Why did JHM decide to offer "piggie" downpipes? First and foremost these modified OEM downpipes have been tried and true for the B5 S4 since the early 2000s before anyone made an aftermarket downpipe option. They were and still are a great low cost power upgrade for the B5 S4. Since we have dealt with them for years in the older B5 S4 we wanted to bring this simple yet effective downpipe to the B6-B7 S4 platform. For the past 2 years now they are a JHM proven modification for the B6-B7 S4.

Performance:
JHM went a step further and set out to prove the "piggie" downpipes performed. So we too a car to the dragstrip and we went 13.03 @ 106mph in the quarter mile (fastest all motor time) with a car that only had "piggie" downpipes we did in house, JHM tuning, FI catback, JHM intake spacers, JHM Clutch, JHM Lightweight flywheel and JHM Lightweight rotors. "Piggie" downpipes are also a great option for the mild bolt on S4 who don't plan on major upgrades down the road and want a stock looking downpipe.

Sound:
Another great benefit to the "piggie" pipe over stock is the slightly more aggressive sounding exhaust note. So if you have an S4 with an aftermarket cat back exhaust already and it is a little too quiet with your stock downpipes then these are a great way to help get that true V8 sound out of your existing cat back.

Includes: Both OEM modified "piggie" downpipes with OEM main cats and relocated rear O2 sensor bungs. NOTE: The rear 02 sensors need to be relocated behind the main cats, the stock rear O2 wires are long enough if done properly. See a pic of where they go -->HERE.

Options:
-Automatic or Manual Transmssions: Specify with the drop down box below your transmission
-With or Without Cats: With Cats the stock main cats remain (same configuration as our car that went 13.03. ) Or we can fully remove all of the catalytic converters for a catless downpipe which will allow more performance above 5000rpm. There is an additional charge to remove the main cats as well. Also with NO cats you will get a check engine light for the catalytic converter efficiency, this will not affect performance but will turn on the check engine light.
-Core charge: If you can't afford to have your car apart long enough to send your downpipes to us for modification we do offer them already complete. You just pay a core charge, we send you a set then when you ship yours back to us we credit you back the core charge. (NOTE about cores: You may receive a pair of main cats with different mileage than the ones on your car if you opt for the core option. Example, if your car has only 30k miles an you buy them from us with a core charge then we could be sending you downpipes with 15k, 20k, the same, 50k or 75k+ miles.)

NOTE: Since the pre cats are removed as part of the modification technically these downpipes are not legal in the state of California and some other states (check your state laws for details). In California ONLY stock catalytic converters are technically smog legal, you can't remove any of them. However JHM has found that the emissions out the pipe do pass the California emissions test and the pipes do pass the visual. If you opt to have all the cats removed the emissions will be too high out the pipe. Obviously JHM still sells these as an "off road" use only downpipe.

Video notes and info. The 2 videos above can hopefully help you decide if the "piggie" downpipe is the right sound for you with examples of them coupled with 2 different exhausts.
