WTT or SALE my new SLP dual dual muffler for your LS1 catalytic convertors

Trade me your LS1 catalytic converters & I'll send you my new, never mounted, SLP dual dual muffler .

Or, you can buy the muffler without trade , from me for $125 + shipping.

You can't buy dual dual mufflers new anymore from SLP, & when you could, SLP sold them for $290.

Or if you just want to sell your cats, I'll buy them for $100 shipped.

I have LS1 catalytic converters for a 98. They are not off of the car yet. When do you need them?

Are you trading everything you have pictured in your post. I have the stock manifolds and cats still attached sitting in my garage. I'm in the Harrisburg area if your interested in meeting halfway between on the turnpike I'll trade you. I'll post a pic as soon as I'm done figuring out an update I just started.
