purposes, but I don't like it. Not that they leak or anything -- they just look cheesy to me.

The thing that's really kept me from investing in the "is" muffler swap has been the performance gains, or lack of. A full downpipe-back system like HKS, ETS, etc. will give at least 10 rwhp for the effort, along with the sound. Plus you can keep your factory exhaust to go back to stock easily if you ever want to. I'm really loving the tone of the ETS system from the videos I've seen, so I might go this route instead.

Frankly, that too has kept me from the 'IS and PE exhaust, no bang for the buck.

if you are looking for real gains, look elsewhere...no exhaust is going to get any gains near worth while for the price you pay. So don't kid yourself...
