I was talking to a buddy of mine who helped build a Nissan 350z that is insane... anyway, after talking to him about my car and exhausts he thought that i should just get a custom exhaust built... he said its a lot cheaper and will probably perform better than any exhaust out... dont know if that helps you at all but just giving some input since i was also thinking about buying a greddy... if anyone wants to see that car he built message me this guy knows his stuff
Custom exhausts usually sound like shit, usually don't perform any where near as good as TOP brand parts as they have not been tested.
When you purchase a Greddy or HKS product you are getting proven tested products. When you purchase some shit brand or your local grease monkey exhaust set up you are getting normal steel with shitty welds. You get crush bends where ever it is required instead of Mandrel bending with flow and testing to back it up the flow WILL be restricted.
When you buy real product you get Stainless steel, Mandrel bends, a warranty, and proven gains as long as you don't buy shit.
Maybe its because my cars are worth over 40,000 each but I would never buy junk for my car.
What is done to the Z?
