Their justification in price for their catback xpipe solution is that it negates the need for headers thus saving you money horsepower gain wise. The one guy that has this setup never disputed those gains so I was like ill give it a shot as I wanted header performance without actually having to change them.

I can’t imagine how you would get header performance with an x pipe and exhaust. The engine will still be restricted at the manifold. Don’t get me wrong I believe there is power to be made, tho I don’t believe it would be much.

I just saw this set up on someone's Instagram. It's shiny. It looks like 2 smaller suitcases in line with each other.

I'd love to see a mythbusting apples-to-apples dyno comparison with this axleback versus a few other brands vs stock on this platform. None of that "it made 20hp but dyno conditions were different" crap. I mean, I know what the outcome will be, but it will end the debate.

Well by all means put it on your car and find out. If it didn't make those numbers oh believe me, I'd be real about it. But since you have clearly had the exhaust on YOUR car and put it on the dyno, please tell us what YOU made since you apparently are a living dynojet!

I don't have any personal dealings with them, but rumors are out and they are coming in fast n furious. I'd stay away. They want $6k for their TI exhaust systems. lmao. Stop it.

LOL! But seriously I doubted the vendor dyno gains numbers myself until I was proven wrong.
