ive been trying to search but couldnt find any real answer.
i have an 08 535i with the rpi exhaust. i love the exhaust, but recently changed up my bumper with the m5 rep. i hear people saying put dummies on the other side, and theres others who use the stock exhaust and make custom piping. i know umnitza sells the exhaust but its never been fitted on a 535i.

i just want to hear more opinions before i make my final decision. any inputs or pictures would be greatly appreciated.

 

Regarding the "dummies", it would look silly if the exhaust is only coming out the driver side on a cold morning. :thumbsdown: Also, I hear quad retrofits can also rob power.

Hang on just a little longer

thank you!
now im debating, basically everyone is doing custom piping on their stocks or aftermarket.
i can do some custom piping on the rpi that i have. "as much as i think its wrong to destroy the "perfect exhaust for the car"....
so my options would be
sell the rpi, get a magnaslow and basically have $0 in my pocket
or make a custom with my rpi and shell out a few hundred bucks
or sell the rpi and custom pipe the stocks with a couple of hundreds in my pocket
does anyone know if something were to happen..say hpfp or any mechanical problems. can they blame it on the custom quads?

 

why not just sell your rpi exhaust and buy a custom quad remus set-up

 

I went with a magnaslow and I'm pretty happy with it.

 

+1. honestly if you were to go quads, best to go with a custom setup.
