Less than a year old. CARB approved with sticker. Bolt on 12 to 18 HP and torque gain. These headers have had the internal weld burrs removed for better flow and I have installed bolts on the downpipe flange similar to the stock manifolds. $750 shipped in U.S. Pictures on request. - C.
I’ve heard that stock cats flow almost as well as high flow cats so, unless you have a lot of mods, I don’t think that will be a factor. What will be a possible problem is location, if you are thinking of LT’s. Depending on the brand, you might face a bit of cutting and welding in retaining the...
Edit - WOW! These things are absolutely amazing to me. Wonder If I could organize a straight shot across Alligator Alley?
Build it and they will come....

Tuna,
Sorry I didn't see this sooner. I'm kind of new this forum. Welcome to Open Road Racing, Texas style. That was a nice write up of the event. Glad you had such a good time. It was my 6th Big Bend, third time in the 145 class. My wife ran in 140. Got to warn you; this stuff gets addicting...
I went from 99 Z51 sways and shocks to 04 Z06 sways and Bilstein Sports and got a noticable improvement in cornering and a firmer, controlled ride. I changed the links to steel after I saw how twisted the plastic ones were. I'm not sure how big your swaybars are but you should also consider new...
A set of pre made MSD wires for a C5 costs about $60 from Summit Racing. They are a bit larger and spiral wound for less resistance and are also a bit more heat resistant than stock. You didn’t mention plugs but the stock Delco’s have a reputation for loosing the platinum puck, so you might want...
In order to use the 2001+ exhaust manifolds on your 99, you will have to change the air tube on the passenger side and replace the H pipe assembly with a 2001+ as well. Those manifolds are about two inches shorter than yours. – C.
Anything would be better than your stock manifolds, even the 01 and up version. However, you have to think of a change to headers as part of an overall plan depending on what other mods you will be doing and how you will be driving. Putting a set of 1 7/8 LT's with high flow cats and open...
Ceramic Coated B&B Headers for a 2000
These will only fit a 2000 C5 with cast iron manifolds. They have not been used since they were coated by Jet Hot. The passenger side has some minor cosmetic rub marks due to installation. $500.
