Couple of quick question's, I just installed a set of helix test pipes and I keep geting a gas smell. Im runing stock y pipe, stock cat back, helix test pipes and a k&n typhoon intake. Is is safe to run this setup without a tune? Also i double checked all my gaskets and o2 bung for any leaks, but i still smell gas. Any ides as to what i can do to not smell it every time i stop?

 

its gotta be a leak from one of the gaskets or a crack. i highly doubt an o2 bung would produce a noticable smell unless it was totally missing...

 

Test pipes smell...especially if oiled or otherwise coated....did you use o2 sensors in install, or how'd you do it?

 

That's kinda what i thougt... not sure what the problem is.

 

Yeah, im using the o2 sensor. I did the spark plug de fouler trick. I only used one though. instead of two that the thread i found recomended. I have had this setup for about 200 miles now and no check engine light

 

What you are smelling, is called exhaust fumes. Welcome to test pipes. If you can't live with it, reinstall the stock cats or try high-flow ones.

 

 

Test pipes = gas fumes

 

Sound's like im just gonna have to deal with it...

 

you could always go for high flow cats if it bothers you. drive around for a while.

 

I hardly notice the smell anymore. And no one that rides in my car ever notices. When I do catch a whiff of it though, it puts a smile on my face.

 

lol

 

I thought about going that route, but what's the power difference between test pipe's and high flow cat's.

It's starting to get better, but i do admit that sometimes it smells good!

 

hard to say for certain, but I imagine HFC's get about 80% of the gains test pipes get.

 

haha brain cells exploding!
sniffing gas is awesome.

 

Yeah, and 4 times the cost.

 

it's hard to put a price tag on being a tree hugging hippy and the piece of mind for stayin legal!
