Last wednesday i installed my GMPP honed and extruded exhaust manifold and GMPP performance exhaust system.. i was wondering if anyone had the same set up or something similar and what kind of numbers should i be expecting?? Either at the track or on the dyno?? would appreciate some feed back, thanks.

my best run on 1/8 was 10.103, with intake only.

 

what model do you have?

 

06 Ss 2.4....

 

project looks clean thats how i have to put on my exhaust just jack it up i dont have lifts so its gonna be a bit difficult. but its all in pieces so i think it should be no prob. how long did it take to put on the exhaust and header. cuz im doing full exhaust myself header DP and exhaust in an afternoon hopefully.

clean job. howd the install go? can u get my a sound clip or vid. i wanna get the same setup.

 

I can't tell you what to expect for numbers or track numbers. However I bet it sounds sick. How was the install for the manifold. Any tips for me, going to do mine next week.

 

the whole project took about half a day ... had a little bit of difficulty pulling the stock exhaust off ... you need to get both the back and the front high enough to have room to pull it out ...

the install went well but we did have a few problems.. ill try to get a clip of the track or a sound clip....

 

oh ya ... your right, sounds dope ... has a deep tone and a nice gargle to it... but not too loud .... i can still here all the air getting sucked up by my injen cai.... just be carefull with the studs from the manifold to the downpipe .... i actually broke one and was running it with only two untill my new one came this past tuesday... i could hear a loud buzzing noise when i gassed it because the two studs werent enough and air was leaking out.... i would suggest to order three new ones just in case you break any of them ... and use a lubricant to remove the studs and the o2 sensor to make it a little more easier....

 

yeah thats why im glad i have lifts took me 45min when i did mine
