Rpi, full exhaust system, sprint booster question/advice
Sup guys !

i have been searching on google but cant seem to find the straight forward answer. Is there an RPI exhaust system (full system, not just axel back) for the 530XI AWD??
If not you guys recommend any other brand that would allow me to gain hp? Ive seen them available for a 530i but these arent for the XIs. Anyone with info please advise... Also anyone with bad reviews on the sprint booster or rpi scoops? Im wondering if i should add those mods to gain hp as well

Also can i do 19x9.5 et 40 front and 19x9.5 et 33 rear?? Will this provide a more "concave" look even though its a square set up?

 

RPI's exhaust has been put on an XI model, but there is no full system offered, only the axle back which has produced gain. The scoop which we also have in stock has also produced gain. As for the sprintbooster, that unit does not actually provide a hp gain to the wheels, its function is to increase throttle response electronically.

 

Thanks !! Im gonna jump on the rpi exhaust as well as the scoops. Is there a lot of drone with the rpi exhaust? Can you give me a price quote and a link to the rpi exhaust?

 

I just installed the rpi on my 530i i barly hear any drone i guess im still young i think i need to go louder and chop off my resonator LOL

 

How much did you pay if you dont mind me asking? Rpi + install?
