Where did you hear it. Does it not sound like a Ferrari?
Besides, you won't have to worry about smogging your car for at least the first 4 years.

Btw, what part of Cali are you from? Are you going to the BOS meet next weekend?

I heard it at the AeroTect BBQ meet today. It sounds very good. As for it sounding like a ferrari... Ummm thats pushing it a little. But it does make the engine sound much bigger than it is... a True Ferrari exhaust... Tubi and such sadly I have to say sounds better. But then it might be a combination of the F car engine along with the exhaust that makes a Ferrari sound sooo dang good! I heard a one off a F360 and 355 before.
I'm From So Cal so no I wont be attending the BOS. Post back on what you think when you year it next weekend.

Nice thread- I don't know how I missed the original posting. I have personally heard this exhaust zoomin' by me on the freeway. I love the sound of it! I'm looking forward to taking a few more pics of it next time
Maybe even a vid or two....

Video / Sound clips soon.
I was talking to doug (The grey 350 with black crome rims) and mentioned that we needed to create some videos for everybody--not in Southern-cali lucky enough to listen to it in person. I think this will help the debate more--on whether you want to purchasing it or not.

After a slight delay in the delivery, the exhaust has finally been installed. It’s a stainless steel, true dual, CATBACK exhaust system with H-pipe, polished stainless at the rear section only. It is not smog legal due to the removal of the 2 rear catalytic converters. The front cats are still retained. The exhaust comes with two resonators.
![](https://www.clublexus.com/gallery/data/500/medium/Resonator_And_Front_Y_pipe.JPG)
Although this is marketed as a simple bolt on, installation is not as easy as you would hope. The fit was very tight, and has to be maneuvered EXACTLY into place. The front/H-pipe just bolts up to the front cats. The only tricky part about the H-pipe is removing the oxygen sensors. You will need to unbolt the stock front Y pipe from the cats and lower it far enough to use an oxygen sensor socket with a slit on the side to accommodate the wire for the sensor. You will not be able to use an open end or box wrench on the oxygen sensor due to the shielding around it. The mid pipe with resonators have to be slipped onto the front H-pipe and hammered into place. Be careful not to damage the flange.
The exhaust hangers on the mid pipe are designed to have one pulling up and one pulling down. This will hopefully eliminate the excessive movement the stock exhaust had. We were told by LMS that the supplied exhaust clamps are optional. It would also make removal of the mid pipe easier if/when you needed to put the stock exhaust back on. At this point installation gets trickier. You will need an assistant to help manipulate the rear sections to the proper location while you tighten the fasteners at the flange. This might take a couple of tries to get it just right.![](https://www.clublexus.com/gallery/data/500/medium/LMS_Mufflers_to_Resonators1.JPG)
Another little issue with my car is that the left tailpipe is not completely center, possibly due to the fact that I have the factory body/ground effects kit on there. The original test car did not have the body kit.
![](https://www.clublexus.com/gallery/data/500/medium/Off_Center_LR_Muffler.JPG)
One last thing, the piping for the left rear section will come close or come in contact with the big washer for the bolt on the sub frame. You will need to loosen the bolt and turn the washer so the tang on the big washer clears the piping.![](https://www.clublexus.com/gallery/data/500/medium/Left_Side_Hitting_Subframe.JPG)
A baseline dyno was already impressive with horsepower readings of 254.6 (to the wheels) and torque of 223.6. Readings after the exhaust showed maximum horsepower of 263.7 and torque of 236.4. There were reported gains of 22 rwhp. This however was reported with a prototype. I know for a fact the resonators had to be redone (due to the fact that they were too loud), and I haven’t seen any other dyno sheets with the production model. Depending on many variables (different dyno machines, temperature/humidity, etc.), the results will vary.

Sound: Unfortunately I do not have any sound links. Definitely growls on WOT and when you romp on it to about 4500-5000 rpms. If you are just cruising, it has a nice low grumble. Of course sound is very subjective and since I’ve been around modded cars for over 20 years, I don’t consider it loud at all. For others that are not used to it though, they may consider it a little too much. I was concerned that it might sound tinny or ricey, but was pleasantly surprised when I heard it in person. All the sound clips in the world will not provide the real world experience.
Personal opinion: I love the way this exhaust sounds! Just throaty enough and without a lot of resonance. Kind of reminds me of how a Ferrari sounds! If you are worried about smog checks, etc., you will have to decide on your own whether or not it’s worth the trouble. New cars sold in California do not need to be smogged for the first 4 years (unless there is a change in owner). Therefore, I’m gonna have at least 3 years of very vocal driving before I have to worry about that. I wasn’t too concerned with the round canisters since you can hardly see them anyway. There’s just enough shine peeking through to let you know it’s not a stock exhaust.

Keep in mind that this is all for informational purposes only. Everyone will have their own bias or opinion on whether or not the cost justifies the gains or aesthetics. A lot of members have tried certain products and found out later that these products were not worth the time, money or trouble. It’s those members willingness to use their cars as guinea pigs and provide feedback to the community at large that makes these forums invaluable when deciding what or what not to do to your car.
BTW, the car has also been lowered (slightly) with the Eibach Pro-kit . They were put on about a week after the exhaust. Didn’t want to take pics right away since I was waiting for them to settle.

For those of you that live in Northern California and would like to see it and hear it in person, stop by the NorCal Beginning of Summer Meet (https://www.clublexus.com/forums/sho...d.php?t=217857). So far, I’m the only Matador Red IS showing up, so it should be easy to spot me!
