I have a 95 Integra GSR, i bought a dc sport header off my buddy and he has a 98 integra ls............will that still bolt up to my motor since it came off a ls?............and should i put the header on with the stock cat or buy a test pipe?......thank you

 

it will bolt to the head but may not line up with the rest of the exhaust

 

I'm pretty sure the collector is too long.
