I have a dc sport header and a buddy club exhaust and I am looking for a good test pipe preferably a 2.5 in inlet and outlet that will fit my setup. Can anyone recomend a good test pipe? Also do I need one with an o2 bung? I have swapped a b18b into the crx if that helps.

 

go custom with it, probably give you best results, doesnt cost much to have one made.thats just my opinion.

 

I went to a local muffler shop and asked for a 2 ft. peice of 2.5" pipe. They gave it to me for 10 bucks. Then I got some flanges from Napa, measured and cut everything to length, marked the clocking on the flanges, and gave it to my GF's Dad to weld it up.

If you want a really nice plug and play pipe that is adjustable, and is made to fit your 60 mm aftermarket exhaust, I reccomend getting an Omni-Power test pipe.

They run about $85-90 and are really good quality. http://www.kteller.com is where I reccomend you buy them from.

 

Will the JDM omnipower test pipe fit a DC sports header even though it is 2.5 in. Or do I have to get the US testpipe?

 

JDM = 2.5" collector.
USDM = 2.25" collector.

 

i know the collector size, but will the bigger jdm test pipe fit the dc header? because it seems that it will fit the 60 mm exhaust on the other end.

 

Yes it will fit, the omnipower has a 2.5 inlet but only 60mm(2.38") tubing at both ends. If you only plan on running 60mm exhaust then it will work. If you want 2.5" go custom. Kteller also sells custom pipes.

 

http://www.kteller.com

has all your custom test pipe needs.

 

I would go custom, but I don't know what the length of the test pipe needs to be. Also I only found 2.25 to 2.5 test pipes from kteller. I was looking for a 2.5 straight through
