first off im a proud new owner of a new RC 350 ![Woohoo](https://www.clublexus.com/forums/images/smilies/woohoo.gif)
alright ladies and gents, ive been bumming around the forum for some info about a muffler delete on my RC. i love the sound and like the 4" tips look. so the questions i need answered are as follows...
1. has anyone had problems with the check engine light coming on afterwards?
2. how has gas mileage been affected?
3. are there any long term affects on the engine as far as valves burning up or engine running lean?
4. How do those of you who have done it like it? do you prefer the sound over stock?
BTW this is my first post and im completely new to the Lexus brand.
Thanks in advance

Why not get an Ark Performance exhaust? Comes with 4" burnt tips or polished, gain whp, sounds good, and no check engine lights. :P

yes ZAM. it is illegal to do it in texas.... but im not worried about that, what i am worried about is the muffler delete causing problems with the O2 sensors and causing the car to run lean. lots of backfire, valve issues, ect.

Actively or aggressively enforced, no.
If no effort to quiet down the car is made, expect attention. That being said, J-pipes/Helmholtz chambers are an effective noise abatement tool where it matters most. (low end drone)
Low end is where you are most likely to get busted unless you decide to floor it in front of LE. In which case, you've got bigger problems than not having mufflers.

The cats and resonators provide sufficient back pressure, as well as mitigating the popping, crackling, etc.

The sound of the axle back muffler delete on this car sounds great....it will make no sound at idle and only a nice mean growl when you step on it. Post picks when you get done!

do you have a sound clip of the exhaust? or any pictures of the work done? id like too see how yours was done. and getting a blot on piece to replace the muffler section would prolly be the best way to go in case i feel the same way about it.

All I hear is deep and throaty engine when revving. Unfortunately 'clublexus' doesn't allow uploading video formats (mp4 or mkv)

Sound @ Cold start while i recorded crouching by the muffler. (this is as loud as gets before it starts to idle and you hear nothing)
cold start.mp3
Sound in Cabin with the windows down@ 2nd gear revved to 5200 RPM

Seriously I was going to ask him the same thing...i only did the axle back and it sounds nothing like whatever he described.
All I hear is deep and throaty engine when revving. Unfortunately 'clublexus' doesn't allow uploading video formats (mp4 or mkv)
so I couldn't get the file size low enough to upload the video. But if you want to see the video...just email me and I'll send it to you. Here are the audio extracts tho:

And I'll try to get a sound clip. To me it almost sounds the same as FR500GT, I just don't like that. It sort of reminds me of back when I use to drop the system off my skyline at the drags
