Weird. Buying exhaust parts from a book place.

No way. Amazon rocks for EVERYTHING now. I use them ALL the time. Customer service is awesome, prices are always great, shipping is almost always free. (I get 2nd day free for just about everything with my Prime membership).

Amazon has been more than books for a LOOOONG time now. They are getting to be a HUGE company and by far the biggest online retailer.

I know - just pulling your leg. Got a couple "unmentionables" for my wife from them a couple of months ago.

Marketing genius.

Codes all dead now...
