Okay, I had some Helix test pipes installes and have read about the smoke or exhaust fumes. I don't have smoke, only an unbearable exhaust smell when I'm in a standstill with my windows down. I can even smell it when I'm driving. It's okay when the windows are up. I don't see or hear any exhaust leaks. I know the pipes came with an additional hole. What is it for and should I have some special gasket ot something to seal these better? I'm not sure if this is the problem but just covering all my bases. Thanks.

 

it is normal
my exhaust still stinks after...
after 1.5 months of installation!

 

Yea, i just installed my SES and Resonated test pipes and when I drive I get light headed....yea, I dont think this is normal

 

you removed your catalytic converters... its gonna smell...

 

+1. One of the purposes of the catalytic converter is to burn excess fuel not completely burned in the engine. You removed the catalytic converter. Think about it.

 

Yup. I don't think those exhaust fumes are too good for you. Go with HFC's.

 

i love the smell, you'll get used to it.... btw, thanks jason on those other parts for the clutch pedal for my S14

 

oh I love that smell...

I am picking up a 96 S14... Ill know for sure about it tomorrow... I cant wait..!~

I have to convert it to manual... but im going back and forth between SR swap and KA Turbo... hrmm...

 

I like the smell to lol Crunk fumes rule...they make you drive faster On a serious note, I have Helix TP, and the fume strength considerably descreased after about 600 miles or so. I can't even smell it anymore, even with the windows down coming to a stop. Give it some time and you'll really be suprised.

 

just got used to it...

killed the brain cells that sence the fumes...

:P
