Yes those are the type of weights he is ordering that hang on the exhaust pipe. I hope that will do the trick. The size pipe I believe he used was 2 1/4 inch.
Thanks for the info.

Hello. I am new to CL. I have searched a lot on the site about muffler and resonator delete. I want to know first hand from someone who deleted the mufflers or resonators on a 95 or similar generation LS400 and if they had interior drone. I hate that drone when your cruising so any help would be really appreciated. If I were to delete the mufflers I would put still run pipe to the back like stock. Thanks again!!

I just did a 2 1/4" true duals with Flowmaster 40 series mufflers yesterday. My radio turned on at its normal setting, not loud but not uber quite, masks the exhaust pritty well. Personaly I would also add an x pipe to help eliminate the slight rasp it'll have. You can even add a small resinator on it later if its to loud for ya.

i first did the resinator and it was a bit quiet. Then swapped out the rear mufflers for more high flow., perfect. Then the all my mufflers were ripped off in an extremely deep puddle.... WAY too loud. I then put the front mufflers back on and it would still make my windows rattle when the car exhaust drone struck. so took it into a muffler shop and had it all rewelded . Perfect again!

I have a single glasspack (after the 3 oem catalytic converters) that runs to a 2.5" pipe straight out the back. Only on one side. I have been pulled over twice for my exhaust and I plan on putting another muffler on just so I stopped getting pulled over even though my car isnt even that loud. Trucks and motorcycles are way louder than LS400's but unfortunately be prepared to be heavily profiled by the police.

Hey guys! I've had my LS for a while now and a few months ago deleted both resonators and both mufflers. Car sounds kickass, but I now have a pretty enormous drone between 1500-2000ish RPM. It's awesome everywhere else except for that one solid cruising rpm range. Hear it all day, every day, giving me a headache.

Anyone know the best way to tackle this? I'm 20 and don't have thousands to throw around, buying $300 resonators, paying to put them in, finding out they don't work and moving on to the next idea. I've heard glasspacks and basic exhaust resonators don't do much for low-RPM drone. I know there are a lot of people on here who have straightpiped their cars too.

My car is a '91 LS400, I kept the exhaust completely stock except just basic muffler and resonator deletes. All 3 cats and the 1-7/8th inch piping are still there. I believe the exhaust shop used 2 inch pipe for all 4 deletes and filled in the spaces with some mig welding. I was thinking of trying out those clamp-on resonator weights that hang off the sides of the pipe, and also heard about "branch resonators" but apparently you need to know exactly how long to make the pipe extensions for that to work.

Anyway! Any ideas are welcome, and any experience from those of you who have also straightpiped your 1UZs. PS. My car straightpiped has no excessive raspiness or ****ty noise, it sounds badass. Best sounding V8 i've owned.

Straight pipe it but keep a pair of mufflers under the back seat to reduce chances of cabin drone.

Hodson

Would that happen to be exactly where the resonators used to be? I've heard chambered mufflers (such as flowmaster and thrush, although I would never put those sounds on a lexus) do next to nothing for drone, but magnaflows and such can do a good job due to their construction. Can others chime in with their exhaust setups and what kind of drone, if any, they get?

Hodson

I refuse to believe nobody else has this problem. lol.

Mine is not completely straight pipe, but a flow-threw design. I have a bad drone too, but it doesn't bother me that much. It's the worse around 2k rpm's. But it goes away at highway speeds where it sits about 2.5-3k rpm's.

I just deal with it... Your not going to be able to get a real loud exhaust and have little to no drone. You just have to chose what you want more. You can put like you said a chambered muffler on it to get rid of the drone, and still sound decent.

I have more of a glasspack style muffler and tips with resonators in them.

you got rid of the resonators, what did you expect?

throw a couple resonators on before the mufflers to get rid of the drone.

Hodson

Every other car i've owned to date has never given me so much drone after removing them, including the GT mustang I had (so you can't blame the fact the lexus is a V8)

I've read that in-line resonators will not remove low end drone, only high end drone. My drone is only from 1600-2000ish rpm. PS I have no mufflers either lol. My exhaust consists of the three stock cats and nothing else. I got rid of the resonators because they made the car sound like a bag of dicks, it sounded like a weird V6 echo. awful.

I was thinking doing Pypes M80 mufflers at the back where the stock mufflers were and seeing if that changed anything, but I've also heard adding mufflers can increase drone? And I don't know which design of muffler is the best for reducing drone, a straight-through style muffler, or a chambered muffler?
