thinking about doing a custom exhaust on my SE
what would be a good size piping to go w/ if i stay w/ a single outlet
wanna keep the sleeper look and love not being able to see any tips or anything
i know 3" would only sound cool and would kill my torque
and would only pay off if i had boost
so 2.5" or 2.75" ?
oh and what recommendations do ppl have for ypipe?

I do have dual exhuast , the pipework is 2.5 inches. It gave me a real kick. I'm not technically inclined in the Exhuast dept but I do know some back pressure is good, and that your engine can only send out what it takes in. I'd say 2.5 just because that's all I ever hear about on these forums..but hey, all you custom single exhaust guys should start speaking up you true sleepers!

i have a 98 s.e v6 mtx and im keeping with th e sleeper look also. i went with a full 2.5 inch exhaust from the cat with a dynomax superturbo muffler. just to keep the sound low while at cruising speeds. i have pics on my car domain link below, along with other mod pics. i also plan to get a resonator for a smoother sound. plus i get a little rasp when the muffler is cold. my next mod is svt brakes. i have a optmized y for now later i might go with a bat with hi flow cat and gutted pre cats.

2.5" piping would be the best choice if you wanted to stay with single.
Bigger would not be better and definitely NOT sound better on a low displacement engine.
BTW - Back pressure itself is NEVER good. 'nuff said!

I don't claim to be very smart when it comes to....well cars, but I always though a certain amount of back pressure was good for N/A low displacement engines? Sorry to hijack this thread.
BTW I have a catback system, 2.5" all the way back and a remus muffler at the end. Has a tip, but I run so rich right now it never shines. No one ever expects the car to sound the way it does.

Why would you want expelled gases trying to push their way back into the combustion chamber? Not my cup of tea, but it's your car....

I hope it sounded more confusin than that!

Oh I don't have much back pressure. But I had it explained that some of those gases are unburnt, there for stay for another cycle to get burned again. That would be why people would loose milage, at least thats how I understand it.

How would unburnt fuel vapor get burned up in the exhaust system?
Even if said occurance happened how would it effect the gas mileage of the "engine"?
How would unburnt fuel stay in the cylinder to be burned again?
Needing back pressure is a myth. It is all about exhaust velocity and scavenging.
The best performing setup would have maximum velocity, no back pressure, and optimum scavenging.
Using oversized piping for a specific engine size kills exhaust velocity and therefore overall power.

I always thought that a rifle had better aim than a pistol for the sole reason that it had a Barrel for accuracy. My analogy is that Some, in fact only a little, backpressure would be good in that it gives the exhuast a compressed direction and flow. If that is wrong then I take it the engine is what should be the only thing compressing the flow of exhaust? Just trying to get my facts straight..
