I'm going FI and I was highly recommended 2.5" by exhuast guy. I was running 3" Turbo back on the DSM but was that was 500+hp.

I run 2.5" exhaust. Seems fine to me, I'm gonna wait till I have a couple more mods to add to the list before I send my PCM to Black bear to be tuned again and then Security Relearn and shit once again.

If throwing a straight pipe in instead of the cat caused engine problems, then I think my kon would have died well over a hundred thousand miles ago, as far as I know the CAT on this truck was removed many years ago...
I did the same thing to my old cavalier, no problems at all, if your somewhere they test emmisions then you can get in some major sh*t but if you live in the same kinda location I do, then go hog wild lol

Exactly. My cat was already cut off well before I bought my truck. The guy I bought it off of is friends with my mechanic and goes to him for all his car troubles and what not, so I know my tahoe has always been in good hands, but he cut it off at around 100k miles. I just rolled over 150k and she's still running like a champ, cat-free.

No South Carolina stopped inspections over 10 years ago. So i do believe i am going to be Catless this weekend. My Engine light stays on 24/7. I went to AutoZone and scanned it. It said both O2 sensors bad. My Yuk has a new crate moto and from day one it skipped BADLY. So i took it back to shop, they said they thought it was bad gas, it had been sitting up with blown moto for 2 years. I put seafoam and high octane. Same results. So back to shop. When i got her out, the bad skip was now a very little skip. Especially take off and WOT it'll bump bump or skip skip a little just enough to be agrevating. Take off it seems to stammer then go. I asked the mechanic what was wrong and he stated he had to tweak things here and there. If it still wasn't to my liking bring it back. So i did, then he stated i needed to replace quite a few things, 02 MAP Plug wires cap roto and so on. Then my skip should go away. All of my stuff is original never been replaced so its prolly time. but i first want to start with cat and work backwards in a sense.
