ok i got a exhaust from my in-law he says it'll fit on my gsr (95) so not knowing much i tried and it didn't fit the pipe was too long and the piping didn't seem to be the right size either...so i talk to him about it he says i have to wield it on so...not know much about cars just wanted to see if it is a good idea..........the exhaust is a greddy evo i think not exactly sure....tips plz....his car was a 94 civic ex coupe

 

If it doesn't fit of course you are going to have to "make it fit". I recommend not doing so unless you are making enough power to have that airflow, or if you never want to upgrade to need a better exhaust.
