Another HP Question
I bought my C5 last Sept. I have changed my exhaust to the BB Bullets 
and I will be adding the headers and X- pipe in the spring. Will I notice a big change in power and how much of an HP increase will it show. Thanks for all your help

On a stock engine you would gain about 25 RWHP with long tube headers.I would recommend a tune after a header install You will feel and hear it.You should also get a C.A.I. With LT headers CAI, catback exhaust and a tune you should have about 350 RWHP.

More like 360+ with a good tune.

If you have an M6 you'll need to get a few more ponys more then a Z06 to keep up as the Z is around 100 lbs lighter and has different trans gearing with the M12. With an A4 you will need to get close to 400 rwhp with the stock rear end or go to 3:42s and approx. 350 rwhp.
After that the cars are close enough to equal that it becomes a drivers race. The A4 would have a slight advantage due to consistency.
