i have a full vibrant exhaust and my cat took a **** on me... i need to pass emmissions this month so im check into just buying a new down pipe... im looking at zzp but i dont know if it will bolt up... the pics they have on the web site look like it has the stock gm flanges and i dont want to have to put on new flanges just to get it to fit... any help would be great thanks!!!!

 

Bump.......

 

Order the flanged ZZP that is the direct bolt up. It will bolt up, and then have someone with HP Tuners just eliminate the second o2 sensor. The thing is just a pain anyway.

 

Thanks
