I just wanted to let you all know that I discovered what my problem was with my car. If you dont remember, my car had become VERY VERY quiet, more quiet than it was when stock and it was the same performance level as a near stock SS/SC. Well today my new GM downpipe came in and when my mechanic pulled off my old downpipe he tipped it up and a huge pile of stuff came out. From what we could tell, the front of the cat broke apart and got lodged in the back half of the cat causing it to clog VERY BAD.

Well needless to say with my new downpipe my car sounds like sex and runs better than it ever has. Also, I went back to my stock spark plugs and the car runs GREAT with them!

I also ordered a Midlength ZZP header/dp combo and it should be here in a week or so according to ZZP.

I just wanted to give yall a update!

 

nice man enjoy your new found power agian lol

 

mine was doing the same thing, when i bought it that is, just running like dog ****, so i revved it up a little bit, and a chunk of carbon and insides of the cat came flying out, and it runs a lot better now, but im still redoing the car, so i still need a new cat, but it might still be under warranty, so thats even better

 

catless ftw

 

Nothing beats a nice flame every time you shift at redline!

 

yes lol

 

glad to see you have solved your problem.....what the hell kind of cats are gm installing on these balts? freakin crap

 

i think my 2nd one has taken a **** also..... no cel yet though

 

Good to hear you have fixed your problems.

 

yeah when i bought it also, there was no CEL, i currently live in nebraska, and we dont do emission testing here so, im kinda thinking about going catless, what do you guys think of the catless, and who all makes them

 

go catless

 

ZZP makes downpipes.

I personally just gutted my stock cat. Worked very well.

 

how does it run when you go catless tho, does it throw CEL codes at all, any numbers on catless compared to catted

 

are you stock? have you had any problems in the past with your car?

I would like to know. Mine seems a bit weak lately.

 

im all stock right now, i actually bought the car wrecked, really easy fix though, asi am a a body guy my self, it is a salvaged title, but only 12,000 miles, so its all stock right now, but i figured since im going to be needing a cat anyways. Granted i might just get it done free from warranty, but we will see, when u can get more gains doing something else, y not right?

 

the numbers are maybe 1~2 whp at best and it will make a cel

 

no **** that is it, i guess it is probably understandable being the hi flow cat, pretty much are free flowing anyways arent they

 

hi flo cat is fine man stock one is bunk

 

when i do my catback install maybe i'll start it up open downpipe, and see if i can blow some **** outta it LOL

 

yeah i will probably just go hi flow then, it will be to much of a pain in the ass, for the catless anyway i can imagine, plus the CEL is just annoying when it is always on

 

hpt is a good thing

 

GM puts warranty blocks on all salvage title vehicles so i'm not to sure they will warranty the cat . Good luck thou .

 

I had been suspecting a clogged cat for some time on my car due to how quiet it was. I have the same exhaust set up on my balt as a very close friend of mine and I got my exhaust 1000 miles before him and from the day he put his on it was louder. What sucked about my cat was that the front of the cat broke apart and got lodged on the back half of the cat so it couldnt free itself and go out the tail pipe, thus causing extreme clogging.

Also I found out that we share the same downpipe as the sabb 9-3. When the parts guy handed me my DP it was all stickered up with sabb stuff. I thought it was pretty neat. Anyways, I just got back from alittle cruising and I cant believe how good the GMPP sport cat-back sounds. It sounds amazing for a 4 banger.

I cant wait to get my header and catless DP!!

Thanks for all the kind words guys and gals!
