Header addition ? power I had asked about the Flowmaster cat back, which did not sound like it would do much good. So I purchased a set of Mac headers and Y pipe to go with the Flowmaster to make a whole system. Will that help the flowmaster to any good or will how much will my sytem help the car.

Re: Header addition ? power Depends on your other mods. U should be getting 25 to 40 rwhp stock. I got shorties which are less efficient and I got 27 rwhp w/o cats and w/ Hooker catback. When I was stock.

Re: Header addition ? power The only mods I have done so far is the TB bypass, opened the air box, K&N, and Hypertech programer. Hope to get a rear end with 3.73 and stall this month before I start on the engine. I have only had the car a month so I have to hide the money I spend on it from the wife , but I am doing the performance work as fast as I can.

Re: Header addition ? power I know what u mean, I'm sure one day u will hear "U love ur car more than me".
U could get a 100 shot NOS before your TC and gears (I assume u have a GU5) 3:23. It's cheaper and only used when needed. Also with 3:73 ur MPG will hurt a little more. Get bellows, pullies, ported or GMAF.
Get your car on the dyno to be able to monitor your gains and have a baseline for the future.

Re: Header addition ? power I have the 3:23 but I was afraid the rear end would not hold up for long. The shop told me if I do the heads and cam I did not want to use the nitrous with it. The nitrous is one of the options I wanted, so I am trying to decide to go engine route or blower route. Susposedly it is not good with the engine work to put nitrous or blower, I do not really know.
