Default Upgraded Exhuast?

my rig is due for a new catalytic converter and O2 sensor. my idea was to buy a high flow cat (flow-master ) a cherry bomb glass pack and tailpipe. i need to know tube diameters for inlets and outlets so i know what im buying first hand. or if cherry bomb is not in your guys favor i would appreciate what suitable muffler would give me a good rich tone. thanks guys

Check the exhaust thread. Everything you need to know is in there.

The pipes are 2.25 diameter, can't remember if its in or out. I have a high flow cat with cherry bomb with a turn down infront of the rear axle. I love the sound!!

Here ya go.. This link has the diagrams for the parts used to replace OE exhaust. You can use the diagram / parts to see what size your exhaust is based on the year.

On a 98 it shows it's 2.5" into the cat and 2.25" out of the cat.
