Question: I have a 95 z, a4 car with mods shown below. best time is a 13.81 at 99.35 as it sits. I live in a rural county of northern california which doesn't have emission testing. I was wondering if it would be worth the trouble to go with an ORY while using the stock manifolds. As everybody probably knows how much fun a header install is on these cars I don't need to defend my lack of desire to change manifolds. I was wondering if these fit onto the stock manifold flanges (with welding I'm sure) and are the tubes 3" from there all the way back to where it ends? will this yleld any more power (I'm sure I have to tune the PCM for this) or is this just a waste without the long tubes that I already know will make more power than stock manifolds.THANKS!

 

seriously, go for the long tube headers.

I've made several posts explaining what to do with pacesetters and a 95Z. They drop in from the top. Search my posts and you'll find it as i posted several times

 

I agree with Torque, don't mess with an Offroad Y-pipe while retaining the stock manifolds, it's not going to buy you much. Save up your money and make some time and invest in a set of longtubes.
