i'm kinda new to all modding cars
and i was thinking of changing the exhaust to begin with

i'm thinking of getting a cat back

and my question is that when u get new exhaust, is there need of change all the pipe things...

when i look at many of treads, people get new down pipe when they get new exhaust, and i really got confused

or can i just change the cat back...
help me answring my questions plz

thank you...

 

you can just change the cat-back. that's all i did so far - i will free up the exhaust later, when more funds are available, with a downpipe and hi-flow cat; but i am happy for now.
