Well, I bought an Invidia Testpipe + CEL fix and intalled them 2 -3 weeks ago in my 2000 S2000 with the exhaust of 2005 S2000. Everything is great, the car sounds good after the testpipe in but there's some funny smell like gas smell. and it's freaking stinky when I leave the car at Idle or stop at redlight. Anyone have the same problem?? anyway to correct it?
note: the smell come from the exhaust, nothing is leaking anywhere.

 

yeah.... that's what test pipes do. with the cat gone all your unburned hydrocarbons are coming out your tailpipe instead of being intercepted by the cat. how to fix it? put your cat back in.

 

Now the lessons start... Yea, there always give and take when modding-just gotta figure what you are willing to give to take. Good Luck!

 

It's normal....no fix for it.





peace

 

yup all my friends cars have that same smell, my s2k has it to, im just gonna run race gas and clean the motor out.

 

Welcome to the catless smell of the S2000.

 

yeap... it smells and about a month or two youll notive some yellowish discoloring on your exhaust....

 

That smell is cancer invading your body!

 

LoL thanks guys, I was thinking there's something wrong with my car but I guess not. And yeah, notice my exhaust tip turn in yellow/brown too. Thanks for the info guys.
ps: but the smell is so freaking stink ...uhhhh

 

Doesn't really sound worth it to me then... Doesn't anyone out there make an aftermarket cat for our cars or is it a moot point??
