I've got a used flowmaster 40 series for sale off my 98 ram.

It features 3" i/o and is off-set. It was installed and I ran with it for about 8 months before I got tired of the highway drone. Too loud for my wife.. I switch to the 50 series. I can send pictures if you'd like.
I'm asking $50.00 plus shipping.
PM me or send an email to bassplayinsweets@yahoo.com for pictures

Thanks for looking!
