i have my 525i with rpi exhaust, here is what s on my car.


i had ordered a crossover x-pipe, i need better torque.

what is the question tho? do you want to leave the resonator when you install the rpi exhaust?? if ordered the axle back you just need to cut the pipe and leave the resonator
and use the clamp that goes with your rpi no need to weld...
hope this helps

I think he's asking if he should keep his resonator. I am assuming you are getting a custom x pipe fabricated and need to know the dimensions to either include or exclude the resonator? He already has installed the RPI, but wants to install an X pipe and either keep or get rid of the resonator.

I don't have much experience with your model, but if someone with experience in this matter cares to speak up.....

Good luck.

yes Kaizen, u are right.
i already had my rpi exhaust installed. but i feel the torque is little lose.
so i want to know if it is better to get rid of the resonator when i install my x pipe or not. if get rid of the resonator, i will have to put in a y pipe as replacement.
it is just a normal crossover x pipe, the brand is GP X-Pipe.

thanks anyway, i wish someone can give me a hand.

i did weld it instead of clamp.
the factory side is smaller, and the guy who install for me said weld is better to eliminate the air leak.
