I agree. $800 for a muffler? What's that good for - about 2HP? A couple of years back I bought ceramic headers for my Vette, had them put on along with a complete dual 2.5" system fabricated and a couple of nice meaty Dynomax mufflers put on the back and still got change from $800!
I think the mufflers were $48 each
And they sound awesome! Pics in 'my garage'.
