Dyno Don Headers and GMMG/MadHammer Exhaust

I'm clearing out room in the garage after my LS swap and I've got:

A set of Dyno Don's headers with the single 3" Y-pipe. 1 3/4" primaries, no AIR.
Bought them in 2012 and didn't get the car on the road til 2021. They have roughly 1,000 miles on them. They're still in very good shape with no dings or dents. Ceramic coated, but some very light surface rusting is popping through in some spots.
$600

GMMG/MadHammer chambered catback. Bought in 2013, same as the headers has about 1,000 miles on it. Comes with the quad tips. Very good condition, does have some red overspray on both outsides of the tailpipes from when the car was painted, but can be scuffed off.
$600

If you're interested in both, $1000.

The combination does have a good sound to it. To hear a clip of it at 25:05:

Local pickup only in Sterling Heights, MI 48312.

Wish I was closer. For whomever is interested, that GMMG exhaust is absolutely the BEST sounding exhaust for third gens IMO. GLWS.

Good price for a cool setup! I'm several hours away, but if you still have this in a couple weeks, and if i can sell my new headers for close to what i paid I'll make the road trip! I'll be in touch!
