is the testpipe direct bult on to the stock exhaust sytem or do i have to purchase and additional parts? also is it easy to install the testpipe and one seen DIY for testpipe bc i cant find it

 

It should be direct bolt

 

I know that the ATP test pipe bolts directly to a stock exhaust. Soak the bolts and 02 sensors with wd40 for 24 hours befor you plan to install it that will help you get every thing loose.

 

Our test pipe is a direct bolt on replacement for the catalytic. Everything is included that you need, no extra parts needed.

Order before 2/19 and get our special introductory pre-sale pricing!

 

most test pipes bolts on to replace tha stock catalyst. it just depends which test pipe you installing!

 

PS good luck w/ inspections. lol i used a high-flow catalyst on mine instead of a testpipe

 

Dangit i cant believe i missed this thread. Ive been lookin for a reasonably priced test pipe that doesnt have ecode tunings insane shipping costs and recent soso customer service. My Bday is around the corner and there is nothing i would rather spend some bday cash on than a test pipe! Maybe I can still get the special introductory pricing??!?! Ive placed several orders with them over the last year and they have always been great with very reasonable shipping costs. Come on Mike! Its my birthday!!!!... Almost....
The only thing i question about the purems tp is, is it 2.5" all the way through? Cuz the turbo is a 3" dia where the cat/test pipe bolts on. If it goes from 3" to 2.5" (without a smoothtransition) that creates a boundary layer that will cause turbulence... Hmmm.
