I sent a pm to the CED guy on here and he said he had the week off and didn't have a way to look them up, so does anyone know what size primaries are on the honed exhaust header and what is it's exit diameter? Also what size is the Touring exhaust? is it a 2.5"? i need to know so i know what size downpipe to order.

 

Touring and Performance exhausts are both 2.25".

 

Don't go bigger than 2.5" or you will end up with a leak. Or get the ZZP ones with the smaller exit, but it doesn't flow any better than a full 2.5", the smallest point is still 2.5".

 

...and the manifold is exactly like the one you have on your car now, but a little smoother.

 

just get a 3" headerback exhaust

 

Thank you for your sidebusting, its greatly appreciated...NOT. theres a reason i'm asking this question *******, cause i don't want to go full 3". i don't feel like spending the money to mod it that far to have the need of the full 3" exhaust. And if i did, i wouldn't be asking this question now would i...more than likely not.

 

Yup they are both 2.25 which is the same size as the stock exhaust. I have the GMPP Performance exhaust and its awesome, you also will have to buy a tip for it as it don't come with one either angled or straight.

 

yeah i know haha, i was just trying to find the size it was so i know what size downpipe to get

 

if youre keeping it under lets say 250whp go with 1.5 primaries on the header and 2.5 downpipe and catback. 300whp get 1.75 primaries with the same setup, anything above that it should be fine to go with 3"
