I do like that you dont want it tooooo loud, but your still going to be louder than stock if you want to get any real increases.

Dont know what ones you have checked into yet but most without quiet cores will give better performance results and gains, but also be louder.

Still some are louder than others and some of the ones I like that are not overly loud are most of the disc types. Those would include the supertrapp, WB, FMF and even some of the builders (CT has the larger style supertrapp) and what I like about them is that you can adjust the actual exhaust size by changing the amount of discs.

Personally I tend to lean towards the ones with the reverse megaphone since that seems to work well for the much louder builder pipes (the CT and FMF have it, not sure on others) and all the "shoot out" winners in the magazines I can remember had that stye.

If you do some research you may find you dont need and maybe dont want to bother with a header on the stock engine. Many people dont believe you see a good gain for your dollar from it on a stock engine, and even some feel the same for a modded one. I know TC racing recomends using the stocker even on their stroker engines so maybe there is something to it.

Hope that helps.
