No real need for pics as its' just two pipes under the rear that take the place of the muffler. I have a set sitting in my garage, if you PM me I can shoot you pics, but its' nothing really to see.

Sound is great, no real drone, sounds IDENTICAL to the ACM mod (search for vids) and looks much better from behind. Not too mention its' cheap and saves a lot of weight.

I have the muffler delete on my e92. It drones pretty good from 1500 to 2200 RPM, especially uphill on freeway. but i cannot count how many people pull up next to me and ask what i have under the hood and say that it sounds awesome (with huge smiles on thier face). everytime i think i cannot stand the drone anymore and want to convert to a muffler, i just haven't been able to do it yet. plus you save some serious weight and this mod can be done for very small amount of $. if you want sound, free flow, and low weight, you just can't beat this setup

I'm planning on getting an xpipe setup and keeping my stock muffler with electronic cutouts right before the muffler. This way I can have it scream when I want it to or tone it down a notch

If I was to add two valve tronic valves would it help with the drone when they are closed ?
