I am in the market to purchase both these exhaust items near tax season. Is there any way I may receive more information about both of them. They will be going on a 2007 Cobalt SS NA with an automatic transmission.

I've seen both items on Ebay.

Any and all help from a ZZP Performance member would be greatly appreciated.

 

What do you want to know?

They're good!

 

I have this exact setup on my SS/NA

ZZP Mid-Legth 1.75" Primaries Catted combo, and ZZP 2.5" 3 Chamber cat-Back. Best sounding setup ive had.

No rasp, Really quiet at idle and Cruse, but when you hop on it, she opens right up. I think I have a video

 

I have ZZP 1.75" Primary header and 2.5" downpipe with burnt cat and ZZP cat back with burnt out resonator and muffler

 

The main thing was rasp sound, but also which would be best header/downpipe setup, yes I do want the catted version. I will be installing new o2 sensors and any other needed parts when I have these installed.

I'm not concerned of HP/Torque gains since this is my DD and not used for racing or the such. Only other add-on will be the GMPP air intake.

Thank you again for any and all help.
