Hey CL, I'm selling my ISF ISS Forged DES exhaust. This no-longer-produced exhaust uses Magnaflow mufflers with true thru-bumper dual tips, replacing the factory oval tips. Side branch resonators have been added to this exhaust to reduce drone. See details in this thread on these side-branch resonators:

I'm asking $1,200 and local sale please - not interested in shipping. I'm in the Phoenix, AZ area.

You still have till this weekend to drive a pickup down to Barrett Jackson and drive home with a sweet exhaust...

Lol. Let me know if you'd consider to ship. Thanks

Did it cut down on the drone?

Yes, significantly. Check out the link in my original post for a longer explanation on the side branch resonators. Then after adding the side branch resonators, I added silencers in the lower exhaust tips (very easily reversible). See post #50 in this thread for my post related to that mod:

Those 2 modifications together reduced the drone very significantly. It also quieted the exhaust down in general a bit, which was just fine with me.
