Who is running dynomax mufflers with headers? Do you have any sound bytes? Here's my setup...going on in a couple weeks. TA full length headers, X pipe, 2 1/2" pipes, dynomax mufflers with tailpipes tucked up under the bumper. Sound like fun? I hope the x pipe fits under my car.
I don't have headers, but here is my clip. http://www.mikeatwood.com/MikesGS.wma right click and "save as"
The super turbo's on dad's car sounds awesome. It's a 67 Chevelle with a stout big block. He's running 2 inch headers through mandrel bent duals. These mufflers have a very nice tone at idle and are not too loud at WOT.
Adam are you doing the install yourself If you are let me know I can give you some pointers. Just finished Todds not to long ago. Here are some pics. http://www.v8buick.com/showthread.php?s=&threadid=17180&highlight=X+pipe
