Ok, Im thinking to get my BMW a new exhaust.
I am looking for performance gains and also a nice sound.
We dont have Rpi suppliers here, so its kind of costly to get it from US. Thats why I am looking for something else
Wondering if custom made exhaust - a straight pipe exhaust, called cherry bomb I assume... will deliver same or closer performance and sound of an Rpi exhaust?
I have this kind of custom exhaust on my other car and its great.
What you think? Will this work for an e60? Or I should look for something aftermarket like Rpi, Eisenmann, etc. ?

I have Cherry Bomb quad setup. Single sided Cherry Bomb muffler, I have no idea.
Are you going quads? If you are, you will lose power. Members that went quads lost power.

no, i dont want guad.
So how is you cherry bomb? Is the sound nice? Performance?
And by the way, does Rpi give estimated figures on HP and torque gain from their exhaust?

Video of the exhaust
RPI is proven gain tested on a dyno. Don't know the numbers.
