Custom 3 1/2" aluminum exhaust
Custom 3 1/2" aluminum exhaust
David at MDR Performance in Kemah, Texas fabbed up and installed a custom 3 1/2" aluminum exhaust for my car last week, and I thought I would share some pics. It came out very nice.
I wanted to bring my external dump into the exhaust, so we upped the diameter on the exhaust by 1/2", and attached it all with V-Bands. This is the second exhaust David at MDR has made for this car. The first, and the one we replaced, was a 3" stainless. He did a real nice job keeping bends to a minimum.
Yes, it is loud.

The test/merge pipe on the car for fitment:

You can see its a tight fit, but it clears everything just so:
