Long tube Headers for 94 Z28
I installed long tuber headers on my 94 Z28 and made a custom y pipe due to my convertible cross memeber. I eliminated my cat and ran 4 inch exhaust pipe to the muffler. I had to but 12 inch O2 extentions they cost about 15.00 a pair. I eliminated my EGR system with blocker plates and the air pump you have to program all this out of the PCM or your SES light will be on and you'll run rich there were 5 codes pulled on my car when i installed the headers. I also have problem with the collector on the drivers side bounces on the floor when at idle. I notice a big performance difference after every thing was programmed I used Scan CAT to program my PCM

hey question tho, i got a 95 z28 and wanna put pacesetter longtubes on. ground clearance not an issue but about emissions do i still have them? even if i did, the O2 sensors are before everything and the new pacesetters come with the O2 sensor plugs, so do i need to worry about anything?
