I dont have a clue...John would be the person to talk to.. I am a customer just like you might want to be... The easiest thing to do is call him for a slot, have e him look at it and quote a price..... This site is, or was designed to be critiqued by people that have used the service... How much John might charge for any given service is out of the realm of a simple customer....
$40 for muffler swap is the normal plus pipe
