ISR Performance HGC Long Tube Headers Nissan 350Z Z33 / Infiniti G35 | IS-SSHD-VQ35

Took forever but such good quality

Packaging was perfect. not to much damage to the box. Seemed to come with everything that was listed. all in all- amazing headers so far and can’t wait to put them on my nissan 350z

Got these headers for my g37 and they fit perfect and still going strong 2+ years with no issues whatsoever. Delivery was fast and efficient.

If you’re looking for power in the low end and even more on the top end long tube headers is the way

Seriously. Best bang for your buck mod on these de z's. The long tubes bolted on with zero fitment issues. None at all. FITMENT WAS AMAZING. Will shift your power band to a higher rpm range, but you definitely feel the difference.

The rest of my exhaust is stock, but won't be forever. The tone is great, but I picked up a rattle from the oem mid pipe, not the long tubes fault.

Price for these is fantastic too. Can't find a better deal.

Seriously.

The product is very good, well worth the money I’m just experiencing a weird rattle noise coming from where the headers meet the Y pipe I mean it’s nothing to crazy but maybe isr should look into that but overall it’s been treating me well!

Excellent Service, Fast Shipping, Great Product Selection!!! I installed these ISR HEADERS on my 15' Q50, coupled with an ARK GRIP SYSTEM. SOUNDS GLORIOUS!!!

Fast & responsive, buy again

Fast shipping and great customer service. Fit my G37xs coupe pretty well

Headers made all the difference in my g35 it is extremely loud and it breaks everyone’s neck as I drive by definitely buy header wrap.
