United BMW - BMW Performance Exhaust 135i Fly-By

unitedBMWonline is proud to offer you the sound of the stock 135i exhaust vs the BMW Performance Exhaust. The install should take about 30 minutes to 60 minutes. You will have to cut (like any other BMW Exhaust Install) the first set of resonators off, and replace it with the piping and muffler provided with the BMW Performance Install kit.

The Convertible has the stock exhaust, and the Coupe has the Performance exhaust.

If you are a current 1 series owner, we offer this exhaust for the 128i and the 135i.

How much would you guys charge for Performance Exhaust on an E90 328i installed? Also, when the F30 3ers start rolling out will it be harder to find this exhaust system for the E90? Thanks in advance.

@stigger91 BMW will continue it's BMW Performance product line as long as there is demand. Rest assured, the new 3 will receive BMW Performance products!

As you can see both cars are new, not yet broken in and raced well beyond the recommended break-in rpm without even being warmed up first. So when you buy a new BMW at United BMW, you know you're buying a car that was probably abused by the service staff. Thanks for the comparison though, I'm definitely sold on the BMW Performance exhaust.

@aarontharris As we've said in previous posts:

These cars were the 08 test vehicles, first on the lot that were driven by every customer. We didn't just take any car to tear up, these were already ragged by many customers who decided to take a test drive.

We do hope you enjoyed the sound of the exhaust! :)

I have a 2010 135i white with red leather loaded with M-sport and 6 speed manual. Love the car. Doing the Dinan stage 2 software next week which will bump up the HP to 384 (300 stoick) and torque to 421 LB FT (up from 300). I am wanting to do the free flow exhaust as well but can't decide on the BMW performance one VS the Dinan one. Any comparisons would be helpful....anyone. Thanks

[UnitedBMW]

@GCBBLB BMW Performance is a free flowing mid-pipe and also a free flowing muffler. Dinan is nothing but a muffler. Dinan is also quieter, but is better looking. Best bang for the buck is BMW Performance, as it is $850.00 shipped from us

Great comparison. Thanks for putting this up.

I'll go for the Performance exhaust. Definitely. :)

The 135i will beat the shit out of a GTI!

Respond to this video...  i love how you can hear the turbos spool from far away

[djchexxxx]

@stigger91 FYI, 328 engine is completely diff from the 35s. the sound will vary greatly due to the turbos

[Razor4ever]

These cars are fast not doubt, but they do not sound nice. Its not deep or a good high pitch tone. 370z sound a lot better and G37.

But Id still take the BMW over them.

[Charlie135i]

any 135i owner .... how good is the turbo whistle in this car???

[stigger91]

@aarontharris The cars were sitting there idling for lord knows how long, I guarantee they didn't flog it on a cold engine. Besides, most dealers can be much worse.

@UnitedBMW Thank you for the feedback. You say the Dinan muffler is quieter than the BMW performance one? From You Tube, the Dinan does seem to be fairly tame at idle but when you step on it the sound seems to get pretty sporty in a classy euro sport way. Does the BMW one have any drone? How loud is the BMW one VS the stock one on a scale of 1-10? I hear that the 2011 135i has a different muffler again and apperantly it is a bit louder than the 2010. What does replacing the mid-pipe do? Thanks
