The company that makes HT makes a lot of systems for other companies. Their in house operation is quite impressive.
The H gives more of the muscle car burble sound. The X smooths the sound and gives it a sports car sound. To me it's a little like my 72 Chevelle versus a Vette.
HT's dyno shows 18 HP gain on a completely stock Camaro. But, I'm not buying the notion of HP gain. Since I already ahve SOLO mids and Borla axleback, I'm not expecting any gain, just buzzing gone and a bit of sound change.
