I think thats BS, I use megan racing o2 and dp and it fit exactly the same on my XS manifold as it did on my stock one.slideways wrote:if u are using sr 02 dump then u have to use sr downpipe and sr downpipe hits s13 rails when used on ca18. SO
use ca 02 dump and ca downpipe.
jsut buy the ssautochrome kit comes with manifold, 02 dump and downpipe for 125.00+ shipping. and if u dont want to use the manifold and such then sell it. but the dp works perfect on stock ca manifold and 02 dump.
and a work from the guys at ssauto,
out dump pipes wewre designed by xs power to be used TOGETHER which is why we sell it as a kit and not seperate in most occasions. ca18 ss manifold is to be used with ss 02 dump.
