This is a non incentivized review. This is for a 2015, EWG, i6 vehicle

Installation was not difficult. I was able to do it without any technical background in vehicles with rhino ramps.


I have had this downpipe installed for quite sometime now and have put over 15,000 miles on it without a CEL. I was looking for something that would prevent the smell but provide good performance and sound increase. I ended up installing my Borla exhaust before this mod and it did increase the overall volume of the car and it also added several more patterns of burbles that can be utilized via manual control of the engine using M/S mode for those of you who love engine and exhaust noise. This downpipe is rated at half of the OEM stock, 400 vs 800, and has more filtration than the others on the market, typically 200-300. Also, this downpipe is installed amongst of a host of other performance mods and I am without a burble or staged tune (I am only tuned to utilize the performance upgrades of my parts without adjusting boost). I recommend buying replacement flanges when doing the install.

If you're looking for the best of both worlds and you can't afford Fabspeed then get the AFE.

Thanks for posting that. In your OP, when you say replacement flanges, do you mean the Vband clamps?
