Test Pipe

[HotAirWH1]

Does anyone know or have experience if the Kirban Performance Products Test Pipe 4 bolt flange will marry-up to the Magnaflow "Y" pipe (4 bolt flange) for the GN. Neither manufactures of the pipe have any specifications on their flange size / bolt size & location dimensions.

Jason at RJC will have all relevant data for his.

Short answer, yes they will marry up.
The 4-bolt flange is whats on the stock exhaust. For a test pipe to mate to the stock exhaust and for a cat back exhaust system to mate to the stock cat (California living) they have to the same.

We stock test and dump pipes which will fit a 3" downpipe, and mates to the 4 bolt exhaust pipe.
