This is HKS’s newest exhaust for the 350Z. It is part of the Hi-Power line. This version is a full dual Hi-Power Ti (Ti for titanium tips). I will explain how this relates to the G35 Coupe in a second. The system includes the “Y” pipe, but in this system it is more of an “H” pipe because each bank is kept independent in “true dual” fashion but are joined by a balance tube. I guess it still looks like a Y but whatever, you’ll understand when you see my pictures. The H pipe has flex pipes and resonators. After the H you get the dual intermediate pipe and the two rear sections. As you will see in the pictures it is full SUS304 stainless steel front to back with the exception of the titanium tips which have that cool looking heat discoloration. The piping is all mandrel bent and is 60mm (2.36”) diameter. The muffler diameter is 130mm (5.11”) and the tip diameter is 120mm (4.72”). Because it is full stainless it is under HKS’s 4 year warranty program. A key feature of this system is that it complies with the California vehicle code and is compliant with the 95DB sound pressure level limit. So if you get cited you can have it certified at one of those referee stations to be street legal. Another cool feature on the tips is that they designed them to be adjustable. They will fit flush on the stock bumper but can be adjusted out to match with a body kit that may extend the rear bumper! That’s why the tips have those bolts on them.

The most unique feature of course are those tuned resonators that are plumbed in before the mufflers. They made it possible to have a true dual system while passing the afore mentioned 95DB limit. They were also specifically designed to reduce the drone and rasp the VQ35 has between 2000 to 3000 RPM and I think they look cool. It just looks like something cool is going on there. For those of you who may not like that look, not to worry, as you will see on the pictures they tuck under the car and you can’t see them but I’m sure you will still appreciate their functionality. Ok, here is the sweetest part, average HP gains in testing with no other mods was 12 at the wheels. I think most of you experienced guys know that HKS doesn’t mess around and they are well respected. They aren’t known for inflating #’s, in fact as I stated on my Legamax exhaust post they usually report an average to be on the safe side, as to not disappoint customers. They haven’t been around for over 30 years for nothing. Price has yet to be released and ETA is around end of June for the 350Z. A friend of mine there says if the initial sales go well then they will make a version with a longer intermediate pipe and specific for the G35 Coupe.
If any of you guys are like me and are already drooling make sure to give the HKS sales department a call, ask some questions and let them know you would be interested in purchasing one should they decided to make it. (310) 491-3300!

I was told MSRP price isn't finalized yet but it's going to be around $2,000 retail. I was told it was going to be priced cheaper on the retail than the Japan market version even though ours will include those silencer/resonator chambers and thiers will not, so that's good news. But so far it is in production for the Z only, like I mentioned earlier. If you think you might want one later one your G you should call the HKS sales department. I think they are trying to play it safe and see if the Z guys resond well to a high end upper end priced system before they decide to make it for the G. If we start calling them with requests or questions then I think it'll speed up the process. I know a lot of you guys appreciate the quality and would buy it, it's just a matter of convicnig them it's a no brainer. Anyway I'm glad you guys appreciate the post, I'll keep the info comming on as many products as I can.

anyways you can get that one and fit it on the g. When i was looking to get an exhast. The guy selling it to me was like you know you have to get an extender piece for it. Its not that hard. Any exhaust shop can do it. I called HKS and they said it was around 1500 for the exhaust. So i went ahead and put in an order. I think its the best looking one so far. As for performance he said they got a 8 hp gain. Thats pretty good. Just have to hear how it sounds now.

Gabe35Coupe - Great Post! Thanks. I would buy it in a heart beat if they made it for the coupe, without having to get the extenders.

If/when they decide to do it for the G it will be specific (no mods necessary). I believe all they would have to do is make a longer intermediate pipe and maybe extend the tips a bit. But since this system has adjustable tips they might be able to leave the rear sections alone! Anyway thanks for kind words about my post, much appreciated. I will be doing more soon like the one's I've done in the past. I believe you can search by poster if you want to see my wheel (LE37T) and HKS Legamax exhaust posts. I will be keeping a friend at HKS up to date on your guys' reaction to the system so hopefully getting one that you won't have to modify (from the Z version) will be a reality soon. I feel you, I want one too!
