    Default Exhaust for an 88 Silverado with a 350

    I'm constantly debating on what I want to do with my exhaust. I have an air intake but I only have a stock muffler. So far all I can find in my price range that is 3 inches is a Summit glasspack which is around $20. I want a nice crackle and roar but not so loud that it will be very noticeable at idle (for riding through town). Any suggestions or comments would be helpful. Thanks.

    I added a glasspack on my 89 Suburban with the 350. It had the stock manifolds and cat and was not loud at all. I thought it sounded pretty good, and I'm not a real fan of the glasspacks.

    I have flowmasters on my truck and they're nice and loud when you step on it.., but for cruising it's nice and quiet. Is it a standard? cause if it is it might be different depending on when you shift

    The truck is automatic. I bought the Summit glasspack and it should be coming in soon. Thanks for the comments everyone.
