I'd like my car to breath a little better and was wondering if anyone has took off their stock headers and replaced them with Z06 headers? I did a search but couldn't find anything and figured someone has to of done this.

I would be replacing the headers and cats. I was curious if you had to get the car tuned by a pro afterwards to avoid error messages or will the car make the adjustment of a less restrictive cat converter?

What year is your car? IIRC all exhaust manifolds after a certain year are the same as the Z06...?

Sometimes a tune is required, others it isn't. To get it to breath the best and get the most performance out of the swap it is a good idea to have it tuned.

If you have a LS1 97-2000,, installing a ZO6 style exhaust manifolds will net you a few more HP. Nothing to write home about. When you change engine exhaust manifolds, you will most likely have to install a matching year (style mid-pipe) only because the manifold outlet angle and length will be a little different that your OEM manifolds.

NO,, You will NOT need a tune!

They really are not HEADERS. They are manifolds.

On another note, you could install a set of C6 ZO6 exhaust manifolds and mid-pipe on your C5 which would add a good bit of HP.

If I didn't want headers and wanted more power,,, That's what I would do!

With the amount of work, money and parts involved in that swap your much better off just doing a set of inexpensive long tubes (texas speed, OBX etc) and pick up 25-30 HP the right way. Do it once the correct way and save yourself the headache and wasted $$ later.

In Calif you can not have LT's

Oh didnt notice his location,,,,,Yuck! In that case the C6Z manifolds are the best bet for adding power.
Man CA is tough for us car guys and gals huh?

I have an 04 and the Z06 exhaust would be from an 04 also

Thanks Bill

I'll be doing the work myself so won't cost much.

Then you'd be swapping the same parts back on. The only Z06 exhaust parts worth using are C6Z06, and only then if you can't use headers.

I did this swap on my 00 convertible and with a tune...I picked up lots of power...really opened up the car...you will have to have someone weld on a flange end for the c5 exhaust system ...however

My 2 cents, hardly worth the time and monies. Stay as is or install headers
