See that other thread for the end result of my Gardner purchasehttp://www.camaros.net/forums/showthread.php?t=168582
I just sent back the muffler Eric said was better.
Still not the way I would for my car and certainly not for that price.
I would ask for pictures - and even have him send the muffler first,
so you don't have to eat the freight on the whole system if you are not happy.
ended up costing me $160 in freight both ways.
BUT MOST IMPORTUNATELY - Why would you spend $1000 when you can get a system just as nice for $399?
with an extra 1/2 hour in labor - there is no difference in the Gardner system.
In fact until he finds a better supplier for the muffler - Gardner is of less quality - IMO
but hey - it's only money?
