Just some ss reps. No I do not. I honestly don't know where you would put it in as there is already a resonator up front and not much more room for another resonator on both pipes.

bumping this with a clip i saw of my car today of me at a carmeet revving it like a jackass...

tbh this is the first time i really heard it in person from outside my car- seeing this is making me think i may be looking into having the ar20s modded on this setup once my catless headers go in. I'll do legit clips of everything from my own cameras, but i figured here is a quick example of it now with just the exhaust.

mind u these are like 3-6k revs....

click for exhaust clip

Where did you install the AR20 and did you just do one or 2 of them?

You add the resonator into sect 1 next to the stock resonator. Been talked about ad nauseam on here for years.

My car had one when I bought it and I removed it to go back to stock.

Pros: Affordable, sounds nice above 3,500 rpm, large diameter piping possibly makes power?

Cons: Drone from 2,000-3,500 rpm, large piping requires shimming tunnel bracing (as mentioned before), mine knocked on the body somewhere when cold, it will rust, and it doesn't retain the standard exhaust "sections" that we are used to, so you can't interchange sections easily.
