Whats the stock exhaust pipe size on a '78. Reason being is that im installing glasspacks this week didnt know if they were 2 1/4 or 1/2 thanx

If you have another car to drive to the parts store to get your part. I would cut off a small section of exhaust pipe so you can measure it and really know what size mufflers you need. My '78 had a single 2" exhaust system.

Just curious, why glasspacks??

I like the sound alot and they seem to have good flow not to mention theyre a pretty budget friendly upgrade over stock exhaust haha

I love the sound I get from my full length Flowmaster dual exhaust system with the transverse muffler. So to each him own I guess.

I've just been burned out by the glasspack sound from the late '70 when I starting noticing car and trucks and most of the 80's where I really grow up. One of my friends and his father put glasspacks on everything they own. Cars, trucks and SUV's. They all have glasspacks.

Good luck with you system! :happy:

hahaah ya i can see how that would make you sick of the sound but thanx alot!
