UPR X-pipe installed

[2soon2boost]

I just installed the upr catted x pipe on my '97. The only real problem was getting the stock h-pipe off and out. If anyone wants to know:
Exhaust manifold flange nut is 18mm, the cat-back bolts are 13mm,and thread size on O2 sensor bung is 18m-1.5.
Job is made easier with atleast one 6" and two 3" extensions and a universal joint. Also, have both 18mm standard depth and 18mm deep well sockets, just in case.

Also I bought the catted X-pipe and it has yet to trip the MIL... I was expecting to make my own MIL elims, but not needed! I guess the single cats are enough for '97.

Also, wow this car picks up now, and improved both low-end and top-end performance.


Overall impressed with this purchase!

Is the UPR stainless or aluminized pipe? Can I ask how much you paid for it?

 

[2soon2boost]

It is aluminized. I had to tap the threads on the O2 sensor bungs, but other than that it was a pretty easy install. It is $300 with the hi-flow cats. but sn95 has a discount through upr...

i put a upr catted x on my 03 mach 1. it has been on for a year and has not set any codes. You will be fine. I just put a bassani catted x that has super tiny cats compared to the upr catted x and that does not trip any codes either.

man! if bbk and alot of the other big name companies would make stainless mid pipes along with the aluminized theyd probably get alot more business! id LOVE 2 hav a stainless bbk o/r X! but i think i'm just going to get a upr o/r X(wish it was stainless!) but i wish they had more stainless 1s besides pypes, bassani....

i found a used catted mac h-pipe and it was alright until i got the O/R X. ill just turn off the o2s. no big deal.

UPR is a pretty quality piece IMO. I got the catless x and turned off my rear 02's with an xcal2.
I paid like $105 shipped for mine on eBay brand new... Its pretty surprising how much money you can save sometimes...

I think the x pipe and the PI intake were the best 2 mods I did so far...
