exhaust length for gsr swap

[lohonda]

My friend is putting a gsr swap into his 94 civic dx coupe and he was wondering what length the cat has to be for the header to bolt up. I remember reading somewhere what the exact length was, and that some company made a high flow cat that was the same length and would bolt right up. He would rather buy a high flow cat that bolts right up instead of having a shop weld up an extention.

Thanks

just get a high flow cat for a GSR header, and bolt up your exhaust, or since your car is obd1 and I am assuming you live in florida, you could consider a testpipe, but a lot of members won't agree with me on that one.

if obd2 engine, you might want to rock an oem teg cat to stray from possible funny idle and runn'n a little rich
