I was talk'n to a guy a few days a go about trucks and he said something about a super cool downpipe . he said the end that fit behind the turbo is bigger than a standard 4" downpipe. does anyone know anything about it. I think he said he saw them on a genio's parts site . thanks

 

The MegaMouth. I got one. Makes a big difference in cool down times so it does work as advertised but damn is it pricey. I'm also not a fan of the fact that it's aluminum in this application. but to make up for it they Teflon coat it so that helps compensate.

There you go. Does no good when you have an aftermarket turbo. I'd save my money and put that towards a 35/40 hybird.
