Hi Mahme and everybody:
Corsa exhaust installed this morning. Took Allen Cadillac about 2 hours, but it was the first one they've done on the XLR. (Perhaps they would have been quicker if I wasn't supervising and asking alot of questions.)
The mufflers and resonators are huge, when compared to the stock XLR hardware.
All welds looked professional, and included pipes, starting from from the catalytic converter, aft thru the mufflers and resonators, to the awesome looking, large throated, four tail pipes.
Cranked that "puppy" up, and WOW! Haven't heard a sound like that since my "Smitty" mufflers on my hot-rod, years ago.
The sound is definitely pleasing and, in my mind, puts an acoustic signature on the XLR that was missing.
Punching it, in both automatic and manual mode, allows you to hear the shift point, rather than just feel it, plus there is a lovely "burble" sound when you decellerate through the gears.
As I mentioned previously, I did not do a "before & after" dynamometer test, so I can't confirm any horsepower improvement, however, the car sure sounds faster and that's O.K. with me. I am totally pleased with the results.
P.S.
Have any of you looked at your XLR when it's on the lift?
I did today, for the first time, and was totally impressed with how clean the undercarriage was. Flat panels that covered voids, and just neat arrangements of hardware never noticed, including shocks and suspension systems.
Kudos to the XLR Guys.
I hope GM gets their Union giveaways behind them.
The XLR guys can't continue to function in that environment.
