question about test pipes
i just install a fast intentions cat-back on my Z. but im still deciding if i should put test pipes or not,
what brand do you guys recommend me?
u guys think they can be install by myself like i did with the f.i. exhaust or im better off taking it to a shop,?
and if i stall them would i get a check engine light , or do i need to do a dyno test. if you guys can guide me i will appreciated it thanks
