Exhaust System Inspection

supra_91 · 10-04-2005, 01:51 PM

it is the resonator. if u take it out it will make your car louder. i took mine out and put a 2 1/2" catback exhaust of with a straight through muffler and it sounds awesome

A resonator huh. OK, sounds useless. What exactly is a catback exhaust? thaks for the help

it is pretty useless...its there to keep the car quiet...though i think you might need to put it back during state inspection...because i think in jersey ur required to have them

a catback exhaust is when u get new exhaust piping from the catalytic converter on back and a new muffler

don't they only check your car for emissions once in a lifetime

I think in Jersey they check emissions every 2 yrs. I get inspected this December, so after that I will do some exhaust upgrades and be ready for the summer, ha ha. should I replace the cat with a performance job? My A-hole friend said he could clean my engine, but after he did it needed to be dried so he revved the engine to a point where I saw the cat get red hot. I mean it turned red. Do you think that ruined it. (I will never let this person near my car again) I got everything back in order and it runs great again idling at about 800 and taching out at about 3500. Any suggestions on exhaust upgrades. If you install a header do you keep that heat shield on? Thanks in advance.

yea jersey inspection is every 2 years...i just saw that u live in kearny.. i work in elizabeth and i go to skool in hoboken...and i live around morristown haha so im close by, as for the cat...they usually turn red...well orange when it gets hot since the exhaust gas that exits is also pretty hot, though i doubt that he ruined it since these things are designed to take a beating, if you have an aftermarket exhaust i recommend upgrading the cat to a free flow.. or leave it stock...its really up to you..as for the headers i ditched the heat shield and instead im using heat wrap...i think its better than the heat shield, i use the wrap from design engineering...stuff is pretty good

you can either go to a muffler shop and get a custom exhaust put on or you can get a hks or blitz exhaust

i think those are the main ones that they make
