I've been reading these forums since I bought my RRS SC back in March. And I found a lot of post about single mufflers with dual in/dual out. But no one seems to be running a dual setup with single in/single out per side. I'm really interested to find out if anyone is running this setup regardless of muffler brand. I only ask because I've been quoted this setup from Platinum Motorsports in LA which uses the single in/single out mufflers per side. They say it sounds better and a few other name brand shops have told me the same thing. So, is anyone out there running this setup? Thanks

Have the guys at Platinum Motorsports given you an indication of what you're likely to achieve ? Or did you just ask them to make a specific setup on your ride !

Here's a simple method of measuring and assessing your current situation versus your future "option" in terms of using their suggestions and recommendations.
Measure the outside diameter of your (model year) RRS S/C exhaust system pipework and then use the following equation Q = v.a [ Discharge = velocity x area ]

Some of us mere mortals can describe how your existing exhaust system performs (poorly) and how individual / custom installations have shown improvements.

What I'm trying to achieve is sound quality/loudness which I understand is subjective to the listener. All I want to know is if anyone has this setup on their truck. And no, I did not ask Platinum Motorsport for anything in particular. They just looked at my ride and said that's what they install on all Range Rovers they mod. They also use Sebring mufflers.

G'day Vinni.

Fyi. If you don't mind, I just forwarded this formula over to some folks I know @ BP.

No worries Goosey Loosey.

Please forward this one onto those girls again at Exxon-Mobil ? Apparently they're still trying to work it out in Alaska & Obama's been looking off the N.J. Coast !

I've witnessed a few 'Sebring' mufflers in my time and they make an awesome product, including that Austrian crowd as well who are specialist exhaust builders.

Ideally non-supercharged engines require the least back pressure to aid "exhaust pulsing" versus the turbocharged brigade that need some efficient resistance.
It's hard to understand and treat your inquiry in isolation compared to Platinum Motorsports response, but what the heck - give it a go in the good ol' U.S. of A.
