Ok so i have to change out my oil pan due to the fact that the guy i bought it from striped out the drain bolt and it all leaked out a week after i got it home. I only paied 1k for it so i wasn't to angry. When changing out the oil pan i have to remove the downpipe as everyone knows so i was thinking about getting a better exhaust setup.

Here is my question, will a JDM ITR header fit on my 1990 integra ls? I think the mid pipe wont bolt up to the downpipe, but how will the rest of it fit with the radiator and ac and what not? Has anyone tried this or has this setup? I searched but came up with nothing.

Thanks for any info that can be given,
Nick.

 

i think it should fit in the engine bay but collectors bigger and might come up short on the exhaust

 

same length but collector is different as stated above.
