Mufflers

[bubba81]

What kind of mufflers sound the best with the DOHC. With or without the cat? Anyone have any good sound clips?

[Gemmer]

if you like muscle, and have single exhaust, a single 40 series is supposedly really nice.

With the dual exhaust, get something quiet (superturbos) or if you like it louder, get a large resonator and magnaflows/40 series

But the resonator is a must on the dual

All depends on what you like. Me personally I own a V6 DOHC and want it too sound like a DOHC, so I like the sound of what most Imports use, the Straight through Mufflers with Tips mounted on them. I have straight pipe right now and it sounds great. Its raspy when first started but that goes away when warmed up.

Also please don't say you want a V8 sound. I hate it when people say they want their V6 DOHC engine to sound like a V8 pushrod!

One sound I would love to duplicate is a Ferrari sound. I heard a Fiero with a 3.4DOHC and it sounded just like the Ferrari Race cars. It even was done up like a Ferrari Repliac. Best sounding 3.4DOHC I ever heard. Too bad I never could figure out how they did it.

E-mail me, I will send you a sound-clip of my exhaust system.

Does a single exhaust give you more power, or will it take some?

Mufflers

A single exhaust has less back pressure which = More Power

[blk92z34getrag]

Single exhaust has more backpressure. But that means slightly more low-end torque, with less high-end horsepower.

But it depends on the diameter of the pipes. I can guarentee you won't out-flow 2.5" pipes, single or dual, with this engine. My exhaust guy (been in business since 85) says 2.25 all the way to a 2.25 Y would be enough. You won't lose much, if any, power with a single 2.5" exhaust. If you're worried, buy mandrel bends (You'd need at least 3) from Jegs or Summit and have the shop use them in your system.

Also, a fake dual (read Y-pipe) exhaust system does not make a big difference in performance. It's mainly for looks and can, depending on the car, enhance or degrade the sound-quality.

[bubba81]

Ok which of you is right, more back pressure = more power or less back pressure = more power.
I know more back pressure usually means more torque, and less means more horsepower. I would like both and im sure alot of other people does too.

[blk92z34getrag]

It depends on where you want the powerband. If you want more high-end power you want bigger pipes. If you want more low-end torque use smaller pipes. Generally with turbocharging or big ass displacement you just want the bigest pipes you can get.

I don't know what that guy was talking about more backpressure = more power. That's wrong. Look it up on the internet. Or ask a professional.

[bubba81]

Yeah Ill do that Thanks

i have just a twister race muffler with mandral bent 2.5" dual exhuast...very loud http://www.project04.net/montecarlo97z/ right click save as on the 10-5-04 one, and ignore the annoying voice at the end

What I meant was 1 muffler is better than 2

Duplicating a ferrari is duplicating an engine that isnt yours...which is no better nor worse than duplicating a V8...as you said "All depends on what you like"

Not trying to be an ass, but you shouldn't hate on guys (like me) who try to make what they've been stuck with into what they want

BTW, Fiero guys actually buy Ferrari mufflers...a single muffler if I recall...might be interesting to look into!

[Gemmer]

What I meant was 1 muffler is better than 2

2 mufflers flow better than 1...less backpressure (less air being forced through each muffler

single pipe is better for a quality velocity stack, but that requires no muffler

I want my car to sound like a ferarri. if anyone figures out how we can mount a ferarri muffler in there somehow let me know.
