S1 Soarer if your ever in the Newport Beach area you can check mine out. What i did was take the resonators out, put in a magnaflow right behind the cats, then straight pipes out. i think it sounds amazing. i was a little iffy on the idea, but way happy i did it

I tried with the mufflers and resonators off and it was terrible, I would not recommend it. I Just deleted my mufflers
if you are looking for a g35/37 sound then just get free flowing mufflers and call it a day.
with the set up that I am running (2.25 in piping straight from the resonators back) I am louder than a mustang GT and it does attract some attention, but it has never been from cops (knock on wood). but I have gotten a lot of looks like "is that sound really coming from a lexus?" Almost everyone who has heard it, including my father that usually hates exhausts says they like it and it sounds like a V8 should.

Did you add resonator tips on the back also?
I have heard straight piped cars (muffler delete) that made a "popping" sound that did not sound good. Your car seems not to have this problem.
If you ever get a chance, please make us a new video of your exhaust sound. Maybe sitting still revving?, as well as an in car sound when driving down the road?
Thanks and Great Job on your SC!

The best to have a nice sound with hp gained is to have the stock exhaust system replaced with high flow cats, resonator (recommended), and high flow mufflers. Also run dual 2.5" for the pipes. Most pro-exhaust shops can make a new system for less than $500. You don't need headers if you're on a budget.

The SC430 is just a nice refined luxurious convertible cruiser, all I am looking for is a slightly throatier exhaust note, the stock power is definitely enough. I don't really care for the 5~7 hp gain from a full high flow exhaust, I can't even feel that.
If, when I am looking for a fast car, I will buy a R35 GTR, exhaust/turbo/race gas/tune would give me 650 whp, that is a rush I can feel!

Now a days, I want to keep the car as OEM as possible, I am tired of inferior aftermarket parts. I have tried the best and most expensive aftermarket parts, and most of them are still crappy

I just posted a before and after video of my SC430 with and without the Injen Short Ram intake. They're short but hopefully it helps those that are interested. What do you think?

I finally did it, I had the resonators removed from my SC430, here is my report.
The growl got noticeably more throaty, it definitely got louder. But that is comparing to the almost dead silent stock sounds, I say "almost" because my stock LS430 is dead silent, the stock SC430 is a hair louder.
People are right, it is still too quiet for a weekend car, I would probably leave it if the SC is my daily, this is a good setup for a daily where you don't want it annoyingly loud in your commute. I would say it is still a hair quieter then a stock G35, the stock G35 is pretty loud for a stock Japanese car. Now I can mainly hear it when the top is down at low speed, when speed increase, wind noise drone it out and this motor is weird in the sense that it get quieter as it revs up.....too smooth maybe? With the top and windows up, there really not much difference in sounds, this car is so heavily insulated, it needs a lot of volume to be able to hear it inside the cabin. This is the hard part, I want it loud enough so I can hear it inside the car without it being embarrassingly loud on the outside. This is why on the LFA and late model Mustang, they channel the intake and exhaust sounds with tubes into the car so it can be heard inside.
The sounds is really sweet though, small displacement V8 sounds good, now I am hooked, I need to make it louder. I will try removing the stock muffler and put the stock resonators back on. But that set up might have a chance of being too loud for me, if that's the case, I will replace the stock resonators with a bigger straight thru high flow aftermarket muffler. My goal is stock looks, I loves the looks of the stock exhaust tips, I don't want that aftermarket tuner looks.
