ZZPerformance 3" Off Road Stainless Polished Downpipe Description The Very Best 3800 Series II Downpipe In the Market
Now includes o2 bung.
We are the leader in the 3800 Series II engine and have been making and selling these downpipes longer than anyone on the market. The stock downpipe is very restrictive. Depending on what you have done to your car it adds up to 15 HP.
This is a complete bolt on. Will bolt to your stock exhaust manifold and connect to your stock catback exhaust system. You'll see others trying to replicate, but there is just no comparison. We run Interlock Flex Section. Not a cheap flex that frays away. All the flanges and exhaust hanger is also stainless.
Front and Rear Gasket is also included.
Keep in mind this is a Performance off road pipe. No catalytic converter. This will free up horsepower, but will throw your check engine light on if you do not have an o2 emulator or PCM programming done. We will have another sale up with the same downpipe with a catalytic converter.
This fits on all the following cars:
1997-2008 Pontiac Grand Prix with 3800 Series II engine-Both Supercharged and Non-Supercharged cars2000-05 Monte Carlo 3800 3.8L Engine Only2000-05 Impala 3800 3.8L Engine Only1997-03 Regal3800 3.8L Engine Onlyand 1998-99 Intrigue3800 3.8L Engine OnlyAdd $20 for UPS ground shipping within the U.S.'s 48 states and Canadian buyers $35 for UPS Standard.

Which makes it cheaper and faster to get than shipping by USPS.
