My exhaust was rotted to **** from the cat back, since I was busy I told my dad to go get it replaced. In attempt to save me money, he went and got some crappy non mandrel bent piece of crap piping. Now, maybe I'm paranoid but I swear I feel a small lose in power. Anybody have a realistic idea on how much power this crappy piping is sapping? Thanks in advance.

 

what size did he get?
hopefully he stuck with at least the stock diameter...

 

Isn't stock pressure bent to begin with? So I don't see how you lost any power...

 

ur just paranoid. unless ur heavily modified you'll be ok. i just got mine done and i went with 2.5 crush bent piping from the cat to the muffler and i feel my car's jumpiness in the low and mid range. no resonator.

 

5psi per bend!

 

If you're auto and he got bigger piping, you probably did lose some power. But then again, it might be all in your head.
