Looking to buy a test pipe and down pipe for my X. I have the invidia N1 catback and was wondering what test pipe and down pipe you guys would suggest

 

AMS o2 dp and tp!

 

I agree with the AMS DP, but to be honest, a test pipe is pretty much a test pipe. It's a straight piece of pipe, that should have a 3" diameter. Pretty much any brand will do the job.

 

For the DP I'd definitely say either the AMS or the ETS for sure. Others will recommend the Rexpeed o2 DP for the cheaper price, but the downfall there is that it's not cast like the AMS. Like mentioned above it doesn't matter what test pipe you get honestly. I'd say get a cheap Megan TP even. Do make sure you get yourself a tune + a wideband guage after getting these parts though! Good luck, I'm sure you'll enjoy!

 

If you're looking for just a downpipe and not an o2 elim check out the cat-elim Invidia downpipe (replaces stock downpipe and cat).

 

im getting my catback and test pipe installed this weekend. and i had not planned on a tune or any guages. do u say get the tune just because of the extra smoke tht will come out?? or are there other things to be concerned about?

 

I agree. I have the invidia q3000 and the invidia dp/tp. It's nice because it's all one piece, decent price, and works great

 

Overboost and Lean condition will occur.

 

Thanks for the replies! So far im leaning over towards the ams o2 dp and as you guys mentioned probably going to get any testpipe i can find for a good price. And i will be getting the tune and wideband gauge as well

 

Well tht isn't good. Maybe I should go ahead and get intakeand uicp. And get my tune.

 

Anyone know of where or who I can get the ams downpipe for a good price?

 

Check out the vendors section.

 

If you don't get the 02 DP then don't bother you're wasting your money.

 

Same diff, just get the dp and tp and tune OR get the dp, tp, intake and intercooler kit all at once and then tune

 

Agree with either ams or ets dp, and any tp
