HKS Dual Hi-Power Cat Back Exhaust

G Fo12ce · 05-30-2015, 11:56 AM

***SOLD***

Selling my exhaust, I've put back on the factory exhaust as I plan to sell the car in the near future. At this time I would prefer to sell it locally in Southern CA. My car is my daily driver and never had more than intake and exhaust so the system has lived a pretty mild life.

Highlights:
-HKS Dual Hi-Power P/N 3209-BN004 stainless 60mm piping, 120mm Ti burnt tips. Tips are from G37 Kit BN003 (read the story) meets the legal CA sound level testing (95DB)
-It has a small scratch at the edge of one of the tips, but it's on the bottom and not visible when installed.
-The cross brace (center section) was modified at HKS USA. (read the story)
-The rear sections/muffler sections feature the newest design from HKS and have the longer G37 tips, still adjustable length as well (read the story).
-The sound is nothing short of sweet and still as consistent as day one, they are designed this way.
-I did a quick cleaning and you can see it's still in good condition.
-Includes all the hardware and gaskets.
-SOLD

Story:
Here's the free story that comes with the exhaust

I had friends at HKS USA (when it was still open). In 2011 HKS redesigned the Helmholtz resonators on the rear section of the 370Z/G37 exhaust. These resonators are the cool looking ones that are plumed in right before the muffler. So, the muffler sections are the newest design! This new production set was sent over from Japan for dyno and sound testing (done on my car). In order to make a complete system they used a new Y pipe and mid section they had in stock. The resonated mid section was from the first batch which was withheld from sale because HKS Japan in a rare error welded the cross brace on it upside down. Its a thick/wide bracket, so Howard their Head Engineer ground it out to make it look like it should and clear the drive shaft. I never had an issue at stock or lowered height. Another great thing is since I got to have it assembled at HKS they allowed me to choose the tips. Of course these are the burnt titanium tips but the 370Z kit (3209-BN004) and G37 kit (3209-BN003) used different lengths of the same tip. Since I have a NISMO I chose the slightly longer G37 tips to meet the edge of the diffuser. The tips are adjustable in length also. If you have a body kit, a NISMO or just want the option of more outward adjustability later this is an awesome option you would not otherwise have. Another fun fact is they discovered while putting it on my car is the NISMO has a extra hanger bracket on the driver side that has to be removed so they took pics of this system on my car to make the supplemental instructions. If you have a NISMO I can provide those.

Let me know if you have any questions.

I changed the contrast on the below pics so the etched part #'s would show better, that's why they look weird:

A few more pics from when it was installed at HKS USA (R.I.P.)

. These are when it was new as and you would expect now the more forward you go the pipes are a bronze color now from heat cycling. If you want to spend an afternoon you could polish it more than I did, I think it looks cool now:

I took a deposit from Trips until Sat. He deserves it for all the hard work he does on here. I'll report back then to update this on whether it's still available or not.

I have this exhaust on my Z and it is fantastic! Nothing but compliments from on-lookers. GLWS
