Just wanted to give you guys my opinion on the SCJ manifold that I installed a few days ago! So I got the SCJ manifold, the twin 65mm TB and the FRPP CAI. Now I researched many, many hours about this manifold. Some people said it wasn't worth it, you need to spin it to 7800, keep the stock manifold blah blah blah. And some people who actually have it installed love it. Well I decided to try and it and WOW. The second I got in the car I felt a difference, no torque loss what so ever as well. For a comparison, I raced my buddies '13 GT with the same mods I had before the manifold install.. longtubes, o/r x, Cai, tune. We were neck and neck the whole time, we were both on 93 as well. After the SCJ manifold, I just keep on pulling and pulling on him. I couldn't believe it. While he was shifting at 6800-7k I kept on going to 7500 and left him in the dust. So does the manifold make a difference? YES! Just wanted to share my opinion and thoughts about the manifold. So far I am VERY happy with my purchase and haven't looked back. And my tunes are from Shaun@AED. If you guys have any questions about it please don't be afraid to ask! I'll be happy to answer!
