But hpf exhaust is basicaly straight pipes....you could have paid a muffler shop to straight pipe+ add a resonater for much cheaper.
But none the less it sounds great

I still don't understand why people think 2000$ for straight pipes is justifiable. No expensive muffler. No expensive resonator. Just pretty welds less bends since its single to a y pipe. Literally a 600-700$ exhaust at a local exhaust shop. After a month on the car they will both look worn and the pretty welds aren't worth 1300$. Nor is the obnoxious volume (albeit thats my opinion as I've grown out of loud is fun) and the drone that would make me want to drive teh car off that bridge.

Wow, that is obnoxiously loud... Disappointed that this is the best HPF could come up with, definitely not appealing to the large majority of the customers out there.

Yeah that WAS me, I told you I was doing something a little different, didn't last long. Although I do have something up my sleeve that no one has done yet.

I can honestly say I know what you mean about the piping, BUT I did buy it used and on top of that it is a very nice product although yes it is just some bent piping. I really don't think any run of the mill muffler shop can make anything that nice. And sorry the drone isn't bad enough to drive my beautiful machine off a bridge.

Yeah I have to agree with that, I told chris they need to make something with a resonated mid section or 2 resonators in the back.

What are you going to do? Single straight pipe from the downpipes with no Y-pipe at the back? Install a 328i mtech Cf diffuser.....ppl would be so confused... "hey why is that 328i so fast????"
