LS460 Muffler Delete. Finally!

Pole Position
Hey Guys,
I considered cutouts at first, took it to my mechanic, said there was no room to put them.
I am aware a few members were successful with cutouts on the LS, not me.
I finally went with the muffler delete, and I can say I am very pleased. Sounds to good.
Here is a clip.

Jumped on the bandwagon
I got excited about the sound potential of these cars after listening to a few of these muffler delete sound clips. So I went with the muffler delete. Never did like how quiet Lexus makes 350+horses from a v8 sound anyway. Anyway did the delete and added straight pipes out of the back. The sound was so awesome but the drone was so intolerable. Drone was from 1500-2000 rpm, with peak right around 1700. So back to the exhaust shop to get a j-pipe placed. Used the helpful chart posted here. Went with 29" j-pipe. Could not be happier. Drone all gone. Nice deep tone. Not to loud in any condition for my ears, although I understand that is a purely subjective statement. Best way I can describe the volume from stock to muffler delete is in these two examples. First, With the stock exhaust, I could at slow speeds putting around the neighborhood, clearly hear the annoyingly loud fuel injectors. Now that injector noise is very muted, as exhaust volume has gone up. Second example, with the stock exhaust, when letting off the gas from let's say 40mph and coasting up to a red light, I would hear...well... not much of anything. Tire noise I guess. Now when performing that same coasting I can hear the exhaust note clearly go up and down with each downshift of the transmission. I would say this exhaust modification has added to my driving satisfaction of this car. Cost was 100 to cut off mufflers and put on straight pipes. Cost was 200 to fabricate and weld on j-pipes. Thanks to all of those who have commented on this modification, both for and against it.

i now drive a silent Tesla, but i still have an exhaust dump which can be used to go from quiet to loud quickly if anybody is interested (PM me)

Hey all,
Yes I do think for most people looking for a bit more growl in the exhaust, the cutouts should work well. However I was shooting a bit higher to hopefully yield more sound than I believed the cutouts would provide. Yes I went too far and got drone, and paid the price both literally and figuratively for j pipes but it was a good experiment for me.
One thing I refused to do was play the cat back exhaust game. Didn't want to buy this system for X amount of dollars, and not like it. Same thing with mufflers. Didn't want to play that game of buying and trying all the different brands. Too costly, too time consuming. So for me the straight pipes and j pipes worked well.
Concerning resale, not too worried about that, but I did have the exhaust shop owner cut off mufflers in the best possible (read easiest) location to weld them back on if needed. So there the mufflers sit in the shed.
I"ll try and shoot some pics or video or something. As you can see from my posting status, I still have the training wheels on.

Just want to share a few pictures of hacked up/modified stock exhaust systems from Yahoo Japan. These must have some good HP gains as seen in ISF/GSF threads. I like the idea of losing the secondary cats but not sure about using the factory H pipe which is even moved forward in this set up.
This one also uses the factory down pipes with what looks like a 3" center section.
Another with no secondary's or resonator must be loud.

man that sounds amazing
Some cars just don't sound very well in their raw state , but these do
I drove a straight piped supercharged corvette for 2 years and drone never bothered me so I don't see how the 460 with all its sound proofing could be an issue
I think thius mod only wqorks when your car is modified visually to some degree (lowered, wheels, body kit etc...)
On a stock car it will look foolish

Exhaust mods and intake mods for me has never been good Idea on a Lexus. All it does is make me drive more aggressive just so I can hear the sound all for a tiny bit of horsepower. I think the muted V8 Lexus is just enough for me to enjoy. If I want to hear some V8 muscle, I just shift manually and high rev & I need to turn the radio off
