Apexi active tail silencer with HKS Hi-Power exhaust on RX-8

[Ivazor]

Omg that BOV is amazing! Such a nice sound :))

[pass1985]

What is the dial on the right? what do the numbers mean? The one on the left is boost, correct?

[WaxOff510]

fit*

[WaxOff510]

howd u manage to make it hit into an hks hi power? Correct me if im wrong but the hi power exhaust tip has 97 mm diameter while the silencer was made for 90 mm...soooooo did u just stick it in there anyways? (thats what she said) and if so is it loose?

[garmool]

did u lose hp with the silencer?

[papiloma21]

it works! I think its better than borla. but I dont understand what could be the purpose for silencing such an awesum RX8 ?!?! if it was up to me/if I were u, I wouldnt silence it....rotaries r generally quieter than piston motors & I would definitely show off n want people to notice me n my ride if its an awesome sports car, the RX8

lolz!! funny text at 30seconds !!

[tyrannical]

A rotary engine is VERY loud.

[333headshot333]

@papiloma21 lol the rotary is one of the loudest powerplants in the world.

[jimmybrite]

I thought the Hi-power was a quality exhaust? so much for marketing.

[wasim18m]

dos it make a lot of diff wen u put the silencer cuz i want to geh one and i dont want too much noise until my dad goes wrk nd then am gona take it out :)

[Da1RiSiN1sMoKe]

Who cares about it?

My dad loves my loud exhaust.

It should be about what YOU want for loudness.

Most silencers take away about 8 decibels.

Not a lot.

[ryanazarko]

most silencers take away about 7dBs at most, and that IS a lot.. remember 93dB vs 86dB is not an 8% reduction in volume, its a logarithmic scale. Regardless, tunable silencers are usually 1dB to 6dB reduction, and auto silencers are less than 5dB reduction.

[klauskarlkraus]

you are doing great work on your rx-8 but you must have too much fucking money i could never afford all the tuning.

[95MonteCarloGuy]

lol as it runs over the camera

and also...i dont mean to offend you tyrannical, but i think it sounds like a ricer =[ me no likey...nice car though =] lol

[tyrannical]

long since changed exhausts.

[puertoricanEX0]

is the whisle cummuing from the silencer? or thats the BOV???

[tyrannical]

yeah, bov. would be stupid for the exhaust to whistle.

[MRR8746]

what's kind of bov is this ?

[iiJeebz]

Still sounds pretty loud at low revs? Mind you, a rotary is pretty loud anyway :)

I'm considering getting one of these (for an R34 GTT) but am not sure whether it'll do the job or not. Might be better off getting an XForce Varex muffler perhaps.

So in your opinion, no loss in performance, any affect on the turbo?

Cheers

[tyrannical]

I didn't like it being in the exhaust flow. I don't want to claim loss of power or anything since butt dynos are usually inaccurate. I would have to had gone to a dyno in order to tell you the answer. Which I didn't. Personally, I don't recommend it

[BartleyNorman]

AHH>> Now I have to get the Rx-8.. with the turbo kit. I know my brain says the Rotary is AWESOME> SO SMOOTH..

Bartley

[kulluminati]

tyrannical, could you please tell me does the silencer affects much the turbo charger? tnx

[tyrannical]

I didn't get it dynoed, so all I can do is guess at how much it effected things. I don't use it anymore, and I don't know if I would recommend it either.

[screamingdemon]

Ok well I've been thinking about getting this type silencer for my N1 catback that I've got on my Eclipse. I was wondering is it only loud under WOT and how does it sound with say just half throttle? Is it much louder than say stock when you're not mashing it? Thanx.....

[tyrannical]

hard to say, since the stock exhaust is very quiet, and the hi-power is extremely loud. I would say that the sound is roughly cut down by half or 2/3rds in the low rpm range, and full volume at WOT.

[screamingdemon]

Ok, thanx for the info. I guess I'll be investing in one of these silencers in the near future to try it out and see how I like it.

[Pr1nceTone]

What kind of turbokit do you have? I want to order 1 for mine

[jino2sys]

What blow off are you running?

[tyrannical]

this video has a Greddy Type-S BOV. Check my other videos as I have 2 others.

[jimbo888]

so the ATS fit the Hi-powers exhaust tip , thinking about getting the ATS , just got pulled over( i have a hks HI-power as well)

[tyrannical]

No, it doesn't fit. The ATS needs some modifications to work. Since I'm not using mine anymore, it's available for sale and will be a drop in fit.

[lalalalay]

sounds awesome!!! since the sound proof work, what about power wise? does it still pull as hard as when you didn't have the ATS on? again very nice.

[tyrannical]

i removed the apexi silencer. if I was NA (no turbo), I think I'd have kept it (added back pressure at low rpm, free flowing at higher). But with the turbo, I prefer the exhaust without it.

[bokiss13]

thanx, thats what i wanted to read ,-)

[tyrannical]

Without a doubt the Borla has a nicer note to it. But the HKS Hi-Power flows better. I think the muffler is just glasspack, which is why it's so loud...

[rankore69]

Sounds nice >:) ...so you prefer the borla then?

[tyrannical]

the tin sound from the hi-power has gotten a lot less, so it's nicer now that the inside of the exhaust is covered with a layer of soot... I still think the borla sounds nicer, but this exhaust flows better

[barbershop4]

i agree i have a honda civic and i put a borla 3 1/2" titanum exaust system on it with headers and aem intake...i also done other things....but i love the way that turbo sounds....ima get one soon but i dont think ima go with greedy.....why did you put the silencers on you pipe??is there a law for it being to loud in fl?

[tyrannical]

I don't want to drive around like a spaz with a loud ass riced out car. I don't mind loud at high rpm, but loud at 2k rpm is stupid. I have since gotten rid of the HKS Hi-Power exhaust, so I don't have the silencer anymore.

[barbershop4]

thats kool....my car isn't to loud in low rpm...but sounds really good at about 4k-8k rpm..so do you race?? and you should post somemore vids up..i think your car is awsome....and im sure other ppl would like to see you burn some asses lmao....
