Porsche 911 996 Carrera C2 C4 GT3 1999-2004 Muffler Bypass Pipes
Up for sale is a pair of muffler bypass pipes that fit 1999 to 2004 3.4L and 3.6L normally aspirated Porsche 911 996 Carrera C2 C4 vehicles. I ran these on my Arizona based 1999 996 on the street for about two years. Nice T304 stainless steel pipes with polished tips with rolled edges. Throaty sound, but not harsh or raspy. No backfiring. And no weird resonance at certain RPMs.
Not too loud until you punch it, then it's off to the races. If you don't normally drive with a lot of throttle you will likely have no issues with these on the street, but that depends upon local ordinances and enforcement. With the windows up you can carry on normal conversation at cruise. Don't remember the brand, but I was happy with them.
I expect that you will drop 30 lbs at the rear of the car (at least). I took them off because I plan to sell the car, and expect it to be easier to sell with quiet pipes.
You may want to pair this up with a remapped fuel injection profile to get maximum performance. This is the case on any modern ECU fuel injection car with mufflers removed. I ran them without remapping the ECU, so I didn't get as much power as I could have, but they sound GREAT. If you don't remap the injection it will not damage the car. Porsche fuel injection does a pretty good job compensating for minor mods according to my Porsche mechanic.
Simple DIY bolt-on installation once you've removed your stock mufflers. No welding, bending, or fabricating required. Tips fit nicely into stock exhaust locations. These bolt to remaining stock pipes and stock catalytic converters using the stock clamps. Clamps are not included. These bypass pipes are very light weight, so just reuse your stock clamps, which are very heavy duty.
No scuffs, scratches, broken welds, or other mechanical defects. Polished stainless tips are shiny, and clean, with some minor staining at the rolled edges. See photos.
You can save some dough and not have to sacrifice appearance with this set.
Oval tip dimensions approx. 4.25" x 3.75". If you need additional measurements I can provide, but these will fit just like similar models from several other manufacturers.
If it's not shown in photos, it's not included.
