Hey guys I passed by a muffler shop close to my house today, and they gave me a free estimate on my car. Turns out that they gave me two choices, Borla or Magnaflow, they're like $200 apart so no biggie. I was happy with the prices they gave me.
Now, the Borla exhaust I think gives a deeper sound which is what I'm looking for, but I don't want it to be annoying.
Another question was, should I go Duo, or Quad? They did say that if I wanna go Quad, I needed to find out if there was some type of battery where the extra duo was gonna go, or the rear right side of the car. I though it was just removing the plastic covering and voala. Do you guys know if there is a battery in there?
BORLA

Roger had the Borla on his 545i it sounded pretty nice actually. I have heard too many bad things about Magnaflow....voted Borla

I voted for the Borla, as I've always thought they were a higher quality product....I COULD be wrong, but that's my opinion!

Yeah at the place i can get the Borla Quad for $850, and Duo for $450. Installed!
what you guys think?

Come on, you heard how nice my RPi sounded at the meet!
Plus Borla has no proven gains, and the quad set-up will MOST likely rob you of HP.
RPi FTW! You'll be glad you did!
