Great cost Great cost, M5c sounds great with these.

Best all-around aftermarket upgrades! I think that VRSF is the best all-around company for car aftermarket upgrades. I've a BMW 335i E92, almost FBO (FMIC, Chargepipe and soon, Downpipe), all from these guys. The quality/price ratio is unbeatable! Well built products, great presentation and fast shipping. What more you can ask?

VRSF Charge Pipe & TS Raceport BOV Tiago's customer service is absolutely flawless. I asked if I could substitute the black version of the BOV for the blue and he went out of his way to make sure I got the one I wanted. Also offered a full refund on my O2 sensor fix for catless DPs that I didn't end up using/needing even a year later. Top notch. I'm a repeat customer and will be getting the remainder of my mods I want that are offered from VRSF.

VRSF downpipe I bought a downpipe from VRSF and it was perfect. It looked great and fit in perfectly.

Quality product...welds are perfect Quality product...welds are perfect, raw material used could probably meet ISO standards....sound is unreal. Running a catless DP with resonators deleted and wow. Not sure if VRSF knows much cheaper they are and how much on par if not better the quality is.
