[W126 Coupe] Free at last

[richard jaffe]

Guys,

Finally got around to having the cats cut off and replaced with two sections of straight 2.25 in. aluminized pipe. So now I only have the two OEM resonators under the rear seat pans doing the muffling since I did not replace the old rusted out rear OEM muffler but ran split duals out the back instead. BIG DIFFERENCE! Acceleration definitely improved - now get that pushed back in the seat feeling as opposed to a leisurely gathering of speed.
Good sound too. Nice rumbly V8 noise - very muscle carlike - but not too loud.

Internet research led to a company in California called Spin Tech making mufflers for race car applications but now making street applications as well. They make a split case reverse flow muffler (inlet and outlet on same end) which is the same design as the OEM resonators. (C5 Corvette uses this design as well). The dimensions are 4"h x 9"w x 13"l which approximates the size of the resonators. So I'm thinking the next step will be to replace the resonators with the Spin Tech mufflers. The company claims superior flow rates and sound to competing performance mufflers (Magnaflow, Borla, etc..) so I assume superior flow rate and sound over the OEM resonator.

Anyway, its nice to experience these cars as the engineers intended - cat free!
