Just got done last night installing my GMPP cat-back...The thing was a breeze to install...Mind you I have NEVER done anything to a car but it is very self explanitory. I took some video and pictures of doing it and once I get some time I will get them posted....

The thing sounds awesome too...Not ricy at all. Again once I get some time I load up some good before and after sound clips....

As far as performance go I did not really notice an increase for the in town 40 MPH driving, however I did open it up on some back roads and once I got in the 4,000RPM range I did notice a little bit of difference....A little more Power. I am definatly happy with the purchance.

 

Congrats, I love my GM catback as well

 

Congrats. Mine will be on soon enough! I love the GM exhaust sound.

 

really guys is this a good option? im looking for an exhaust for my girls 06 ls, and we HATE fart cans....... i want something that sounds deep, i know its hard to come by for a four banger, but please do get thoes clips

 

ok guys i have CTS and i know alot of guys opver on my forum have been adding on the CTS v exhaust to the reg CTS, adds some power but nice grumbble, and the best part is most of the CTS V guys sell them for 100 bucks casue they are just taken up space, now my question can this be done with the SS to the LS..... ?

 

yes but you would most likly have to weld the ss exhaust to the ls...in ordered to get the stock exhaust off you have to cut it...go with the gmpp its got a great sound..really deep not ricy at all

 

No rice at all..I drive an american car and refuse to put rice on mine...hehe...I will have the clips up this weekend...

 

I could not be more satisfied with the GMPP Sport Catback. The thing makes me want to drive my car for hours.
Also Tom at http://crateenginedepot.com will run another group buy on these pretty soon. Keep an eye for the awesome deal.

 

word... so it is possible to put the stock SS on just some welding, same for us CTS boys, hmmmmm i wonder how that sounds, what is the size on the stock SS, vs the Size on the Gmpp

 

was it the touring or the sport gmpp?

 

here is a direct comparison of the stock and gmpp exhaust

performance exhaust''

 

I got the sport cat back...I know the feeling of wanting to drive for hours because I left work today to go pick up pizza for our group just so I could listen to it...Its like a brand new car again...

 

Yeah, when I had mine put on (a saturday) I drove seriously, for about 3 hours just listening to it. It's that good!


I'm happing with it. Nice rumble to it, not ricey at all, has it little backfires/pops every now and again. I love it though!

 

can we get some 2.2 vids, preferably w/ some fly-bys

 

yeah i would also like to hear the GMPP on the 2.2 does anyone have a soundclip ?

 

I will get some fly bys tomorrow evening up...I will be going out to my moms in the country to record some...I have a 2.2 so you will know exactly what it will sound like..

 

 

I'd like to hear the GMMP touring version because everyone seems to have the performance version and if I ever changed the exhaust on this thing it'd have to be relativly quiet.

 

they sound the same except at speed the touring is under 90db where as the performance is over 90db

 

Oni...not to bash you but thats not the best vid...did you take it past 4krpms in the vid?

 

course werent you watching? we both did high spead 1-2 shifts in each comparison. it isn't some fast fly by, we were comparing the daily drivability of the exhaust. I cut the volume a bit cus damn if I hadn't you woulda thought your speakers were too loud.

in the last clip I didn't launch fast cus I saw a cop and thought I shouldn't go to fast but the cop had a talk with us anyway and we got kicked out of the park we were at.

 

Cool, I wanna hear it now because I would want it as quiet as possible. My first car was a '91 eclipse that my borther had before me and he put a fart can on it and the interior resonance drove me insane not to mention I'm not fond of the sound of a 4 cylinder.

 

congratz on the new toy

 

As promised...Here is my quick vid of the GMPP performance catback on my 2.2.

Now remember this is the ONLY MOD that I have on my car so all you are hearing is the exhaust...Enjoy!!!
