does anyone know how the TSUDO N1 JDM CAT-BACK EXHAUST SYSTEM is for the 08 scion tc?
i don't really understand what you mean good and bad. its an exhaust system, and it will help increase hp and whp. it's pretty easy to install, and it's a direct bolt on. i personally don't like the sound because it sounds a bit ricey to me, but thats just my own personal opinion. hks doesn't have a catback for the tc, but they do have an axleback available. for some reason, the price for the hks exhausts keeps on increasing. last year it was a couple hundred cheaper. check out the link i sent you, it has a pretty big comprehensive list of what online stores sell tc parts.
catbacks do nothing except make noise we do not need.
