HEY guys i was wondering what a glass pack would sound like on a trep. i am thinking about getting one because they sound cool and are pretty cheap. i jsut dont know how to install it or where it would go so i was wondering if you know how to. Also what brand and how much money do you expect it will cost in the end :confused:

i have a "Thrush" glasspack on my other car, (temporarily), it ran me about 25 bucks. sounds alright, and it was much cheaper than getting an OE exhaust for now(im currently restoring a '56 mercedes 190 sl...but on hold till next summer). go online and get the summit racing catalog...theyll have it.
in my trep, though, i ripped out the entire exhaust back of the 3rd cat, and replaced with bent pipe to a flowmaster 40 series muffler that sounds awesome. for the fiberpack, though, i would imagine that you'd probably have to do the same procedure, since the stock resonator at the rear is a turbo style muffler (on the 3.5l, the 3.3 just has that big box under the rear seats...3.5 has both the box-shaped muffler and the resonator out the rear...the muffler lookin thing with dual pipes).
how i installed it on my mercedes, though, was a little different. i put it on real messy, right after the header, no pipe out of the rear. i just put it on to keep it quiet. (its a 4-banger...1.9 liters of raw, carburated, german horsepower!!!)
the best way for you (if you want to do it right) would probably be to take the car, glasspack in hand, to a muffler shop. this is where it could become pricey...unless you know somebody with a hydrolic pipe bender...
tell them to put er' on the lift, cut off everything from the cat back, fab a replacement pipe, and bolt the glasspack on (dont weld, cause you may need to replace the fiberglass inside later on)...hope this helps...oh yeah, people are gonna tell you that you'll lose low end torque, that is correct, but not so much that it'll be a problem (there's still back pressure from the 3 catalytic converters)...hope my babbling helps

glasspack is just what it sounds like: a tubular muffler, with a perferated pipe inside, surrounded by yard upon yard of rolled up fiberglass. gives off a deep tone and 0 backpressure. Thrush is a manufacturer, cherry bomb is another type...theyre real cheap...0 backpressure disposible muffler

ok a glass pack is a muffler like straight pipe with fiber glass or something on the inside. It is basically to pipes one inside another and in between that is fiber. This makes the exhaust sound really powerful for about 20 bucks. (voooom, bim, bim bim ya know?) anyways please help
:(

No no, not ricer sound at all. You've certainly heard Harley-Davidson motorcycles havn't you? They make them sound more like those.
