im looking to buy a tbe from buschur racing , do i need to get a new donut gasket for the downpipe? and what o2 housing will work with the buschur downpipe?

 

their downpipe doesn't use a doughnut gasket and it should include everything you need buying it from BR. any 02 housing should work, dave prefers the ebay ones, you can get em for around $70.

 

thanks man , just making sure

 

They wouldn't sell you an exhaust without everything you need. The stock o2 and the Ebay o2s fit it, but not the Works or any other 3" o2 housing. The ebay type o2 is best anyway...

 

Why doesnt the 3in 02s fit, arent the flanges the same. And i thought the "3in" were made actually 2.9in so they would fit a 3in exhaust?

 

Because the flange on the BR DP has a 2.5" opening that mates perfectly to the stock o2 and Ebay o2, which both have 2.5" outlets. The rest of the DP (and TBE) is 3" piping, but that initial flange is made to mate to the 2.5" outlet of the stock o2 housing. It does not use the donut gasket as mentioned above.

It doesn't matter anyway - there is no need to get the $400+ 3" o2 housing that makes less power.
