Default Re: Supersprint Twin Pipe exhaust sect.2

What an excellent thread to see today. So glad to see this finally come to market. I can't wait to get mine...and my SS Resonated X-pipe doesn't even have an oil-change interval on it's life yet.

Thank you gents! Too soon for me then :-)

That's a much better guess considering the resonated 3" single section 2 is $900.

Unless they offer a sweet introductory group buy, no way this is under $1k.

Granted I don't really care. I'd be happy with a grand, but hoping for sub-$1500.

So really no benefit if you donít have cams or a csl intake.

What's the difference in sound between the two?

The H-crossover seems to be where at least half of the S54's rasp comes from.

OK so who wants a resonated section 2?
As nickpiper mentioned, i'd say other way around.

From what Iíve read, the s54 rasp is due to the sodium filled exhaust valves

Interesting. I did not know that. Would love to read more about that if you recall the source.

I thought a lot of the rasp also had to do with the dual piped exhaust design and the firing order of the motor (and thus exhaust pulses in each separate pipe -- which is why it's only heard at certain RPM (aka at certain pulse "frequencies" as the gases bounce off the walls of the 2 pipes)? Isn't that why the single exit exhausts on this car seem to eliminate that rasp entirely?

...I could totally be wrong on all this, which is why I am asking BTW.

I can't tell if you were being serious. Only the CSL had the sodium filled exhaust valves. Standard M3's are not.
