What do you all thinnk of running straight pipe? It's for a 89 22re and it is for off road only so noise isn't an issue. I know that i have to keep my o2 sensors and was just wandering that if straigh tpipe is alright for the motor?
A straight pipe will not be good for your motor, it eliminates all of your back pressure, which you want to have less of but no muffler and no cat will hurt your motor and it will also be slower. But what you can do is take off the cat and put on a high flow muffler like a flowmaster or something and then put a turn down right after the muffler. This will give you enough back pressure without being restricted and it will sound better too, and still probably be loud if that is what you like, and it won't hurt your motor. But to do this you will have to register your truck as an off-road vehicle which means it is strictly a trailer queen, no street driving at all. If you notice they still run mufflers on TT's, the pipe before is pretty short and a turn down after the muffler, that is probably your best bet.
DIRT'S FOR RACING, PRERUNNERS ARE FOR GETTING THERE!
If you mean a straight pipe instead of a cat, it should be fine, but i wouldn't run it without a muffler. I once ran my toyota with just headers while I was going to the muffler shop and man was it loud! I was setting off car alarms left and right and started going deaf. Well anyways, I didn't notice any performance issues, but it sounded like crap. I mean it was loud and all, put you hear all the sputtering and misfiring.
