I purchased my dc sport header (4-2-1 ceramic) two years with plans of changing the collector and just never got around to it. I've done some searching and some people have mentioned welding on a megaphone collector. Does anyone have an idea where to purchase basic megaphone collector piping? Or would yall go with a basic 2.5 inch collector? Any opinions would be appreciated.

 

anyone?

I modded my collector with a 2.5" pipe and I noticed significant gains after I got it dynotuned.
