For anyone else with a 2.2 considering their exhaust options, I just finished installing all of mine today and it sounds like sex...no rasp, very nice and mellow tone at idle, when you romp on it, it sounds great.

ZZP 1.5" primaries header
2.5" DP w/ highflow cat
GMPP Touring exhaust.

All total to CANADA it cost me roughly $1000 for the works after shipping fee's.

 

Sound clips or ban :P

 

Cool, I had great results with a ss/sc header/stock cat/Tsudo catback

I plan on getting a 2.75" cat off of a minivan and getting a custom downpipe. with it welded in.

 

I plan to do a soundclip as soon as I get something worthwhile to record it with..will be soon!


I was moderately pleased with the SS exhaust, but the gmpp is so much nicer imo.

 

i have a vibrant header and dp with a megan racing exhaust, the sound is perfect

 

I have the tsudo catback, and I just put my zzp header/dp combo on it and it sounds amazing, just thought you should know that lol. Burn the minivan after you take the cat off...

 

are you talkin about the shorty or midlength zzp combo?

 

zzp combo

 

yea is it the shorty or the midlength?

 

Nice.... I have my GM set ready to go.

GMPP Intake, 2.4 intake manifold, SS exhaust manifold, SS DP, GMPP Sport Exhaust

 

Didnt know they made a shorty "combo"? Anyway, its midlength

 

do you 2.2 guys see any difference in performance or gains with our header and dp?? jw cause i hear a lot of people do it.

 

^^^from waht i hear its really just a little... maybe a few hp here or there just by freeing up some of the restriction in the exhaust

 

sound clips

 

That's good I'm glad you like the sound
I had the xtc 2.5" Dp with Highflow + GMPP Touring and I hated the sound.
It sounded good at idle but when I hit the gas it sounded like a combination of a weed wacker and a dirtbike

 

Were you running a header then? or the stock manifold?

My sound is a constant mellow tone that gets louder, but keeps the same tone as you get on it...none of the bee's in a can **** heh

stay tuned

There is definitely a performance gain from stock. Exact numbers I dont know.

But, as proof; my gf drives a bone stock 06 g5. When I had just my intake, I couldn't gain any ground on her when we did a few runs on a highway. The day after I finished installing all of the exhaust parts, we did it again and she couldn't keep up...I kept pulling further away from her...so the gains are there for sure.

 

I was using the stock LSJ Exhaust Manifold at that time.

 

I guess the midlength header/dp is making the difference then.

 

my plans have been almost the same for a while. i have the zzp header dp sitting in my room and im ordering the gmpp touring tomorrow. the only thing is that im catless so it will be louder, but hopefully still not raspy.

 

i've got the zzp combo wit 1.5 primaries high flow cat and megan drift series cat back and it sounds great and the car pulls so much better now too.

 

i got a custom exhaust that has a high flow cat n exhaust by magnaflow. it sound mean not a rice out car. the full exhaust gets a few hp but once u get the tune you will feel the difference n power.

 

My tune ships from Trifecta today!

 

Good to hear...thats the exact setup im interested in doing...I just got the ZZP header/DP the other day but im gonna wait til i buy the Megan exhaust and install them at the same time...Do you happen to have any videos with the setup on your car?
