Man… listening to all of those exhaust clips are depressing. Only good thing about a 2v, they sounded amazing whend one right. Really thats the only downside of the lsx motors they don’t sound nearly as good. My mustang sounded soooo deep, these all sound like tin cans.
Also, loudmouth and loudmouth II’s sound completely different. Loudmouth’s sound like garbage on all cars, the II’s sounded great on my mustang.
Sounds like a tin can in my opinion… 
I guess i was spoiled with the sound of my old car. Honestly I dont hear too much difference between the LMII’s and the spintechs from what was posted.
