IMO glass packs are awful, hate the sound of em. i love the sound of magnaflow muffler not too loud but has a great tone, i have one 3 inch in/out straight thru muffler(turbo style) on my 3.8 turbo setup with 3inch exhaust and love it. also have a magnaflow on my tahoe.

i wouldnt run a glass pack, but its not my car and i dont have to listen to it.

actually glass pack does not sound that bad. I had the stock mufflers cut off and replaced with tips. I then had the resonator replaced with a 12" in length glass pack and it sounds decent. It is kind of loud, but I think if I add another glass pack along the lines or a round Magnaflow then it would sound pretty sweet.

i was thinking the just the glasspack or turbo mufler would not have enough back pressure,because i don't have any cats or resonators,i though it would be better than just a glasspack of muffler

the only think the back pressure is really going to do is take away from your high end torque (IIRC) and itll help your gas mileage.. and no before anyone says it im not stupid.. running open cats i was getting 17-18mpg HIGHWAY.. i bolted up the ass end of my exhaust and gained 7-10MPG i get 23-25mpg on the highway now..

as for the glass packs.. its part of being young.. im already way over glass packs as i had dual GP's on my 93 F150 5.0... ***** was loud but the drone was unbelievable on my way to work (1 1/2 hours one way.. all highway..) so i hacked them off and rad a Di/Do magnaflow.. nice mellow tone when you pussyfoot the throttle but when you lean into it that **** gets loud.. people know your coming then.. hehe got pulled over many 'a' time' with that truck simply for the noise (couldnt keep my foot out of it..).. good thing my grandfather is a cop.. hehe

Back pressure doesn't help an engine make power under ANY circumstances, period. It hurts performance at all times. If you bolted up your exhaust and gained mileage, it's not because your car now has back pressure and performs better. It is because the exhaust gas is undergoing the scavenging effect, which helps make power and increases efficiency. Tuned long-tube headers work off of this principle. Engines don't gain 15-20 hp from these headers because all of a sudden there is more volume for the exhaust gases to flow. It is because they are tuned to produce the maximum scavenging effect possible. The only reason backpressure is wanted or needed is to utilize the EGR system on these cars because the system is set up to operate based upon readings of the pressure in the exhaust.

thanks for clearing that up chris and either way he wont really gain that much power with just an exhaust, if he did it properly and flashed the CPU to run without the egr it would work better at making a little more power correct?

You're right, exhaust is not an area to gain a lot of power with a stock to mild engine. If he did the exhaust work correctly, he could gain a noticeable amount, and the CPU wouldn't need to be adjusted for it to work right. Even with a great exhaust setup, there should be enough backpressure for the EGR to work properly, and turning off EGR nets a 0 hp increase in power.

On my 96 vic, I have no cats and long glass packs and no tailpipes.

I think it sounds great when driving around, but when on the interstate or highways it drones something aweful. It's not extremely loud, thank god, but is most annoying. I just turn up the radio
