Hey all, just wanted to share a little information if anyone is looking for RHFCs because there is another option available now besides Fast Intentions. (FI is great, don't get me wrong!) This is just for those seeking options.

AAM Competition has updated their website to include a resonated version of their HFCs. As far as I know, I'm the only one running them on my car. They are 2.5" and have a 200 cell core whereas the FI has a 300 cell. Price is about the same between the two.

at this price point flanges should be stainless...

 

AAM makes some really nice products. What are you overall thoughts on fit & finish, sound, and performance? Any Cel?

 

Fit and finish are excellent.. only complaint is the welds were not smoothed out on the inside of the piping.

I have it paired with the invidia q300 which is the quietest cbe. When I added the rhfc, it increased the volume of the exhaust by about 5-10% and made it slightly throatier. Absolutely zero rasp of course with the cbe I'm using. Power gains were felt on my butt dyno.

 

You mean it was not back purge during welding process?

 

I'm not sure what that means, heheh... here's a picture though



I forgot to mention, no CEL.
