i just got 2 thrush glasspacks for my v6 stang. im taking that stock thing off putting a ful dual cat on it with glasspacks. thing is do i do side pipes, or just go out the back?
i put the glasspacks on. sounds deep and loaded when you jump on it. i say a must for all cars. go to the pack. side pipes dont do the same asss back i fixed that mistake
glasspacks are good on certain motors. Not good for all, soundwise. all the old chevy trucks have'em and good god it sounds like someones just shooting an automatic shotgun, nasty as crap. Of course these are like the 20 dollar glasspacks, but well, ya know. But I am getting a set of "glasspacks", but they are triple chambered and vortexed, Borla XR-1 Racing Bullets, super nice clear sound.
I figured people would have stoped using glass packs years ago. They got all that glass in them that slows air flow down bad and makes the car sound like a old Chevy truck. I hope they have improved the design of them over the last decade.
Well, most original style glasspacks are still as crappy as they were years ago, but the Borlas that I'm talking about are heat treated and compressed to form a solid wall (so there is basically no reduction in sound level).
