Im going to be running Dynatech long tubes and have no idea which length o2 sensor extensions to order. Can anyone clue me in? Thanx

 

I believe we got the 24inch ones from Thunder racing to do my little brothers longtubes. They are a little bit long, but I didn't want for them to be even remotly tight (which could rip them under load).

 

With my FLP's (same header design as Dynatech) I only needed 1 extension for the passenger side. Originally I spliced the O2 sensor and added 1 ft. and that was long enough, but recently I bought an extension and went with 2 ft. because that's all Summit carried.
