I've had experience with Riss Racing's 200cell HFC's and it took away the smell 100%.
MrHarris, Where are the Riss Racing HFCs located in your exhaust system ? I have an E93, and I want to get Fabspeed HFC and resonated X-pipe. I will mate this to a Vangaurd axle back. I can't remember where I read that placement of the HFCs is important to exhaust smell, but I recall reading that. My dad has a 1955 Chevy. It stinks up the whole shop. I really would like to aviod the stink bomb effect.
