replacing cat with str8 pipe.
Ok my buddy has a 98 integra and he says he heard everywhere that if he replaces his stock cat with str8 pipe on his stock car with stock exhaust he will gain 20hp, i pulled a bs card on him but ey i dont know everything, just to prove my point can somebody give me a opinion on that?

you might gain some hp, it would help alot only if, the stock cat is old and super restrictive. But straight pipe is louder.... too loud depending on muffler to go with it, but 20hp.... maybe if you consider one thing, the car is 140 stock, over years of use, and wear and tear, and a dirty clogged cat, you might be at 130, or less, with straight pipe and tune up, you might be back at a 145-150.
Im gonna stop, im just talking out my ass now.

Barely any... you guys toss around these 130 and 140 numbers like its actually getting to the floor, which most likely it isnt.
say 4 hp at the most.. which he wont notice, only a smooth power band. He'll also notice a drop in low end power, and might gain a bit in the top end.. other than that he's just making his car louder, and the exhaust out the muffler dirtier..
If he still wants to do this, he's going to have a CEL, but that can go away with a non-fouler to trick the ECM into reading something decent from the O2 sensor..
or he could just not do it at all..
