Test pipe
 

Hi everyone, I wanted to know if there's any test pipe that won't turn the check engine light on?

It's not a guaranteed thing with any test pipes, although some come with extended O2 bungs which definitely help / delay the light coming on. Also, packing said bung with steel wool has been known to help as well.

Fast Intentions guarantees no CEL with their products.

"•(Standard) J-Bend style O2 sensor anti fouler to ensure the CEL light STAYS OFF."

if you do throw a CEL with their products they are great with working with customers to resolve the issue. typically it's due to improper handling of the O2 sensors during installation of the test pipes.

W/out a REFLASH....
N ur dreams there mite be one! ;)

incorrect.

I ran my FI test pipes for a year prior to my tune and never had a CEL.

I have almost 35k miles running FI test pipes and CBE now and never had a CEL.

when you go for quality parts (fast intentions) then you can expect it to work as described.

Me too, ran well over 50 miles (time for the ecu to ready) and couldn't get a cel with berk test pipes. A good test pipe will have a very very hard time to throw a cel. But just reset it and it will be a long time if even ever you see it again.

When you first put the TP on, did the smell bother you?
And does it eventually go away after you break it in?

no love the smell. I smell it even more now with straight pipes. I grew up at the drag strip with my father so that raw exhaust smell, burning rubber, and race gas all seem like home to me lol

no it does not go away. the cats filter ll the poison out of the exhaust (well as best it can) for emission and safety reasons. without the cats all that comes through unfiltered. hence the smell but more so the powahhhhhh :tiphat:

I had a CEL with my Top Speed test pipes at first (after 150 miles) but I reset it, hasn't come back since. Love the sound, hiss, smell, and power :tup:

Did you install the test pipes yourself or pay a shop to install? Z1 just quoted a friend $216 for labor.................. Maybe just me, but it just seems a bit much to put on test pipes.

Demon Bolts. Search it and you'll understand.

I had a local guy do it for $100. There's no way I was going to try the demon bolts myself after agreeing on the install price.

they are the worst. install of the TP and CBE took 10 minutes. demon bolts took 3 hours to get off.

Dam!!! Thanks Guys, so i guess its safe to say "Pay Z1 to do it right"?

it cost me $100 for the TP install... i got about 80 miles on FI RTP w/o CEL.
