Greetings,

I heard in the forum that the Old HKS dragger Cat back are
restrictive and can make your car loose some boost.

I have a HKS super dragger on my 95 FD and I am wondering
if I should switch for the new version. As far I can see, there are
2 holes in my cat back when I look inside. One big hole in the bottom
and another small one in the upper.

Any advices?

Thanks all
Serge
