OK, so they are both un-catted ?
And the comparaison was only about sond level, not performance ?
Check my exhaust upgrade order please
Re: Check my exhaust upgrade order please
Both systems have a single cat in the midpipe, none in the header. This was an autocross event, which includes sound metering under conditions controlled enough to draw the conclusion that sound levels are the same. That's all, not a dyno day.
