Speed Shop Welding
A look at what is currently available on eBay

Anyone else experience this problem?
I changed the mufflers on my 2006 Mercedes SLK with 11" Magnaflo Turbo units. After the install the car sounded great at an idle and slow and fast speeds. At 2200 RPM to 2400 RPM under a slight load they began to set up a harmonic vibration that was deafening inside the car. All mounting brackets and welds were inspected, and the muffler's had at least an inch clearance from any body surface. Nothing seemed to help.
I had the shop put the stock units back on and the noise went away.
Not unusual at all. Remember an exhaust needs to be tuned, no matter that the commercials on Speed Channel and the parts guys tell you. Go with a Lorinser exhaust and you'll have all the tone you want, added power and wicked tailpipes.
