BMW 135i Custom exhaust upgrade for SBM15
The Riss Racing RHD catless downpipes, the C-pe catted mid section and the Titanium rear muffler on an Australian spec BMW 135i
135i rev then take off with RR DP's.
Car is bone stock minus the Riss Racing Downpipes. Hard to capture the difference in sound with my digital camera, but in person the sound is SEXY!
