Going to pro-charge or do a roots style blower eventually on my car, doing the exhaust right now. Stock cubes, small possibility of going larger.

Do I go with 1 7/8 or 1 3/4 primary headers?
Off road y or cat y?

I would rather be legal, but if its going to cause trouble and consume power then It may not be worth the extra cost. I will for sure buy ceramic coated headers.

What do yall think?

depends on the size of the motor, an of course the power your shooting for..

If you don't want more than 450RWHP, just get 1 3/4. I have coated 1 7/8 Kooks, but I'm not concerned with limiting power .

LOL for 450 you could use manifolds. Honestly if you're only going for 450rwhp then throw a stoker crank in there to get 382ci and you'll have that or more. It would also be MUCH cheaper.

Couldn't 450rwhp be done NA with a good head and cam combo?

Yes it can, although you would lose some of your bottom end power. With an ATI ProCharger, gas mileage isn't affected unless you have a lead foot, and the car can still be used on road trips just as it was when it was stock. Obviously you could still drive an N/A 450 rwhp on trips too, but everyone's opinion of what they will tolerate for street use is different. Bob
