how does a test pipe strip your o2 unless your forcefully cross threading it?

 

dont know...i put em in by hand and didnt even have to try....i tightened them down by hand and torqued em the rest to factory specs. i have no idea but i hate my test pipes...im gonna pull an Office Space printer scene on them when i get some HFCs...(and new sensors )

 

My t-pros tp's broke right at the header flange during an HPDE. They are crap just like megan in my opinion. Had them welded at the track and they just cracked on me again. The tubing is simply too thin to last. Just pick up one of their test pipes or y-pipes and you can see how light they are. Simply not made to be durable and stand the test of time. I also had a TPros y-pipe crack on me at the collector. Garbage I tell you!!

 

That's exactly what I was thinking...

 

just installed TP test pipes, TP y pipe, and a PIT exhaust....by far the cheapest exhaust combination evaialible for our car........and it sounds alright, only problem is that i gota leak somewhere INSIDE the PIT mufler just before hte exhaust tips....so it makes this SLurping sound of air returning back after i let go of the throttle.....
other wise it wouldnt be bad, i kinda like it. ...but it drones like a mad man.

 

Modding your Z and saving money just don't seem to go together. I saved a lot of money, but......

 

Well um..
I have a set of APS TPs for sale! lol! PM!

I used to have megans but i didnt have a problem with them. However, i could tell it was a crappy product.. Tpro is also megan btw..they're the same companies. Megan is the 'higher' end version. lol/

 

I assume that goes for thier cat backs as well?

 

nothin a bead of weld cant fix
