HKS or AGENCY
I Need Info On Which Exhaust To Buy The Single Sided Hks Or Agency Dual W/ Titnm Tips. Wich Is Louder?which Gains More Hp?which Is Better In Long Run? Thanx

RX8 HA HA
hks single sided is made specifically for turbo rx8's so it'll probably work better if your turbocharged (gain more whp). If they were both installed on a naturally aspirated rx8 they would make about the same whp. You'll only notice a difference if you were turbocharged with the hks exhaust.

HKS has better build quality will last longer, but looks retarded on one side.
I'm not impressed with the Agency at all, tips are just riveted sheets. It hangs poorly and eats shrouds for lunch.
Both are 3 inches but the agency tapers after the "Y".
I have not seen any sheets on either but would suspect they perform HP wise the same, it all comes down to how well the mufflers flow.
If I had to choose between the two I would pick HKS.

oh ya! A company that makes things for Porsche is waaaaay too shitty for my RX 8 ... I'm sure they spent just as much energy as a Police man eating a donut when it came too designing the AP exhuast... And wouldn't less back pressure produce more hp? Why are people getting the idea that a single exhaust outlet would be better for a turbo?
I'll claim the cons of the AP exhaust though - >
- Melted shrouds (so you gotta pay attention if you start switching cat-pipes)
- Tips begin too rattle (so you gotta spot weld the tip into place)
- Tips might not look straight (so shoving some nuts/bolts into the hangars helps)
I'm thinking a single exhaust outlet wouldn't have the last problem I deal with... But why have a single exhaust outlet when the car's body is designed around two?

Both are 3 inch pipe and the agency tapers after the "Y" so it all comes down to how well the mufflers flow. The performance of the exhaust will prob be close to the same with a slight Edge to the Agency. A singe side exhaust saves on weight and some people are really worried about that.

HKS, Dual or single you can't lose. I agree with everyone else, excellent products and worth the extra cash. If I didn't have the vertex rear I would buy the Hi-Power single exhaust from HKS for the performance.

I'm surprized they did not compare it to the legamax since it is 2 3/4 inch. I would be curious of the results of that test.

i have the agency power. its nice exhaust. i dont like the tips that much because they are just bolted onto the muffler. Although the sound is quite nice. deeeeeeeep
