Okay, so I had planned to get Long Tube Ceramic headers. But I was told that it may be difficult to put on the headers if I wanted to keep the Cats on.
I do not plan to drag race this car or anything and still use it from time to time as my daily driver so I need to keep getting it inspected.

Is there a way that I can put on long tubes, keep the cats, and have some sort of O2 sensor extension?

Or will the normal one do?

Would it be better to get shorties???

They sell catted x pipes, bbk makes o2 extenders.

Oh really?

Thanks!

If you are worried about cats, you might as well just stick with shorties with a catted h or x-pipe since you don't plan on racing it or anything. I doubt you are going to be doing any other substantial mods to your daily (ie: h/c/i), so you will actually benefit more from the shorties if you are closer to stock form.

That was my biggest concern. I felt that I really didn't need the long tube since I mostly keep this car in the garage. Thanks for all the input!

One more question, Is there a huge difference in the equal length vs non equal lengthed headers?

not really, no. the headers on my car are unequal and the motor does just fine at 600rwhp

You could also get Tri Y's, which is what I run. A set of Doug's that run 1-5/8 primary stepped up to a 2" secondary that steps up to a 2.5" collector. They don't suffer for top end power(but not quite as much top end as LT's), but work well on a DD setup since they work better at low-mid rpm than LT's do. But of course their biggest advantage is fitment and ground clearance. Some companies also sell mid-length headers as well.

As far as equal vs unequal, for most of us it doesn't matter, but it can matter on some race cars. Equal will tune each cylinder for best power at the same rpm so the engine makes more peak, while unequals will tune each cylinder to make best power at different rpms spreading the power out over a wider rpm range but with less peak. Typically equal is better for drag cars or high speed circle track where the engine will be operating in a relatively narrow rpm range, while enequal is quite common on road race and rally cars that have to operate over a wider rpm range. On a street car though it won't matter, they're not subject to the same class restrictions that race cars are that make that extra couple hp matter.
