$949.99 Sale price

Model
Downpipe Option
Regular price $949.99
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 
  • Available with or without downpipe (catless or cat'd)
  • 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:

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

04+ Grand Prix's beware

If you have an 04+ Grand Prix plan on buying a couple extra transmission filler tubes, because the stock one will NOT go back in as is. You have to basically shape it into a pretzel, and hope you get the right angles. This header kit should come with a pre-bent transmission filler tube, ot at least a warning that you need to make a pretzel out of one to get it to work. As far as the quality..I'm sure it's good, but I don't know because I can't get the transmission tube back in...Almost a week now.

Awesome

Install was on a 2002 GS with a new beefed up long block with new 1.9 roller rockers and lifters from Summit Racing. Initially ran a full front and rear Plogs with 3in DP and thought that would be enough but after a while decided to go with this full header setup. Night and day difference starting mid range. Has a slight drone sound that only I can hear but nowhere near a deal breaker. Install was time consuming about the same amount to install the motor but time is irrelevant when it's the outcome that matters. You'll love the new crisp exhaust tone. Dynoed at 289 at the wheels before install ...this might get me over 300 and well into the 13's
