I have a 91 vert with a freshly rebuilt engine. My question is whether or not this will pass NJ emmisions with a street port and a free flow exhaust? I want to put a header and presilencer on, but I don't know whether I should do it while the engine is being installed or wait until after it passes emissions (to save me $75 or so and a headache) to install the header/presilencer. Any ideas? The only reason I would wait to put them on is if I would definitely pass an emissions test with just the street port and exhaust. Thanks for your help...

 

hmmm, when you say streetport and exhaust, do you still have a cat in there? if you're taking it to a state run place (free) they would never pass you. and if you had a header on i'm not sure you'd pass visual inspection either (depending on how "motor oriented" the person is) the woman that did my n/a wrote down it was a 4-cyl!

last time i took my 91 n/a i passed with intake, Bonez superflow Cat, and Apexi N1 catback...WITH silencer in place. my friend took his probe GT with a small exhaust leak and they failed him for being too loud. so i dunno how loud your car is with exhaust and a street port. i'd guess louder than mine...

...but these situations have all taken place at the state run places with the rollers and *****. i dunno how a private shop does emissions and stuff...good luck...

 

i have a solution for you. get whatever exhaust you want but DO NOT take it to an inspection place. pm me for info

 

vosko, where in nj are you??????
im from ocean county

 

I would do the exhaust work after the inspection...unless there is a way to avoid an inspection. The Cats are necessary to pass the test.
