Default UPR or Pypes

Finally going to order my X-pipe within the next 1 or 2 days...
I'm going with an O/R pipe because I don't need to worry about admissions.

UPR pros: tru-X design and good ground clearance
Pypes pros: Stainless

UPR cons: Aluminum (I could coat it w/ VHT paint to protect it)
Pypes cons: Clamshell design

What would you go with?

i have the pypes o/r x, and i love it. i've had both, and the pypes easily wins over the upr. i think upr is kind of cheap. thats just my opinion, but i would definitally go w/ pypes

heres a vid of the o/r x:

Nice..
I'm actually worried about the lack of backpressure without cats--I heard it reduces low end power but increases power in high RPMs, but I'm pretty sure the power stays the same in the low range but just feels slower because the top end gains so much more. Am I right on that? Because I don't want to lose any low end power!!

i love my pypes. i just got it and put it in with some frpp headers, stainless, inexpensive. oh and btw anyone with a car 96 and up emmisions testing is just plug and play. no tailpipe tests, so get a tuner or mils and you are set.

seems like a lot of people like the Pypes...
I'll try it out.

I'm going to get the O/R Stainless X...do I need O2 extenders or MILs or anything else when buying the o/r X?

They Dyno will show a loss of low end power by a few HP but you gain it all back in the higher RPMs + some torque

low end power doesn't really matter too much in drag racing , because once you are out of 1st , you never get below 3000 ish anyway. top end is where you want it

6of one and 1/2 dozen of the other; unless you live in a snow and ice and salt the roads place--then stainless wins every time...
