A car with many exhausting tales...
My '01 740 i Sport now has 32K miles and a one owner but it has had many exhaust systems during that time.
First it was OEM for about 2 years - then first came Remus from the center resonator back....cut the bumper for the rear exits.
Then I added a custom rear bumper - e39 M5 type...
Then several years later I decided to remove the resonator and install a cross over - too NASCAR, lasted about 30 minutes before I took that off and replaced with MagnaFlow resonator with internal crossover.
That lasted several more years as it sounded pretty good, nice tone for a 740. Then I grew tired once again and needed a change. Took off the Remus and made everything from the cats back 3" pipe and installed my OEM mufflers that I had opened and removed all the baffles and replaced with a perforated pipe from inlet to exit.
That lasted about 6 months - not happy with the sound but not too loud or droning... Next I decided to replace the 3 " pipe as I felt that it was too large and had caused some of the bottom end loss of performance, sluggish.
Next I dropped to 2 1/2 pipe and crossover with two Gibson chambered mufflers - this was too loud, droned and just sounded bad.
Next I added two resonators - one in each leg between the crossove rand the rear mufflers. That didn't do much at all......
Finally as of today it now has 2 1/2 pipes and a "kissing type" crossover with two E63 M6 OEM mufflers....have not driven yet, raining cats and dogs, so test drive tomorrow I hope. Sound is good at idle and constant rpm , a little raspy when you let off...we will see!
Fini....
