335i BMWPE

[neverdone]

Just signed for my X1 35i M-Sport and it's already got Dinan stage 2 and BMS intake, so it's a start, I do plan on doing more mods. The thing I hate the most is the single outlet exhaust, it's blasphemy. I traded my n55 335 xdrive in for this and I was wondering if anyone has retrofitted the 335 BMWPE on this car?

I realize I'll need a modded diffuser but anything else ?

[fiehlsport]

I plan on cutting my muffler open to do the "PE mod" soon. Already bought the heatwrap and clamps. This should essentially convert the X1 catback into exactly what the PE is, without any fitment issues.

This is the thread I'll be referencing:

As far as I know, the other PE catbacks won't fit the X1 due to the cross-bracing underneath our cars.

I've been searching all over for an aftermarket diffuser to fit dual exhaust on here, has anyone found one or have one that has been modded to fit?

No aftermarket diffuser but you can cut the stock msport easily. Tough part is running the right side piping. You can run a narrow pipe but the bends will be restrictive. It's not worth it.. I run a modified 135 Active Autowerke rear section, but any exhaust shop can chop your muffler off and add tips! It helps keep the sleeper look and this car is pretty ugly from the rear so try not attract any further attention to it...haha

That's my point, it's ugly as fuck so I'm trying to pretty it up lol I guess I'll have to go completely custom.

I put in a catless downpipe along with a muffler delete along with a jb4 and the car is loud and breaks lots of necks haha
Should be posting a video soon

Some would think it's blasphemy to take a single exhaust, and split it into a fake "dual" exhaust.

[neverdone]

None of these cars are dual exhaust, just dual outlets so it's no difference.

See, there is a difference. BMW uses dual outlets not only for looks, but to have the ability to close one channel of the muffler under low-load situations. The "difference" is the fact that the 335, for example, uses a massive muffler, way bigger than it needs to be, for aesthetic reasons only.

Not that I don't prefer the look...just saying many would claim that wanting to add a larger, heavier muffler just to move an exhaust tip to the other side of the car for appearance is "blasphemy".

The lighter, more efficient muffler is blasphemy? That's a strange word for you to apply to a solution that makes more sense, for all reasons sans appearance.

[neverdone]

Blasphemy on the appearance side. It looks retarded. I don't care whether it adds an extra 20 pounds to my car, it's about the car not looking retarded with a single outlet.

Again, it is just aesthetics. I can weld it up without issue but I'm not sure I want to cut my diffuser to fit it up.

Prick.

Oh look, a contrary opinion greeted with an insult. And I even agreed that I, of course, like the looks of te 335/dual setup better.

If you are going to cut up the bumper anyway for aesthetics, why not go all the way and install quad exhaust tips

I'm personally good with the stock black chrome exhaust finishers, and the dual exhaust on one side of the car, but if you mind it that much, go custom and post pics and a vid

I'm trying to avoid cutting the diffuser. Maybe I'll find a used one and mod that. Quad tips were definitely my thought process going in, we'll see what I come up with.

Just an update:

DO NOT do the "PE Mod" on the X1's stock muffler. I cut mine open and was greeted by another shroud completely covering the internal pipes. It is not the same muffler as the 335/135 that can have the pipes wrapped.

Good to know! Thanks for the update! What are your plans then?

I don't see how you will get quad exhaust tips, or any sort of exhaust tip on the right side of the car without cutting, since the stock exhaust goes through a cut out

Me neither, I haven't had it on the hoist yet.

Did you happen to snap a picture of that?

[Shock96]

Personally I am OK with the single, it doesn't bother me a bit.

Seeing as this is purely aesthetic, you could just mod the panel and install one of the many fake dual exhaust tips. Get the look without all the hassle and weight.

I'm going to try and get it on the hoist this weekend, see what I can do.

Mwtrogus, how much effort did it take (ie. hours) for your shop to modified a 135 active autowerke rear section to fit your X1? What did they have to do?
