1 3/4" will work fine on cars up to 525-550 rwhp. 1 7/8" will take you from there to 700 rwhp. 2" is for anything bigger than that.
That being said...there are differences in design that will improve performance. Kooks for instance will be longer than the SLP's and have the merge collector, and venturi spike...so you may find 5-10 HP or more depending on how modded your car is. That is going from 1 3/4" SLP to new 1 3/4" Kooks.

And to the ***** that said it wasn't Kooks fault I ruined my ypipe, NO **** dumbass, I never blamed them. But since it was their ypipe, I figured that would be the people to call to look into getting a replacement. Hell you wouldn't call MAC if you broke your DELL would you?

If you go back and read, I apologized and edited my comments. I simply posted a comment and was just surprised. I'm happy that you know how to increase font size and use the bold function. No move on.

Because QTPs used the be the lesser expensive HVMC LT until now. Shoot, I'd have paid a little more for Kooks with HVMCs if they were close to the same price as the QTPs because of the leaks I have. They're better because I've packed the backside of the collector spike with manifold repair but I don't think it will last long; and DON'T tell me yours don't leak unless you've done some sort of pressure test on them. I was able to both SEE (I stuffed a flashlight into the backside of the merge collector and could see light through the spike) and HEAR (I completely sealed the exhaust ports and AIR ports, the 02 bungs, and pressurized the system and could detect and hear air leaking from the collector) the leaks. If Kooks has overcome this, kudos to you.
