i got a question, i just recently picked up a hytech replica header. I have a omni style adjustable testpipe on my car right now. It is 3 piece adjustable, would this work, or do i have to get a new testpipe. My current test pipe is already 2.5 inches.

Thanks for any input, this will be going on an em1 with the b16.

 

the header deletes the cat so if your test pipe is wear your cat was then your gona have to get rid of the test pipe for it to work.

 

I know it gets rid of the cat/testpipe, but there is going to be a little gap between the header and b pipe, my question is, my omni testpipe is a 3 piece type that can be shortened, my question is have any of you guys out there used this header and testpipe setup and does it work without welding? or do i have to get a pipe welded between it?

 

How do you know theres going to be a gap?

 

I put the same headers on my em1 and i bought the extended pipe and just welded a flange to connect to the cat back. Your test pipe should work out for you no problems or welding.

 

your test pipe should work. I have the replica and a 4 way adjustable test pipe. and it fit with no problems.
