Just A Question To Throw Out.....
If I hacksaw my stock muffler off and put a straight pipe in replace of it, would it be a deeper noticable difference? and is it a good or bad idea?

(i've been wanting that clean straight pipe look like mustangs have)

It'll definitely be a lot louder.

 

[baby sho]

it would sound like crap, and you would annoy the crap out of everyone.

Get a decent free flow muffler....

I have to disagree. I have done that exact thing to my 97 GL, and I like the sound. I have left the rest of the exhaust system intact, just removed the muffler and straight-piped it. It can sound a bit raspy at high (e.g. 4k+) RPM's, but it's not bad. And it's CHEAP.

Actually, no muffler sounds good on a vulcan. I've got an exhaust cut out right before the muffler and it has a nice low tone to it. Sounds almost like a muscle car at idle, and isn't too bad the rest of the time. I've had a lot of comments about it, even by the guy who did the welding for me. He was impressed. (the guy does work on mustangs btw)

Twilight (Alex) had his Duratec straightpiped and it sounded like

You don't want to do that. VERY raspy and funny sounding.

I would just recommend going to a local exhaust shop if you want a muffler that's not from the Internet. However, if you want a freer flowing one you will pay a lot more if you don't get it from the Internet. I am partial to flowmasters if you know of a place you can get one. I have a 40 series deltaflow.

My friend has a 40 series flowmaster on his Nissan Altima and it sounds very trebbly and raspy. i dun want that rice rocket sound on my taurus. should i go for the 50 series (i think its for SUVs but it should give a deeper throughtier sound)?

The 40 series *should* be the one that is deeper and a little louder. The 50 series is more refined with a slightly less "agressive" tone but with the same performance as a 40 series. The 50 series will be quieter inside the car. However, the 40 series (Delta Flow) isn't really all that bad as far as interior noise. It sounds like the 40 series might be more of what you're looking for if you just want a REALLY deep throaty sound - it will provide the most agressive tone The key to preventing the raspy sound is to leave your resonator intact. If you remove the resonator it WILL get very raspy. Hope this helps.

Not sure how much it helps, but here is a clip of my vulcan with the 40 series Deltaflow:

btw... what engine does your friend's Altima have? And does he have a resonator?

he has the 3.5 liter engine and im not sure about the resonator.

OK, just wondered. It seems like any 24V engine has a bad tendency of souding raspy w/o a resonator.

My buddy has a old 72 Cadi Coupe DeVille and he put a glass pack on his exaust, would that hurt the engine at all, i've got a 3.0 V6

I have a Duratec, and I have a 40 series on there now. I had been running it without a resonator. CACA. It sounds very raspy. I have an aluminized glasspack for the resonator now and it sounds great. It has a nice, deep sound to it, and sounds great when I let off the gas when rev-ing the engine. I can hear the valves calming down

I got my 40 series for about $45 including s&h from an ebay company. Any other flows are $55 plus from other companies.

Question for guys that know alot about engines: I know that some engines rely on backpressure to keep the car going, especially 4 cylinders. I can see a huge flow allowance w/o a muffler, but does the duratec have enough output to run fine w/o one and not sacrifice performance?

I bet that sounds (and rides for that matter) real nice.

As for your question.....the answer is no.

I've never heard of a engine needing backpressure. I think it'll run fine with straight pipes as long as you keep the pipe diameter a little on the small side.

I don't think the number of valves affect exhaust note. It's a matter of cylinders (number and size) and possibly the cam(s).

Maybe Bob or somebody could amplify, but as a non-car example, Honda motorcycles were manufactured with to differnet cams. One was refered to a 360degree cam, and the other a 180 degree cam. One had a great exhaust note, the other-- not so much.

The volume of the cylinder also makes a difference. More CCs/CuIns pre cylinder, the bigger the boom.

After hearing lots of Hi-Po V-8s, I seriously doubt it will be possible to make a V-6 sound that good. But that's relative, and some people may like the sound of straight pipes or glass packs.

I think over all something like Walker Turbos would be fine. Walker brand is carried by a lot of muffler shops.

I don't know about that. I think you can come darn near close if you keep it "subtle" and don't make it too loud. I had a friend with a 4.3 S-10 and it sounded better than a 350 IMO. Course I don't like the sound of GM v-8s anyway...but that's beside the point.

Backpressure is inefficient for engines. You just can't go too big on your exhaust pipe, because the exit velocity of the gases will be too slow, and the gasses will cool in the pipe. This will cause rusting out, and will actually create backpressure.
