JHM Stainless Steel Downpipes are MADE TO ORDER products built by Fast Intentions. They should ship in 2 - 4 weeks from the time your order is placed. These Downpipes fit Sedans, Avants, and Cabriolets

Why did JHM decide to sell Fast Intentions Downpipes instead of making their own? Well after we went 12.97 @ 109.1mph in the quarter mile (fastest all motor time) with a car we tuned with a Fast Intentions cat back and downpipes we knew they built high quality products. We also wanted to have an option for those who didn't want to step up to JHM Longtube Headers but still wanted a little more performance potential than a piggie style downpipe.

Why 2.5" piping diameter? After much testing and calculations based on the 4.2L 40v V8 engine's demands it is the optimal size. With a 2.25" exhaust or smaller you leave yourself no room to grow with more mods. We have also found with a 2.5" downpipe torque is not sacrificed and the top end gains and the room for growth far outweigh going with a limiting 2.25" cat back.

Includes: Both 2.5" stainless steel downpipes with flanges, high quality flex couplers, mid pipes and all hardware necessary.

Options:
-Automatic or Manual Transmssions: Specify with the drop down box below your transmission
-With or Without Cats: You can have these downpipes made with 300-cell, high-flow, race cats. Select your choice from the dropdown box below.
-Cat Back Connection: If you have a full 2.5" cat back that is not necked down select the dual 2.5" connection. There is only a $25 charge to pay for our cost on the larger clamp. If you have a stock cat back or a necked down cat back then select necked down. NOTE: If you have a dual 2.5" cat back and it is necked down, it hurts perfromance. You should get the full 2.5" and then have a local muffler shop or fab shop modify the end of the cat back to be a full 2.5" so you don't restrict these downpipes.

NOTE: Like ALL aftermarket catalytic converters these downpipes are technically not legal in the state of California and other states (check your state laws for details). In California ONLY stock catalytic converters are technically smog legal. All others are not since the DO NOT have a CARB E.O. number.

NOTE: For the C5-allroad V8 you will need to choose AUTOMATIC Downpipes from the options below. Custom fitting will be required to fit your cat back (adapter needs to be made). Professional exhaust installation is highly recommended.
