I know this question has probably been asked a hundred times but I can never find the answer when I want it.
Should i keep the resonator on my 94 when I straight pipe it or should I take it off? I just wonder about back pressure and if that is a problem?
Thanks

If the exhaust is factory on your 94 you do not have a resonator but a catalytic convertor. And it would not hurt to have it fall off, unless you have to pass emission testing. Goodluck,,Rick

If your looking for a louder sound then definently take it off, my 1998.5 has a straight pipe and is louder with it out, I had the muffler off then the resonator and its noticablely louder. But if you have to pass emissions tests that might be a problem with it off.

As for sound... It sound great... Is it loud in the cab... No! As for keeping the resinator... Dump it!

Take it off....take it off ..alala. rruummmbaa.

I got one just like that too.....99's come with it that way officer. Honest injun, officer, 99's are the loudest Dodges made. They didn't know how to quite them back then.

Hey the picture looks like the thing I left off by the dumpster.

Early 94's did not have a Cat on them , so take a peek under your truck first.

This the the view under my truck:



And this is what fell out on that speed bump...



And to answer the origional question , the more backpressure you have , the worse off you are , the easier the exhaust can flow out , the better.
