That’s true, they do sound pretty bad on some cars. Mine are Thrush glasspacks. 2 1/4" pipe and 24" long. I was going to put Flow-Tech Raptors on instead of glasspaks, but I’m cheap and I love loud exhaust

YUCK… My advice: don’t put any type of loud exhaust on a V-6 PERIOD!! They sound like crap no matter what you do to them. A buddy of mine just had duals put on his V-10 Dodge. Man… talk about wierd sounding. Sounds like an airplane taking off.

Diesels kinda sound cool though… Specially when the turbo charger kicks in on a ford powerstroke (a ford my dad had a long time ago) it sounds like a jet engine roaring and whistling sounds really powerful…

Yeah, that’s a cool sound. I used to have an ‘83 Chevy 3/4 ton 4×4 with a 6.2 liter diesel (non turbo). It had straightpipes with glasspacks on it. That thing honestly sounded good. Sort of like a really low pitched rumble. Tony Kimmell Normal, IL 1980 Chevy K-10 "Black Beauty" 1976 Ford F-150 "Big Nasty" 1989 GMC S-15 "The Bruise" 1978 Chevy Impala "Old Grey"

That is SO true to not put loud mufflers on V6’s. A guy at my school has an 87 Firebird 2.8 with a Flowmaster crossflow muffler that is really made for the V8 models. This thing sounds like it’s going to fall apart at anytime. I have never heard a diesel with loud mufflers but judging from what Tony said they must sound neat. What about straight Sixes? (300, 292, 4.0 Jeep, etc) Do they sound that good or just like a loud UPS truck? – Hide quoted text — Show quoted text ->Diesels kinda sound cool though… >Specially when the turbo charger kicks in on a ford powerstroke (a ford my >dad >had a long time ago) >it sounds like a jet engine roaring and whistling sounds really powerful… > Yeah, that’s a cool sound. > I used to have an ‘83 Chevy 3/4 ton 4×4 with a 6.2 liter diesel (non turbo). > It had straightpipes with glasspacks on it.

I dunno… I have true duals without cats on my ‘86 Chevy Silverado w/350. Has 24" thrush glasspacks and 3" stainless steel tips. Sounds great to me! MY 2 cents… Tony Kimmell Normal, IL 1980 Chevy K-10 "Black Beauty" 1976 Ford F-150 "Big Nasty" 1989 GMC S-15 "The Bruise" 1978 Chevy Impala "Old Grey"

The point I was really trying to make was that glasspacks are generally quite loud compared to Gibson or other systems and sometimes pop or get distorted sounding at high rpms I must admit I am not a fan of glasspacks as a whole but I have heard some really nice sounding Mustangs with glasspacks and some really bad sounding cars and trucks with them. I guess pipe size has a lot to do with the sound quality. I’m glad to see you have achieved good results with yours.

Have a look at Gibson systems. They specialize in making high value systems that offer significant power gains but still maintaining near OEM sound levels inside the vehicle. If you want a reasonably quiet interior and a nice sounding exhaust DON’T buy glasspacks. My 2 cents jason

Response:
If you think you will increase power with a glasspack, hold it up to the light and look at all the louvers hanging out in the exhaust flow.That way, when you are down on power you’ll know why. Also, be aware that if your exhaust exits under your vehicle, you risk fumes entering your passenger compartment and the steel parts on the underside of your vehicle will develop an oxidation problem.
