So I got my Vibrant header/dp today and I was pretty excited, then someone was saying how the Vibrant header/dp with GMPP exhaust wouldn't work. Major buzzkill haha. Some people are saying "good setup" others are saying not, I want some clarity. Thoughts?

 

cant see why it wont work. vibrant header/dp is designed to bolt to the stock exaust, gmpp is designed to bolt to the stock downpipe. should work just fine.

 

It should work without any problems.

 

It won't bolt straight up... and 2 you are going from a 3" downpipe to a 2.25" exhaust... so you have a very expensive 2.25" exhaust system!

 

yeah.... ur going from good flow from ur header and downpipe to shitty flow in ur 2.25 GMPP catback. u should atleace buy a 2.5" catback.

 

I understand the whole size/flow thing, I just want to know whether or not it will work. I've spent the money on the parts and I'm just looking for an answer. They're not permanent, I can always go back and change them in the future...
Anyone have the combo?

 

it'll work....u just wont get as good of a gain

 

Okay, thanks, that was my question. I'll sacrifice some gain for now. If I like the sound, I'll stick with it, if not I can always change it. It's more for sound anyway. And besides, my flux capacitor should be here next week so it'll more than make up for it haha
