exhaust

[pr0nst4r]

weld your exhaust pipe shut and your engine will run forever and have more power? ever driven a car with a clogged cat? your argument is silly. ugh, why do i bother posting trying to keep someone from being misinformed that backpressure is good anyway, i gotta back up common sense, its funny, anyway...

Dude, I'm pretty sure you're misreading what I'm saying.

My point is this, as referred to in my other post:

Too much backpressure is bad, yes. Too little back pressure is also bad (aka 2" pipe). You have to realize, like you said, that we're only dealing with a little B3. A 2.0L engine would probably be good around 2" pipe, but the B3 puts out a lot less exhaust. Backpressue is good, but in moderate amounts...

unless you have a turbo.

my logic is that its just a b3 we're dealing with here. benefits of exhaust pulse scavenging and velocity through use of the stock sized pipe and awesomely engineered stock cast manifold are...?

I would agree that using the stock pieces are not for benefit, but think that a properly designed system, of a smaller diameter, would do better than blasted out straight 2" pipe.

and this sure sounds like the words of someone who knows all of automotive engineering logic.

First, never said I knew all.

Second, why would I always want to speak technically? Sometimes the analogy makes it better. Do you have a problem with joking around?

Have you also noticed that each individual carb on those things are as big as my thigh? And did you also take into account that they burn nitro? This is a race car you're talking about. COMPLETELY different subject.

Your flawed logic and lack of research astounds me, hence:

wow...

Edit: Ok, this deserves a real answer...

Back pressure regulates the release of exhaust into a slower stream, that keeps the exhaust valve temperature more consistent and that lengthens their life. Based on this statement, one can conclude that not only will you produce a better condition for your engine to run in, they produce better power because of running in that improved condition.

wow...

do explain

[pr0nst4r]

wow...

What the heck is it with this "my engine needs back pressure to run right" crap?? Backpressure is not your friend, kill it. now. put on the 2"-2"5 exhaust and you will be fine.

i don't have a pic, but it is like from the cat back is like in 1 foot sections and all leak all the way to the muffler that is in stock location. i can get a pic, but won't be til tomorrow because it's raining at the moment.

Are they rusted out? Or just poorly clamped on? If the pipe is in good condition, you can just take it to a shop and ask them to weld it, but that gives me a horrible image of a bunch of straight pieces from autozone welded to each other at weird angles. Generally a shop will charge per weld on something like that and it could be cheaper, if not a better deal, to get them to just fab you a quick cat back and you provide the materials. I have a shop I go to that if I bring the pipe, they'll do whatever I want and just charge me flat rate for bends and welds. comes out nice.

if an engine needs a little back pressure to run well, how do all those drag dudes get those motors to run with no back pressure? The pipes are no longer than your arm.

From what I discerned from this thread, you should just get a test pipe made to go where your leaky, gutted cat is.




That or just get it welded up unless it's miserable. Got any pictures?

[hofficergrover]

if i can't i will use the 2 inch

[hofficergrover]

ok well i don't so i will try to fix the old

[MONSOON]

No problem Monsoon, I can fix that so he access to your info!

Monsoon says: "Even though you have me on your ignore list. I will tell you that is probably too large for a stock B3."

There that should help!

I figured if you read this thread and seen my reply youd have my back.Thanks! :thumbleft:

And yes now and then I try to be a little helpful.
