what are some of the things yall have done with your exhuast including sizes

i am runnin just a cat at the moment but its bad and clogged so not loud at all creatin alot of back pressure im just gonna chop it and run straight back to a cherry bomb glasspack then ditch it with a 3" tip right before the passenger wheel until i get a better job then im gonna run dual glasspacks out the rear probley 2 1/2 pipe and same 3" tips

Both my broncos have higher quality glasspacks. They are actually pretty quiet, even with V8's. The main problem is they are frowned upon in the offroad world because backfires can pass straight through and cause forest fires. I believe they may actually be illegal in some places.

If you read up on non-biased tests, exhaust mods do very little for overall performance. Infact if you're not careful, you can easily reduce power. The backpressure helps your low end torque. So unless you are turning 7,000 RPM, I'd recommend spending money on other things.

so straight back to glasspack would be a bad idea since i tend to to some off roading and spend quite a while in 4x4 low

I'd recommend a regular old muffler, but you gotta run what you can afford.
