Okay I've went ahead and set a goal of around 600 rwhp for my street machine/cruiser. I'm planning on using a Kenne Belle Blowzilla kit. But before I buy it, since it'll set me back a bit, I'm upgrading the exhaust. I've decided to go with long tube headers 1 3/4" with 3" collectors, a 3" off-road mid pipe and a 3" cat-back system. The questions floating around my head are: will this whole 3" exhaust cause back pressure problems until i get my blower?, if I swap my plans and get the blower first will the stock exhaust suffice? Take in account that I won't be hitting the full 600 at first either cuz I'll have to rebuild and also the first pulley for the blower that i'm getting will only be 8psi. I stated the 600 HP as my eventual goal nothing else. Any help or insightful information on this would be greatly appreciated. Thanks in advance
