I am looking to change my exhaust system. I want to go with the ZZP header and dp combo with the ZZP cat back exhaust. The only problem is that any mods to my exhaust cannot be louder than the original exhaust. I have heard that it is as loud or even less loud than our factory exhaust. If any of you have this set up could you please chime in with what you think of this system. Thanks! :)

well i have the zzp header/ dp on the stock catback

that has in cat pulls before and after as well as some outside revs... disregard the noise that doesn't have anything to do with the header dp lol

i think it's pretty close to stock sounding you probably wouldn't get hasseled for it

Thanks man. I'll have to take a look when I get home from work. I had the GMPP performance and loved it but it was to loud for around here. Did you notice any gains?

yea i got the setup for the lsj 1.75" primaries and 3" dp with HF cat and 2.5" bolt in .. even though i'm a 2.4 as i plan on going procharged and it seems to pull hard as you go up the rpms sounds nicer breathes nicers and my tires hate it lol

It sounds better with the ZZP combo. Even with the stock exhaust. It does not sound as harsh.

i know i'll have a clip of it with an after market exhaust.. however it's the tsudo.. and it might sound beastly compaired to your silly gmpmpp :P jk man
