Any shipping #'s for these?

 

Mine is due to be delivered today and I have the install scheduled for tomorrow. Should be fun!

 

 

Check your PM.

 

May have been asked but too lazy to read through the 13 pages...
For us quad setup guys, how would the results be if we removed the oval resonator and replaced it with this muffler?
Would the results still be the same, worst or better?

 

quads have been known to loose quite a bit of power so RPi does not make a quad setup. I do not believe anyone has tried to make a quad exhaust out of a RPi muffler as of yet. that would be an interesting idea though. If you were to do it, I would definitely do a dyno before and after to see if you gain/lose power.

Good luck

 

Wow, just stumbled upon this thread. What a steal! $799 for RPI exhaust for 545i and a free scoop! That's $200 in savings.....

Edit: Wanna run another special like this? I'll start the list:

1. Kaizen
2.
3.
4.
5.
6.
7.

 

535i axel back please?

 

there was no axle-back exhaust made for the 535i, just a catback version which is still available if interested
