HKS Hi-Power Dual Axle-Back Exhaust - Infiniti G35 / G37 / Q40 Sedan
Bought this as a gift, install was a breeze. Didnt make the car loud but added a nice deep tone and they look amazing. Quality product.
This is something that is for people that don’t know anything about cars. It does not sound that much different than the stock one. It doesn’t give you any performance what so ever. Infact it makes the car have less horse power. It’s also not a cat back that would be accompanied by a downpipe and headers. I bought a HKS for my RX8 a few years ago and it was sweet. But this was embarrassing to say the least. I won’t ever buy another one by this company and I’m not doing extra work so until I buy the new one I won’t be changing it back to stock then changing it again. So I’m stuck with it. I have to now find a real cat back. One that doesn’t just bolt to the stock pipes for a little more noise. Company is nit what they use to be. It looks bad being 4 inch tips. Does not look tough just FyI
Happy with the purchase price, and quality of my product. Only down side was slow shipping time with little updates. Took 2 weeks to process order but once shipped received in a couple days.
The best Axel back
The exhaust fits just perfect! Sounds a lot better than the stock one.
Worth it and it was fast
Faster shipping I ever seen
Fastest shipping ever
Literally the fastest shipped thing i ever got looks great easy af to install sounds great has a deep tone just a litter louder than stock but not annoying makes a big difference
I'd like to start off by saying that the faculty were great about answer the question, if it would fit an G37x AWD Sedan? The product was delivered within 3 business days with standard shipping. The Exhaust was relatively easy to install for someone like myself with no experience at all and the quality is great. The exhaust enhances the sound of VQ engine without being too loud.

Product was great easy enough install great look overall happy with it clean smooth sound
Best Exhaust Out
quickly and efficiently
Easy install “plug and play”
KamiSpeed immediately contacted me when they ran out and provided me with detailed shipping.
Installation was a breeze, fitment and quality are amazing. Exhaust definitely sounds deeper and louder with the rest of my stock setup, but quiet enough for cruising. I'd recommend it. Chose this over the tanabe axle-back.
Fast shipping and great packaging. Literally, Amazon speed in terms of delivery.
Will this fit an AWD? Heard it’s only for the RWD models
Yes, it will fit an AWD as long as its a sedan. The only difference between the 2 is Y pipe. So this axleback will work.
Will this fit a 04 G35 sedan?
It wont work on the 2004 G35 Sedan.
Will this fit on a 2008 Altima coupe 3.5?
We have no data that this would fit the Altima. It may bolt-up, but may not clear the rear bumper.
