JDM B20B in a 96 EK hatch, I have a Bisimoto header and running an Invidia exhaust. I have been trying to either make my own test pipe or modify the existing test pipe to fit to the header however im noticing that the header sits maybe 1/2 inch higher than the rest of the exhaust. What's the go to for connecting these pieces, all of the pipes ive tried sit crooked plus i have no bracket or flex by the header. Looking for either a pipe with a bend to weld to the header and bolt to the 3 bolt flange on the mid pipe preferably but open to any ideas

 

You will have to fabricate the proper "Test Pipe"... and it is a good idea to find a piece of mandrel bent tubing to use so that you can create the "Jog" that is needed to keep it in alignment and not "sit crooked". Welding a bracket to the header might help... or you can integrate a piece of flex pipe into your "Test Pipe". A source for exhaust pipe should be able to help... like K-Teller.

If all this becomes too much trouble, I suggest you pick up a better header... there are PLENTY of them out there.
