Thanks guys for the feedback.. I thought the V12 MIGHT have had something to do with it..
I'll have to play with my exhaust one the thing rusts out.. or may be even just tool around with that ol' "tuned redneck" sound. hehehe

For me the best sound in a 928 (especially from the driver's seat) is the cams in a 90 GT with the stock exhaust including cats and an RMB. Just seems to have a musical note to it.
Spectators at our local PCA autocross say my GTS with x-pipe, sport cats, and RMB sounds better than the V8 vantage that comes to our events. I don't feel my GTS is as musical as the 90 GT was.

yeah but when i let off the throttle with an Xpipe and a RMB with the fuel cut off disabled i get the most wonderful gurgling and poping sound. You can just hear the Phwupp phwup....phwup bup..bop.
I really need to record it....it really sounds great and intimidating!
on a stock S4 the fuel is shut of under deaccleration but with a Sharkutner you can disable it. Worth the price right there
there are a few DBS's around ehre that i have heard. Sounds wonderful. Then you hear the BMW M5 with a tuned exhuast!!

BMW went one further and actually put a resonance tube from the exhaust manifold to the firewall on the Z3 or Z4 (forgot which one) to enhance the exhaust note in the cabin without making the car any louder to everyone else.
Me? I just remove the mufflers
My 81 has a tiny borla straight through after 85/86 manifolds and no CAT. My 79 is MSDS headers with a straight 3" out the back.

Do you remember?
I agree, and would add that timing has an impact as well. When I bought my current GT, even with the RMB it just didn't sound as good as the red one you and I once owned. The Hammer showed my new ride had faulty knock sensors and Hall sender, each of which would retard the timing. After doing an intake refresh and attending to these items, the glorious music was restored. Much crisper sounding now!
What was/is your per 10,000 knock count before/after you placed the sensors ?
Thx

Hi Herman - Unfortunately, I do not know as we never drove around with the Hammer hooked up. All I know is we were getting fault codes for the knock sensors and Hall sender when hooked up in Sean's garage. Given the default safety settings when these items fail, I would expect the knock counts to have been few, if any. Certainly thottle response and overall power, as well as the exhaust note, were noticeably improved afterwards.

You haven't heard my GT3 with the Sharkwerks center-muffler bypass; sounds very angry, especially from 5K to redline.
My '91 GT with X-pipe and RMB has a different sound that I really like too.
