I'd like to replace my cat with a test pipe. I have an oem header and exhaust and would like to add a test pipe for the sound factor. What size is recommended? Is there a test pipe that fits both the oem header and oem exhaust? Thanks For any help in advance.

63mm but ppl like 70mm

Size of test pipe depends if you plan on changing the exhaust.

Thanks, but this tread doesn't really answer my question. Are you saying that 63mm is what mates to the oem header and oem exhaust?

I have no plans to change the exhaust. I just want a test pipe that will mate with my oem header and oem exhaust.

Yes
Did you really read that thread or browsed through it? Good luck Justin

OP said he has stock exhaust

All test pipes for the s2000 will mount up to the stock exhaust regardless if it's 60mm, 63mm, 70mm, ect.. If your planning on keeping the stock exhaust get a 60mm one since that's the size of the OEM exhaust. I had a 60mm Invidia test pipe with CEL fix on my S and loved it.

^ Its all good. I got what I need here. I haven't decided, but I'll likely go with the 60mm.
