does any one have test pipes on there car. i just bought helix test pipes and was wondering if i install them will i get any codes or lights that will come on. or do i need to do something so that i wont get the light to come on

 

i have helix v2 test pipes... never had a light when they were in ... i took them out to pass emissions tho

 

oh really cuz thos are the test pipes that i bought to. how do you like them, are u able to notice anything

 

I have Helix V2 pipes. Great bang for your buck and an excellent first mod.

You'll need to get the o2 bung extender things (non-foulers) though so you don't throw a CEL.

 

oh thats what i thought. where do you get those non-foulers at

 

The "official" part name is: Spark Plug Non-Fouler

Here, read this thread:

i never got the non foulers... and i never threw a code.... i also didnt really notice anything because my car was sooo ungodly loud it hurt

 

i couldnt tell if i was going faster or just making a sh*tload of noise

 

I have strup test pipes, It's only been on the butt dyno, and i feel more power mid-high end. it sounds amazing too.

 

test pipes make your car smell like gas fumes, I think they only help if you are FI, unless you like a loud exhaust

 

stinky stinky stinky and check engine light! But sounds badass!

 

I'm running Invidia TP's and bought CEL eliminators off Ebay for around $15. Never thrown a code but then never ran the pipes by themselves either. They really made the exhaust louder with a hint of rasp between 3500 and 4500 RPM. The cats were my major chokepoint having already done Borla headers and catback. I actually enjoy the note of my system but I've scared a few cyclists, especially when I downshift to pass them

 

For some reason 03 and early 04 VQ35's were the only ones that didnt throw off the CEL

 

so did 05's throw a cel.

 

06+ due to wideband vs narrowband 02

 

oh so i have an 05. will i need the non foulers. and if any can tell me where they got them and what size they got.

 

 

If you're that worries, why not just go to Pep Boys and buy some for $10-20?
