Dual Exhaust?
I was driving around with my friend one day, and he suggested i get dual exhaust on my olds eighty eight LS, now this seems like a good idea, but i was wondering about how much it would cost, and how it would sound and stuff.
i'm thinkin of going with 2 catbacks, but my friend thinks straghtpipes are the way to go, i dont want too much interior noise, but i want my car soundin good, so i dont know.
i plan on gettin this done in the future though, considering i'm broke as a joke right now.

Straight pipes will be loud. I have 3" straight back to a magnaflow muffler. I have one of the loudest exhausts you will ever hear on a Bonneville. If you want to keep the sound under control go with a high flow cat, resenator, and a high flow muffler. I'd use 2.75" pipe unless you plan on heavy modding.
And as far as dual pipes, I wouldn't suggest true duals, but rather a split coming out of the muffler. True duals may take away a lot of your low end torque.

yea, I lost a little low end with my 3" single pipe, duals would loose even more.
And for cost, if you use existing piping in your system, you could do it for just a couple hundred. If you do a full cat back system, my guess would be anywhere from $500-$900 installed.

i think i'll stick with the pipes already in my system, and have em do dual tips.....
so, will there be any real power gain from the new exhaust?

this mod alnoe, probably not really. You would need to combine this with other mods like a CAI, 180 t-stat, maybe a chip, to get any real use out of it. Exhaust mods generally allow other mods to perform better and offer little noticable power on their own.

at least that'* what one guy my dad talked to at his job (car dealership) said.

CAI is a Cold Air Intake. This would be like the pipe and cone filter intake vs a stock airbox.
and the 180 will help your car run closer to 180 degrees vs 195 degrees like the factory one is set at. If you are sitting in traffic on a hot day, you'll still see the high engine temps. but if you are cruising down the road on a fair day, you'll see about 15^ colder engine temps.
