how many cats does my 98 rango have?
and if i happen to remove it? MPG goes up or down?uno.
alright thanks,prolly down. but im not sure. have yet to do this and prolly wont.
if i do straights i will lol. but i need to know the effects of removing the cat first, cause right now i cant afford any less gas mileage that im getting right now.so u want a straight pipe? lol. take videos!
but just remember...u remove the cat and ur dur wont meow no more.
oh haha what a comedian :funny:ur removing the cat....no cat=no meow..
and the only thing is u might get a CEL for the o2 sensor but i think on the 98-00 u can just ziptie it to the frame.
shhhh i knew that :rant:CEL=check engine light.
only thing i can tell u is to remove it and replace with a pipe and if u get a cel or lowered gas mileage put it back in.
there shouldnt be a CEL as long as u keep the o2 plugged in and not just remove it with the cat.
back pressure is a myth. stop believing it!i say keep it on if your already straight pipe all the way back with no muffler, your going to need backpressure. Also It will sound really loud, which may be cool to you at first. But after driving it alot, you may wish you had not touched it. I have no cats on my durango but I have a 28" long magnaflow muffler that quiets it down. I got tired of it being so loud when I had the flowmasters. I also have a cell on with a check engine light. As far as gas mileage go concerned, I did not see any difference.
true, cats can plug up over time, but really they shouldn't unless you're either burning oil and your exhaust is full of oil smoke, or if your tune is excessively rich. a slightly lean, and very hot exhaust will burn that crap out and keep the cat clean.The problem comes when cats get clogged, and they will. I'm redoing my exhaust, build in sig, I'm going to have the exhaust shop mfr from the headers to the flowmasters. Cat in the middle is still up in the air.
louder in a good way or bad :stirthepoI had one on my 00 rango 5.9. It didnt really effect anything when i took it off just a HELL of a lot louder.
depends. look in my sig, dont do it. OBNOXIOUSLY LOUDlouder in a good way or bad :stirthepo
so with a 5.2 it would probably be even louder right loldepends. look in my sig, dont do it. OBNOXIOUSLY LOUD
yeah, i mean i have set off two car alarms already just starting my truck, don't do it. i really did think it was cool at first, now it pisses me off.so with a 5.2 it would probably be even louder right lol
