HI All,
I've just recently bought RX8'04 A/T model, need some input on accessorising especially the exhaust. Can you Guys give me some input, I'm considering Fujitsubo Legalis R and HKS Legamax, what do you guys think, in terms of performance influence, fuel efficiency and increase in Hp.
Thanks Guys

 

Increase in hp? Heh.. I'd get the MS exhaust.

 

welcome.

Really the only huge differences in cat-backs for the 8 are weight and sound... (price too I guess)

performance: little difference
fuel economy: not much difference
increased hp: 5 maybe... if you're lucky...

read stickies, they're useful. there's a sticky in the aftermarket section called aftermarket exhausts summary: https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/rx-8-aftermarket-exhausts-summary-16442/

Best thing is to look at price and figure out the sound you like. I have the racing beat dual exhaust with RP supercat but now I'm kinda wishing I had the HKS single cause it has a nice sound and added bonus of being much lighter. Good luck finding something.

 

welcome to the forum, theres no HP to be gained from exhaust, maby 2-3. \


please use the search button at top of page, theres a lot of great info in the forum, reading it all would not hurt, 90% of my knowledge of my car i got from this forum.

enjoy the car, mod it with what you like.

 

Thanks Guys,
I've read most of thread already, bust I haven't found anything for Fujitsubo, most of what I've seen so far is HKS, RB, or Borla.
Since I'm driving an A/T is there any specific Exhaust that I have to purchase or they all goes bothways, I mean for A'T & Man6

 

i dont know what im talking about. honestly i joined the forums a few weeks ago. but im pretty sure all the aftermarket exhausts start at the midpipe. they dont bolt directly onto the engine manifold. or w/e its called with rotary engines. so that means any exhaust system fits any 8, whether it has the 4 port (AT) or 6 port (MT) engine.

 

yes, all current systems work on a a/t

 

When I first got here, I found this thread very useful.

Best performance mod for an AT... trade in for an MT.

 

I am afraid a free flowing exhaust system will kill the low end torque event further, especially for A/T car.
