ok guys I have these headers for my 2200 auto 1999. specifically I know i have to weld them on to my car. question is I bel;ive it is going to weld on to the stock flex pipe on my car. Do i have to change the flex pipe to another one or can i simmply just install them to my stock flex pipe on my stock exhaust. I have a (2.25'' borla exhaust cat bak). If not what do i have to do so I have no problems upon install. plan to get some motor mounts soon but not yet. thaks also how is the sound and perfomance upon install and what should I look for upon install upon putting on. In other words WHAT DID YOU DO!!!??????????????

first, our cars only have ONE header....not 2. if you bought 2, well then that just sucks. good luck


this is my sig

Get a 2.25" flex pipe from an exhuast shop or something
