nsxsupra...I don't mind noise, what about the JTC vs the LW?
Well as for GTLW vs JGTC, perfect timing for this question as we just did a test over last weekend at local nsx meet. If you want absolutely maximum rwhp gain, this is the exhaust for you.
I raced a 04 3.2L 6spd Imola Oragne NSX with JGTC exahust last weekend at local meet from 0~120mph with 4 nsxs following us, so there are actual witnesses, they are all prime members.
The 04 NSX had 2~3 feet jump as he slipped the clutch and lauched like bat out of hell, pretty darn good driver, I launched at 1500rpm on narrow oem tires, he could not pull even an inch away. By 70mph we was dead even, and I am actually starting to pull ahead, and stayed ahead until 120mph (I topped out the 3rd gear). We both had TCS disabled, confirmed with the driver afterwards. He also had that clutch smell. I did not slip the clutch, no smells.
Racing like that on the street was the dumbest thing we have ever done. I am thankful we both still have our licence, sometimes people do things without thinking twice. Next weekend we can probably try something safer 30~90mph highway roll.
I am 3.0L 5spd 92 with just GTLW exhaust and Cantrell AIS. 270.1rwhp is comfirmed not only on dyno, now also on street against 3.2L nsx as well in front of other nsx owners.
Sound wise, I took another NSX owner for a ride today. He said it is really quiet inside the cabin. It it oem quiet if you install the silencer that came with exhaust, absolutely zero cabin droning. Best of both worlds.
