We have just received RDSport's latest product for the current BMW M5 and we are looking for a test car to do before/after install dyno testing, as well as sound clips and install photos. Expected (as stated by RDSport) power gains are 21HP at the crank, and 22 lbs./ft. of torque.

MSRP for the entire system is $ 8,028.00 plus 8 hours install. This is for the downpipes, metal race cats, x-flow downpipe, and rear silencers. The test car will receive the whole system installed, with before and after dyno tests, for $ 6,600 out the door (OC sales tax included).

If you are interested, please e-mail us at info@italiantuninggroup.com or call us at (714) 970-2800.
