This is very true also, you make a good point. They are all super expensive, but considering a standard Perforance exhaust is 1.3k its not too eye watering.

On the flip side, many have spent 6-7k on an evolution system with good reason. (fittment, warranty, worksmanship, harmonics, materials, visual appeal ++++ any other RnD involved in making an exhaust).

You may be able to find or custom make a 135i quad diffuser that has 56cm tip spacing.

Might be able to pick up an OEM 1M exhaust cheap as chips, but Id assume you're after a bit more oomf than a stock exhaust.

Pros/Cons I guess flinch I personally prefer a simple bolt on solution.
where's the $1.2k from?

most of the pricings, if i remember right, seen are around the $500-$600 mark in parts i think (DIY) (assuming you don't custom make your own battery post+cables which saves boatloads) and the $1.2k figure includes a nice diffuser + 1M muffler... though yes, i agree you'd probably be after something with a bit more throat, and the price would probably end up quite a lot closer to the $2.5k figure anyway... point.. haha

can understand wanting a direct bolt on, but $2.5k is a ton of change for what is, realistically, purely for looks?

yeah, but compare a BMWPE to a berk or something, and it's almost a strange choice to get the PE 9/10 times lol. (unless you REALLY want that specific sound)

strangely, i can almost totally agree with and understand the decision to go with an evolution... if you have that kinda money, it's probably the better choice all over lol... besides the fact you're guaranteed to get that sound. mmmmm.

one day... haha

Froop has just advertised an oem 1M exhaust for $400. http://www.1addicts.com/forums/showp...postcount=4086 i didn't realise though until reading above that it sound's like quite a pain to fit to 135.

I can't believe the costs of some of those axlebacks. $3k for an axle back

I would absolutely love a quad but I couldn't imagine paying that amount just for the axleback.

Custom made quads are always an option. I had mine made up for less than $500 (axle-back). The fit is good and sounds great.

But it definitely doesn't look as gorgeous as these 3D/Evolution/RPI etc units when off the car.

First post, had to chime in on this one!

Just picked up our new 1er a few weeks back and keen to get cracking on a few mods, waiting for delivery of some AR downpipes, Cobb FMIC & Cobb AccessPort.

Now just been trying to figure out the ideal quad exhaust!

To be honest everything I have listed to (I know it is very subjective) seems to pail in comparison to the Eisenmann Quad.

This is a clip of a setup similar to mine:




This is another clip from southern bm (only gets on it @ 2:55)

Hey guys I know this is late but does anyone know if the exhaust setup that goes in front of the battery box (closer to the rear bumper) would fit with a 1m bumper and diffuser setup?

The 1M exhaust as you have described needs not just the bumper & diffuser but also the battery 1M battery tray, 1M battery, extended battery leads and the charcoal cannister moved a bit.

I have just done a quad for my 1M conversion check out my build log:

Or for the full 1M conversion:
