I'm installing a JDM 4into1 header on my 2000 LS/Vtec powered integra. And I am using a stock type r b pipe and muffler. My question is how long does the test pipe have to be between the header collector and b pipe. I'm not using the cat this is for off road use. I want to be able to get the pipe made at the muffler shop so I don't have to drive the beast off the header. I'm sure some of you have had a pipe made and know exact length.
Thanks

 

hope you live close to the exhaust shop. no offense. **** we run open header at the track.

 

I do live simi close to the exhaust shop. But **** if I get rolled by the pigs it won't be pretty

 

they might understamd if you tell them that you are going to the exhaust shop.

 

maket it to the same length as your usdm cat. i think its 17"
