So I finally got around to installing my Bad-Mab header, 3" Hahn catted DP, and 3" ZZP resonated exhaust. I know everyone was saying 3" is overkill, blah blah blah. I actually think it is one of the deepest, throatiest exhaust notes from a Cobalt SC I have heard in person. I absolutely love the tone to it, no drone, no tone breaking when revving. Love it!
also I felt absolutely no loss of power to the wheels, the loss that everyone is gawking about to me has to be so minimal it is lost in the crank, if anything I feel signifigant gains in both bottom and top end. great exhaust system, just under 1000 bucks. and it sets ya up for future gains! I'll post a sound clip up a little later. thanks guys!

 

in for sounds!

hampshire is only about 25 miles from my area

 

Also in for sounds!

 

u won't notice it really by feel...but u will see it on the dyno...
but u will be able to add 2-3 * of timing....u can easily gain the hp back tweaking the tune for it...
a 3" exhaust is kinda over kill for a mildly modded car..but there is gains from it if u have hpt and know wat to do..

i have zzp 3" catback muffler only
zzp long tube header 3" catless dp

my car is stupid loud i can't even try to drive quietly
the exhaust aloud me to make huge gains on the dyno..

 

i'm an illiterate mexican....i saw the word exhaust and hoped for vids

 

I'm not Mexican, maybe slightly illiterate, but i hoped for the same thing. lol.
