HKS sedan exhaust
I know there are a few people on this forum that have the HKS exhaust on their G35 sedans and i was wondering if they could share thier thoughts about them. I am very concerned with the sound comapred to the stock setup. Is it deeper, more agressive? I hope it doesnt sound ricey. Also, is it worth the money, or is there a better exhaust out there?

Re: HKS sedan exhaust
do a search on HKS and you'll get a few. I believe Ryoken has one and loves it. Said it's not much louder than stock. Gives it a growly european Sports car tone.

Re: HKS sedan exhaust
I have one. I was going to do the coupe mid-pipe too but I decided not to. When I first started the car it was really quiet but when it warms up it sounds verrrry nice !!! Not high pitched like the coupe or FX, not as musical as a Ferrari or Alfa, but a good growl that builds to its max at about 3700 rpm. After that it gets quieter and the Z-tube/Pop charger take over. Just cruising it is not obtrusive and has zero drone. Although I hate it when my wife takes the car, I just love hearing her drive away. I can even hear it from inside the house when she "gets on it" !
It also looks great. Two round pipes and all polished stainless. Very high quality and looks like what the car SHOULD have come with.
All in all a really good mod. There are no flow advantages from the coupe midpipe and the sedan mid section may have some important aerodynamic advantages. I may get a Y-pipe in the future, but not until the prices are somewhat less "stratospheric".
Hope I helped.

Re: HKS sedan exhaust
I put the HKS on my car earlier this month and love it. Yesterday, I dynoed my car and it yielded 7 additional HP at the rear wheels compared to my last dyno, which was only with the Stillen, Z-tube, and GroundingGear. I also perceived that the HKS restored the lost low end power after I put the Stillen on.
Regarding sound, it's very mild, only a little louder than stock, but a nicer deeper sound. It also actually balanced out the Stillen intake sound, so the overall sound is much more complete at WOT.
My next dyno will be after I get my TS F-Spec ECU (it's in transit right now), and I'll keep you posted.

Re: HKS sedan exhaust
I have the dual tip HKS rear section exhaust and like it lots!
Before I installed it, my Stillen HF AB and Z-tube combo
was really loud. The addition of the exhaust has seemed to
quiet down the intake. The sound is addictive. I am always
goosing the car to hear the beautifull music the intake/exhaust
make togeather. Love it! No droning. The idle sound is a little
deeper. Cruising on the highway is also very quite.
It only sounds mean on accelaration. See my Sedan pics
to see my HKS exhaust.

Re: HKS sedan exhaust
I'm liking the sound of this one. Does anyone have it in combo with a Y-pipe? That would be more comparative to the full systems like the Stillen or Borla.
I'd like to hear more about a Y-pipe + HKS review, in terms of gains, sound, and cost.
Additionally, where can the HKS be purchased?

Re: HKS sedan exhaust
mostly sound advantages. the sedan midpipe isn't that restrictive, it's straight through. if searching for performance, the midpipe should not be replaced. replace the y-pipe instead OR go with a full cat-back system

Re: HKS sedan exhaust
RacerX,
Mine is just the rear section exhaust, aka muffler.
I have been thinking about a Y-pipe upgrade.
I realize that the muffler alone makes only minimal
HP gains. HKS claims 10 hp. Probably not.
But with a Y-pipe upgrade, probably more.
