The resonance was with the stock exhaust, not the Sharkwerks.

 

Hey NSXTC, it's interesting you found that out. Another customer told me the same thing that when using our bypass system and unplugging the byapss there was no resonance where as with the stocker that you did actually get resonance. Strange and I'll need to try that... If so that'd be a cool and unintentional benefit

 

Hey Alex,

Yep, no drone whatsoever with your exhaust w/ valve unplugged. You'll definitely get a much better sound < 4000. It's sweet. With the valved plugged, it sounds almost normal. You gotta try it man! It should be mandatory for everyone with your bypass.

 

Yes sir...the stock center muffler is what causes the drone...go figure.

 

looks like I'll be unplugging this "flapper valve" again this Friday. Before Sharkwerks bypass it had too much resonance. will let you know how it sounds.

 

That is interesting.. Going to try it this weekend. I drive with it open all the time anyways and it's annoying that it wants to revert to being closed all the time

 

alec: what about 100-200 cell cats in addition to the bypass? did you try the bypass switch yet

hey tom, honestly we've tried different cat solutions and for anyone that goes to the track... it's _very_ likely they'll come apart on you. Very I'd say keep 'em stock. It would need retuning for that since the back-pressure changes quite dramatically as well.

Hey guys, this third batch is going out on Monday/Tuesday and I'll pm you guys the tracking etc... Thanks again!
