I must say these fit amazingly, and sound great! My old convertors were leaking and clogged. I noticed an immediate change in exhaust sound, and performance. However, once it left Concept Z the shipping company (Fedex) dropped the ball BIG time, but I can't hold these guys accountable, as it was out of their hands by then. All in all GREAT product, and if i had or acquire another g35 or 350z in the future. Will be ordering another set!!!

good for the price tbh not going to lie

Very satisfied with the down pipes, got em in 2 days!

I have cel light for 02 sensors after installing. Also didn’t come with 2 oxygen sensors plugs on the test pipes. Only one hole for oem sensors. 7/10 you get what you pay for

Heres a honest review havent gotten the product yet but so far shipped really quickly just have to wait for it to arrive now and i will get back to you guys shipped over night
