i want to buy a set of rear catalytic converters, i had a custom exhaust done and now i hate the way the truck sounds. please pm if you had a set laying around.
You could do like I did. i just bought some cheap 12" glass packs from summit and used them to tone it down. There only $20 each there.

I have emissions testing in my area and passed without issue with my rear cats removed, the primary cats replaced with hiflow ones, and even in my performance tune. The tune itself probably helped me though, due to the fact my engine runs more efficient than when it was stock.
And yes, a set of small glass packets will tone you down, I promise. And the summit ones I thought were pretty decent for the price.
