I heard good things from the euro forums. I like to try new things. So why not. I think the pipe might be more well suited for my metra set up since the metra has much more torque and the gila is all rpms. We'll see. I still have a lot of tuning to do. Might throw the simo on and see what happens.
Could probabaly gear really low and hit high speeds, but I don't know if I want to put those kind of rpms on my crank and bearings because I know they can't handle it for too long.
