ZZP Stainless Header Package

Exhaust - ZZP Stainless Header Package
Exhaust - ZZP Stainless Header Package
Simply put, these are the best headers money can buy for the 3800 platform. Perfect fitment, 100% stainless steel, simple installation, complete. These are a must have for anyone with a goal of 300+whp! 1 3/4" primaries, 3" VBand exit, and a matching downpipe.
  • No issues with spark plug boots touching headers 
  • No issues with primaries sticking out past flanges and preventing seal 
  • No issues with warped flanges because we had them done on a water jet 
  • Only 1 front to rear connection uses stepped band clamp. No more alignment issues or leaking donuts, quickest install of any available headers.
  • 100% stainless to last a lifetime, will never rust
  • Easy access to O2 sensor 
  • Cleaner install look due to no flanges on the crossover pipe, and no bolts to break or rust
  • No ticking noise common with some brands of headers

These headers will require a ZZP specific header downpipe which is included, just make sure to select the appropriate one for your vehicle. Downpipes that are designed to bolt up to the OEM style rear exhaust manifold will not work.

If you run into a fan clearance issue, you could either trim the fan heat shroud or you could switch the fan blade/motor assembly from right to left.

Not recommended for '97 GTs with the 460 transmission because of tight clearances. We dont recommend headers for an NA setup, we would recommend our front and rear Powerlogs for an NA setup. 

ZZPerformance will give a $50 coupon code for returning your stock downpipe to ZZP for catalytic converter recycling. Please email Henry@ZZPerformance.com a picture of your stock OEM cat and he will email you a prepaid return label. Then put your old downpipe (or just the cat) in the package that the new one comes in and drop it off at any UPS shipper. We'll email you a coupon code good for $50 off of your next ZZP purchase! Returned units can be cut up but the OEM converter must be intact. Already bought our downpipe? We'll still offer the $50 coupon code but you'll have to pay for the return shipping.

To take advantage send to:

ZZPerformance
Attn: CAT coupon
2450 28th Street SW
Wyoming MI 49519

For everyone: Include your original order # and email address to send the coupon code. Write down your return tracking number for your records!

Our downpipes come with a high flow catalytic converter that is 48 state legal. Our catalytic converters will not pass California or New York state emissions. Please contact customerservice@zzperformance.com if you have any questions.

Excellent Quality and Durrability

Installed these with a cat-less downpipe on my 02 GTP a while ago and noticed a huge difference over the past 10,000km. The exhaust note changed for the better and noticed a nice increase in throttle response, torque and fuel economy on the highway. The quality of the headers and downpipe is excellent, haven't had any long term problems at all with craftsmanship or warping and leaking even running them out and about in -30 degree weather. Install was rather simple with the rad fans out and the frame unbolted and lowered in the rear. The transmission fill tube needed to be modified for clearance and didn't go all the way back in but I haven't noticed any sweats or seeps around it over the time driving it. I would recommend spark plug socks to help prevent your spark plug wires from melting to the headers as well as some heat wrap around the harness to the rad fans as I did manage to melt it once. The only disappointment I have had with these has been the little zzp logo tacked onto the front bank fell off rather early on, other than that these have been a fantastic upgrade and are way worth doing.

The best headers but still not perfect

I installed this header set 11months ago on my 03 GTP. The quality of materials & welds are top notch. They even were nice enough to add an extra O2 **** for me :) in the downpipe section. These headers for like a glove with no clearance issues (except one I'll go over in a minute). I even have the shorter torque strut mounts & stock fans. Plenty of room upfront. The only 1 major let down. The trans dipstick tube. I'm not the only person that has ran into this issue. The crossover section occupies the same spot where the dipstick is supposed to go. I had to bend/twist/kink the **** of of it to make in go around. If it weren't for that I'd give it 5stars. These headers are a work of art and have 0 problems everywhere else. I did have my headers send out and professionally coated inside/out before installing.
