so i have a 92 DA and i was getting exhaust work done today, we all know how the exhaust is set up, it comes straight down the right side then that damn 90 degree bend to the left side, well i got mine done on the right side, other than not looking natural due to the bumber cut for the exhaust, is this a good idea for better flow? sacrafice small looks for better flow? good idea or bad?

There are several factors to consider. Most engines work best when there is some kind of back pressure preasent inside the exhaust system. If the proper amount of back pressure isn't there, it could hinder the performance.

Another thing is exhaust pulses. I don't personally have equipment to test such things, but I do know that if you mess up the pulse of the exhaust in a negative way...well, your car will be hindered.

Who knows? Dyno it vs. your oem and let everyone know

 

It wont make much difference.

 

The one hp you gain isn't worth looking like a tool with the tip coming out the wrong side of the bumper, ...or is it?

Um, I always thought it was exhaust flow speed that improved engine performance, and that having an overly large exhaust allows it to slow down too much reducing performance. I really don't see how any backpressure can ever be good for any engine, performance wise.

I've even heard the argument that backpressure is good for low rpm torque. If that were true, wouldn't aftermarket performance exhausts for trucks preserve the factory backpressure? They don't though, they're as free flowing as aftermarket performance sports car exhausts.

Not trying to start an argument. Hopefully someone will post some real world data concerning this.

 

Backpressure is a major issue that should not be overlooked..But the looks count also ..

 

i got a 92 also, i got it running down the middle till the gas tank, then it takes that hard 90 degree turn to the right, but then i have it come stright out instead of doing that other stupid turn the way the old muffler was. There basically isn't a great way to stop that turn. Unless you make it turn up at the beginnning of the pipes.

"Back Pressure" in exhaust? Hrm, wouldn't it be better to have LESS back pressure. Kinda like breathe in air and farting to let it go, anything in the way makes it harder to get out, bad example but not exact on how back pressure can help. Sorry to get off topic.

But, it's up to you if you want to switch it to match the body kit or whatever it is; better to have one then to not have one at all. :D

 

you do not want backpressure. you want to keep the exhaust velocity high.

a very good read

 

wow. the whole all motor forum is wrong then. : s

it's all arguable. in generable its a good idea to have a little bit of back pressure to push the exhaust gases through the piping and out. little bit is a relative term.
