it comes pre burned..but you should see it now...the whole tip is either blue or purple. Yes i fabricated the screen myself. from behind the old outlet looks blacked out

 

Just to clarify this (I'm sure XDEEDUBBX knows this). One or two mufflers don't matter much except for looks and weight. The HKS makes more power because it larger piping and a less restrictive muffler. If they wanted to, HKS could add a second muffler and make it dual and still make the power. I belief Trust (aka GReddy) now makes a dual muffler setup with 70mm piping.

FWIW, I like the HKS and the single outlet. More purposeful. Sure the car was made with duals but that was just for looks. Function over form for me

 

In therory a dual muffler system would be less restricitve. But like you stated it all depends on the mufflers.

 

flow isn't a huge factor for the RX8 because the exhaust ports in the engine are what is restricting it, not the exhaust. Deleting a cat will free up some horsepower, but just replacing the exhaust system won't yield much hp, which eveyone on here knows.
The main benifit of a single system is the weight savings. Obviously one muffler, no Y-pipe, and less piping overall will weight less.

And labdad- HKS does make a dual exhaust system for the RX8 called the Legamax and it retails for $990.

 

sorry to let you down chicken, but i did not know that, i feel so ashame, i must take a cold shower now.

 

XDeeDubbX ,

Those are some nice shots of your car, and the single tip with your modded block-off look pretty good. Have you taken any other shots showing the entire back end of the car with the single exhaust and block-off screen? I would like to see how that perspective looks too.

As far as the Legamax goes the pricing has just recently dropped per a discussion I had with a vendor, and I have seen the prices in the $830 range, which makes it a lot more affordable even with shipping than previously. Of all of the sound clips I have heard, I really like the sound that the HKS makes.

 

Yep, I know about the Legamax it has 65mm piping while the HiPower has 75mm piping. I was just wanted to point out that the HiPower flows more because it has larger diameter piping which is more important than if it has 1 or 2 outlets.

All this doesn't matter much if you're NA. As you've pointed out, they already flow more than needed. However if you've got a turbo or are planning to turbocharge. I'd recommend the HKS Hi Power.
