88 silverado exhaust problem
 

Hi everyone,

I recently got a hold of and 88 silverado 4x4 truck. It has a 350 in it and has true dual flowmaster super 10s with 2 1/4 inch pipe and no cats, but for some reason it is still very quiet. I had a 92 that didn't have this issue. Can anyone give me some insight?

Thanks in advance.

Can you get under there and take some good photos of your exhaust so we can see what you have? Dual super 10's and no cat should be obnoxiously loud.

It would have to be later on. However it is just a basic true dual system. Side by side mufflers. I've even checked to see if they are backwards. Still can't figure this out
