i got test pipes YO!
don’t bother buying one, its a straight piece of 3 inch pipe. any muffler shop can do that for CHEAP!!
and the catback, same thing, any good muffler shop can make you an exhuast with whatever mufflers you want, and help make it sound the way you want. and if you have a problem or want to change the way it sounds, you can go back and have them modify it. I would recomend a twister inline muffler, with whatever you like at the rear. remember, that the larger the piping and mufflers and tip, the louder it will be, so don’t go over kill!! 3" is more than enough for your HP plans, and you don’t need a 5" tip!! look around and find a good shop that does nice welds, stand behind there work, and maybe one that does mandrel bends. you can probably do from the elbow back for alot cheaper than any pre-made catback system. my car came with a catback, and I bought a elbow, and then had a muffler shop do from the elbow to the catback, it was cheap and they did a great job, and it sounds SWEET!!
