Got the LTHs installed last week. Was very surprised with the difference in power in the car. Had GTM Res. Test Pipes before. There is alot more power up top now and I definitely need a tune bc I know I'm having to shift with more power to spare up top. I was also surprised with the difference in sound. The n cabin sound I was a bit disappointed with, It seems as if the exhaust is quiter inside but from outside the car it has become quite a bit louder. I love the sound and wouldn't trade my setup for any other. The video has take-offs, drive bys, launches and fly bys and some 5k revs at the end. The launches aren't very clean bc of traction issues due to a poor road surface and the power I'm now making with the Nismos already poor launching abilities. Enjoy
