Exhaust system question.

i thought catback exhaust is a pipe from the cat out to the muffler. ive seen exhaust systems that have more and longer pipes than what i've imagined.

heres an example of an exhaust system with more pipes

You're right about the catback-- from the cat, then back to the muffler. They may be generic pictures, I'm not sure. The exhaust can be much more straight. Mine certainly is ;)

You can also see the exhaust constrict at a point, which is bad (first link).

hey i need some help here i just got my 96 Eclipse an i was just wanted help finding a exhaust muffler i like the muffler that have lots of rip to it i have a ractive on there but its a fireball muffler an man it does not sound good help please

You didn't get a cat back in the description it says "Rear Section Bolt on Exhaust,Muffler,Mufflers,N1,95-99" that means its only the section after the second resonator. In the first picture it's the section with muffler tip. Thats probably why it was so cheap sorry to say you need some more piping for a cat-back system. The GSX exhaust is much straighter than the gs-t exhaust.

but can you put a GSX exhaust on a GST?

nope
