it's called hearing loss from the mod.

no way i'd ever do this. in fact, i took out the 'sound booster' snake pipe under the hood that blasts sound into the cabin at higher rpms. still plenty loud enough for me, but no on/off louder.

 

(Just jerking your chain! )

 

LOL.. that's the problem Gibbons. It's not loud enough at higher RPM's now.

 

you mean its quieter at high rpm's with the mod than without ?
i believe at high rpm's the exhaust is wide open regardless...
the mod would effect your low end rumble ...

 

yes, so 100% idle to about 4k rpms, the exhaust is loud. You hear crackles, pops when you take your foot off the gas.

what i'm missing is, the whaling and screaming sound i love so much. 10-25% throttle input, between 3.5k RPMs - 6.5k RPMs. I'm no longer hearing that, and also missing the WOT grunt you hear from the exhaust all the way to redline. Ever since i got the car, i've been keeping my throttle position in that sweet spot i love so much, Heck, i literally only drive the car in that RPM range. I thought i was very familiar with how the car sounds in that range, but today it was totally gone. Maybe it was the wind (loud), but i'll try taking it back out tomorrow to see again.

 

ha, one could also say if it's too quiet you're too old as well because you can't hear it!

 

yeah you definitely get a rimshot when you take your foot off the gas; and i know what you mean: at around 6000rpm you get an induction whale above the roar of the engine that is beautiful, F1 like...but risky for my license.
you should try your connection hooked up and see (hear) how the sound differs, and if it is restored....lexus engineers may have the sound tuned that is disturbed when you mess around with it (as in duh ! ) ....

 

our friend DRGibbons states the sound will be S+ like at all times with the mod, which i find appealing; however, conflicting reports such as yours bear a little caution...till we pull the plug.

 

When I first got my LC, I did the mod & unplugged the connectors. After awhile I found it annoying with the exhaust open all the time. I reconnected the plugs & when I want the extra growl I just select Sport +. Plus when you unplug them you have to make sure sure you protect all four connectors or they can corrode.

 

and that's the thing, it does not resemble Sport + mode at all IMO.

I actually plugged everything back, prefer this setting and would rather drive in Sport + mode.

 

I cut off the tips of gloves and covered them, then taped them up.

 

With the valves unplugged (modded) they are in the same position as Sport+ - wide open. What is probably the difference you are hearing is there are some fuel injection and timing changes made while in Sport+. Try leaving them unplugged and selecting Sport+ and see what you hear. It should be what you remember from Sport+. What you will notice is that in the other drive modes it will consistently be louder than before. Also remember, in Sport+ the transmission will shift differently and it won't shift up past 6th gear.

 

it's not, i saw zero change when they were unplugged and i switched driving modes. It's rather a moot point now, as I plugged them back in.

 

i think it's 8 gears in sport / sport+ ?

 

This whole issue goes away and you get a glorious sound 100% of the time no matter what mode you are in if you do as I did!!
