I have tried looking everywhere to get information about the RE-Amemiya dolphin tip exhaust but besides people knowing where to get one, obviously from the re website, i have found no information about it. We all know that the RB exhaust sounds sexy and gives really good performance cause of the one pipe to one rotor set up but i cant get over the fact on how heavy the exhaust is.

It would be stupid to assume that the RE exhaust is better than the RB exhaust just cause RE uses their cars for time attack and RB exhaust is mainly for street use so that is why im asking this question. How does the RE exhaust differ from the RB exhaust performance wise? Which one is better? Hopefully someone that actually owns a RE exhaust can clear this up for me.

 

EVERYWHERE, huh? 5 second search. FIVE. SECONDS.

I think he was looking for more along the lines of weight and owner opinions.

 

The RB is probably the most conservative aftermarket exhaust, and some would even consider it a high restriction compared to anything else.

Hopefully that's the answer to your question. Plus it looks stock, which helps in California.

 

Yeah... I think you're right. I was a little blinded by the fact that "this exhaust, that exhaust" threads come up SO often.

OP: your purpose for the car can have an impact on your decision. What do you intend to do with the car? Are you satisfied with stock power levels or do you have a hp goal? How do you want it to sound? If you know things like this it could help people steer you in the direction you'll be happiest with.

 

I dont know about restrictive, its full 3" all the ay to the 2"-3/8 split. All I know is that its nice and quiet when cruising at 3krpm. And by quiet, I mean quiet by rx7 standards so no ear bleeding from the dreaded 3krpm droning....

If its not loud enough for you, you can easily put a straight pipe in place of the resonator.

 

Well heavy weight is a relative question... Stock manifold/cats/catback vs full RB.... Pretty sure you're saving weight there.

RB's exhaust is excellent, and you can certainly feel the power increase [even on my S4 NA with stock ports when I went from RB header/presilencer+stock catback, to an RB catback]

As for asking what's "better"... That's ALL opinion. I think the RB is better because it looks so nice, performs well, is much more durable than stock, and is dual [I hate the idea of a notch on one side of the bumper when it's clearly designed to have exhaust under it]

Purely performance-wise... The RE probably has the edge.

 

I have already seen that video and the only info i get from it is sound. Im looking into more of a owners opinion on the exhaust.

so is there anyone on this forum that has a RE exhaust that can boast about its performance?


i concur there are ALOT of threads about the COMMON RB APEXI HKS ETC exhausts but there are no threads about someone reviewing the RE exhaust. as for my car im planning to dd and track it. i dont have a hp goal cause im stuck with stock ports until i get money for a rebuild and i dont plan on getting a turbo so weight reduction, intake, exhaust are my only option for now. im also planning to really work on the suspension cause i like how it feels when it gets really tight.

 

rhdjapan.com has the RE exhaust as well...since you mention money, the RB exhaust is a lot cheaper.

Also, I don't think you can buy individual components for the RE system, where as with the RB, if something happens on the track or driving around that damages the exhaust, you can buy individual pieces.

The RE does have the edge of being "rare", but you didn't say anything about it being a show car and rarity means jack on the track (or with the girls I go with ).

 

Just make your own:

Borla XR-1: $120 ea
3" Y: $90
Misc bends/piping: $250
Having a badass dual exhaust that's actually full 3": priceless

I myself have the RE Amemiya dual exhaust. It's 3" all the way and looks stock and quiet. Unfortunately it's no longer made and I think only 3 people have them here.

 

whoa 3 inch dual exhaust? nice. do u happen to know the usernames of the people with the single dolphin tips? hehe

 

RE Amemiya only offer a single exit (usdm driver side) stainless steel cat-back. No longer offer their titanium. Their dyno result, with a cat, shows 5-10 ps increase... You do the math. It's made to meet Jasma spec, it shouldn't be too loud if it's street legal. IMO, you're paying for the name. It's way too pricey for a cat-back, shipping from over seas will kill you.

I've had HKS Hi-Power, Apexi GT-Spec, RB, RE A. Ti. All in all, I think RB has the best quality base upon fitment, durability (the extreme heat from these engines will kill your thin wall pipes), visually, and not to mention you won't get harass by law enforcement.

 

i think the rb N/a exhaust only adds about 7 hp. thats what it said on their website.

hmm ic but lets not take sound, durability, and looks as a factor but hp increase.

which exhaust, from your experience, felt like it had a more significant power increase on the engine?
