That's the one! It's nice to know that people keep things that are posted here!
I cut that together a while ago from a magazine image I had.

Hope it helps.

can someone label what each canister is from left to right? iknow the first 2 are muffs and last 2 are cats. thanks in advance.

Left to Right:

Mufflers, Mid mufflers(resonators), center catalytic conveter, y pipe, and catalytic converter on each side of down pipe.

in a nutshell,,,, 4 mufflers,, 3 cats.

Most of the members heve delete the 2 center mufflers in opt for a straight flow exhaust to rear mufflers.

interesting...thanks tony. i asked a friend of mine why my exhaust was so raspy and he said theres a hole somewhere and its coming out near the driver/passenger front doors. if i delete the resonators and put magnaflow mufflers u think i can pass emissions?

Negative. In that picture, the center "item" is a resonator, not a catalytic converter.

sonyman

If it's near the doors the most likely scenario is that one or more of the gaskets connecting the catalytic converters to the exhaust manifolds or piping has failed and is letting exhaust gasses flow through a small gap. If this is the case it's a cheap fix. The resonators and mufflers are farther back and will have no effect on this.

thanks for the quick response sony but you think removing the resonators will affect emissions?

sonyman

It shouldn't.
