The ZZP 3800 Equalizer Downpipe is the solution to perfecting your 3800 build. We all know how potent the 3800 platform can be, however there's always been one thing that has held them back; sound. Even with a great exhaust combo it's been nearly impossible to get FWD 3800's to sound good due to the crossover pipe causing unequal exhaust pulses resulting in rasp. After multiple revisions, many prototypes and miles on the concept we've come up with the perfect solution to make that 3800 sing. This product essentially changes the stock unequal length setup to an equal length exhaust. 

Our equalizer setup includes our unique crossover tube, rear manifold block off plate, and the primary downpipe. This setup requires a TOG style downpipe which can be found here: TOG downpipe. The TOG downpipe will connect between our primary downpipe and your catback. Fits stock front and rear manifolds and ZZP power logs; does not fit cars running stainless header package. You will likely want to add a 3" 2 bolt gasket, found here

Includes: 

  • Equalizer Crossover
  • Primary downpipe
  • 2.5" v-band clamp
  • Rear manifold block off plate
  • O2 bung plug
  • Hardware necessary for installation


Check out the videos below for sound clips. While these clips do a good job of catching the tone difference, it's hard to truly capture how much better this setup sounds over a "standard" exhaust. We know you're going to fall in love all over again with your 3800 car as soon as you get this installed. 

Although a resonator is now not as essential with the equalizer, it is still recommended for reducing drone.

Equal length exhuast

Completely transformed the sound of my Monte Carlo I also feel a power gain from it . Also running a XP cam and E-85 with a 2.8 supercharger pulley. Made my car so much more fun to drive and hear and feel the power from this exhuast system! Thank you again Zzp For providing awesome modifications for the W-body platform as it is getting bigger and bigger by the day!

Really modernized the cars sound!

Really transforms the sound of the 3800. Bolting it up wasn’t very fun but once you get it lined up right you’ll love it.
