The only aftermarket one I've seen/heard in person is the Eisenmann one on Vic55's car. Sounded mean but he also has the secondary cats and perhaps primary cats removed. Someone that knows for sure will probably chime in.

OT, but...what rims are those on Vic's car?SDSilverM3 said:The only aftermarket one I've seen/heard in person is the Eisenmann one on Vic55's car. Sounded mean but he also has the secondary cats and perhaps primary cats removed. Someone that knows for sure will probably chime in.

there is a place for it on the SS system. dont know all the details cuzz i didnt install, adam would know better. i just remember him callin me and tellin me the system was done and no cells poped up. but he had to extend the connectors due to the sensor is farther backjangy said:I didn't know the SS system didn't hack into the ECU. What happens to your O2 sensors?
yes my ECU was done also. i just ment they didnt have to take the light off with the ECU.jangy said:That makes sense. You will need to keep an eye on the O2 sensors. Since they do not have the cats to take all the heat, they will likely wear out faster. Not a big deal, but something to remember if the light pops on.
I thought you had ECU mapping done as well, no?
I had the post cats and the resonators out with that exhaust the sound was crazy but because I lost back pressure I lost some power too. I put the resonators back on and lost some down low noise but up top its the same and car is stronger than ever.SDSilverM3 said:The only aftermarket one I've seen/heard in person is the Eisenmann one on Vic55's car.

It depends on how MUCH you have to spend...davidmatthewhernandez said:I didn't know AMG made stainless steel tubular shorty/long tube headers. What else they got in their sleeve?
