Anyone else feel like they might have lost some Tourqe with a non catted x-pipe? I have UPR x pipe and stingers, and I swear I lost bottom end TQ. Is it just the lack of back pressure maybe?
Loss of TQ with non catted x-pipe?

This is commonly reported here. Loss down low. Gain up high usually only with a highly modified engine. Stock cats really aren't too restrictive.
I had a Magnaflow catted X. The torque loss was so great, I pulled it off a couple days later and got rid of it.
I went with a UPR O/R X-pipe and I'm averaging 1/10th quicker in the 1/8th . In warmer weather the car has picked up time . Feel wise I can't tell a difference track wise I see it on my slips . So bottom line it helped me .
you'll lose a little down low but gain more then it back up top.
well i see that im not the only one that noticed the loss.
