Anybody added these glass packs or some kind of high performance exhaust system. I am going to have my Tahoe looked at today. They say Glasspacks, free flowing, help a little with gas mileage...plus, IT JUST SOUNDS MEAN AS HELL ON MY 4x4!!

I used to have a 1962 GMC 3/4 ton pickup with a 350 4-bolt that I took out of an old police car. Put some glass packs on that beast and it woke up the neighbors.

 

[bocajapache]

so glass packs to loud? or screw the neighbors? My Truck sounds good!!

 

[ChevyFan]

I lived in an apartment complex at the time and when I started up my truck each morning at least one car alarm would go off. I would be upset now if some young punk did that to me, but it's all good. I really didn't try to wake people up at 6:30 AM.

 

[bocajapache]

Talked to the shop who is going to be doing my work for me on the exhaust system. He is telling me with the CATS in the TRUCK and the glass packs/free flowing system. it will sound good. He advised if I did flow masters, then it would sound pretty much like the stock exhaust. I will let you all know how they sound when I get them on. Hopefully this week.

 

[ChevyFan]

yeah, looking forward to it.

i had true duals put on my 97 'hoe, with a vortex turbo muffler and it is a lil' bit louder but not bad, and it helped me pull 23mpg on the way back from north dakota last summer

 

[bocajapache]

that's 1 reason I am doing it..but also I am getting the Tahoe programed for me on a DYNO!!!! which will freaking help gas like crazy. I will ahve to run high octane though 92 super unleaded and get a new thermostat that runs cooler, which is like 40.00

 

[ChevyFan]

I wasn't aware that you could get that type of MPG enhancement. What are the drawbacks?

 

[bocajapache]

Steve, I just had it programed satruday. She is running like a mean bitch!! hahaha. I am monitoring MPG this week and let you know what comes out of it. I HAVE MORE POWER, I don't know the terminology, but my truck can get on it if I need it too. Runs smooth, timing is perfect on it now. I can get the chart comparisons maybe if anybody really wants to see them.

Exhaust

I have a 95 two door Tahoe. I gutted the old exhaust did it true dual from the headers to tips. I used cheap mufflers and now I am getting some leaks from the muffler. I was going to do away with mufflers all together and do GLASS PACKS. I know it will be louder, but has anyone done it yet to confirm what if it is a good loud or a junky loud. Let me know.

 

[ChevyFan]

Josh, what engine are you running in that 95? I've run glass packs with a 283, 327 and a 350 4-bolt police special. The sound is really a byproduct of a lot of different variables like your headers, catalytic converter, and the quality of your glasspacks. I mean, I've known people who have tried to get louder, and others just want faster exhaust output and don't care about sound.

What are you looking to acheive? Performace or a good deep sound?

 

[ChevyFan]

What part of Idaho are you from, btw? I was born in Boise and lived 15 years between there and Spokane, WA. Went to school for a bit in Moscow, spent a lot of time up north too near Sandpoint. Good to have another spud on the site.

 

[IdahoJosh]

I have a stock 350 in my 95. Aftermarket headers, I am not sure what brand, they were on it when I bought it. I am looking for better performance which I have already achieved by doing away with the cat, but the mufflers I bought were cheap and like I said they are falling apart and you can hear them leaking. I am looking for a deep strong sound out of glass packs but I have been told it will sound great and horrible. I personally think it will sound great. BTW I am from Coeur d'Alene born and raised. Good to see someone knows were Idaho is out there!

 

[bocajapache]

I am getting mine done still. I just had a new daughter and money is a little tight for me. But I promise I will get mine ASAP..maybe next month. I talked to the mechanic about it again. He is a really good friend and would not steer me wrong. He said with the CATS and glass pipes, true dual, it will sound great. If I were to put flows which I almost did, they would be pretty much sound stock and not help much with gas mile. In Texas, I know we have to keep our CATS on, I think, in order to pass inspection, so I will have to leave mine on.

:?:
oh, what kind of gas miles any of you getting IN TOWN? I have the v8 vortec on a 99 tahoe.

 

[IdahoJosh]

I got my glass packs on and it sounds great! In Idaho we dont have emissions inspections so I did two inch pipe from the headers to glass packs and two and a half from cherry bombs back. It sounds pretty tuff. I had mufflers on it and yeah it sounds pretty much stock. But now, people are paying attention! You know what they say in Idaho loud pipes save lives!

 

[bocajapache]

Awsome Josh!!!! I think I will have my packs installed tihs weekend. Question now.....DO I INSTALL 4" TIPS OR 3" TIPS. Anybody have a suggestion on this? I want it to sound good but not annoying loud.

Thanks!!!
Jacob

 

[IdahoJosh]

The tips I put on are 4inch, but they have the honey comb looking inside much like the inside of glasspacks. I think it gives it a deeper tone instead of being so pipy, does that make any sense? They were like $40/piece at the parts store. Hope yours sounds as good as mine!

 

[bocajapache]

THE GLASS PACKS ROOOOOCK!!!! I HAD 2 MAGNAFLOW PACKS INSTALLED WITH 4" CHROME TIPS!! My friend says it sounds better than his complete magnaflow system/muffler. Anyway...when we are able to post pics on here...i'll take some and post it! I love my sound and I love my pipes!!! Not to loud and sounds great! I seriously recomend them to any of you all if you want that mean sound.
