Has anyone else tried to post the word "s h i t" because i had to put the little * thingy to have it post it...PITA!!!

Yeah i but in two 25 inch sections where the packs where. its loud but sounds great.

Not to hijack this thread or anything but you think if i added 2inch piping on vortec 350 it will crackle more?It has shorty headers,no cats,2 3/4 downpipes,2 1/2 after that then 2 1/4 tails.

when are you putting in the 2 inch pipe, straight after the shorty headers i'm guessing?

 

[GMstrong]

I was going to put it after the 2 3/4 piping.But now im replacing the downpipes with smaller piping 2 1/4.

I would think it would, but as I said before, i dont like cackling unless its when I romp on it really hard.

Well, Im not very happy. I gutted the convertors and then plugged the O2 holes and strapped the sensors up. I was told that the downstream sensors would be okay if you tied them up into fresh air...this must not be true on Vortecs(97). I hooked it up to the scanner and it shows low voltage on both downstreams. Also all of my fuel trims were very high(110-120) so its running very rich. Who has the solution?!

Hopefully you didnt unplug the ones before the cats.

Tune. Get a custom tune and have your tuner tune out the rear O2' sensors.

Haha I'm pretty good on cars I know which o2s are downstream...and what tuner do you recomend?
