ok all i just bought the zzp downpipe with the highflow cat....Now i dont have a header or the honed manifold, will this downpipe still fit to my stock manifold and my corsa exhaust??

 

If the corsa bolted up to the stock dp, I would think it will bolt up to the ZZP (because the ZZP can bolt to the stock exhaust)

 

yah but will the zzp bolt up to the manifold and im sayin stock manifold not the honed??

 

it'll work...

 

I have the ZZP header and DP with HF cat. All went well however the cat was rubbing on the stablizer bar causing some nasty vibration. Unfortunately had to modify the edges of the cat to make it fit right (hammer). Expected better fitment given all the ZZP hype.

 

 

so how far away is the bung supposed to be for my wideband by any chance would u all know this??

 

before the cat

 

lol i know its supposed to be before the cat and between 9 to 3 oclock...But i also heard that it was supposed to be 18 inches away from the head?? is this true??

 

Its nice to have it there, sometimes its not possible. You need to mock fit it then figure out where the sensor will fit. Its a pain but will save you a lot of headaches.

 

My ZZP pipe bolted up perfectly to the stock mani and a 2.5 catback . The welds are a work of art
