I'm debating whether or not to run a test pipe when I have my turbo installed. Will there be any extra smoke of an unusual color when I drive this way? I don't want it to be too noticable. How bout the sound and the odor? Thanks.

 

its louder and it really smells like shish-kabob... iv been behind cars without cats and actually had my eyes water... of course they were running rich... u can tell many times when someone isnt running a cat... if u know what to look for that is

 

No extra smoke or anything. The fumes suck though if you are behind the car. Oh well, it's worth it.

 

yea if you park in a garage inhaling those fumes makes your eyes look like you're stoned..

 

my car is smoking, and was told to put the cat back on and hook up the second O2 sensor. Im debating on whether this would fix my problem.

 

my car emits a gray "rich burn" smoke at WOT.. but not at any other time...
here is the tell tale sign of a turbo car with no cat

 

dude...is all the sut on your car from the exhaust?

 

OMG it looks like you were tryin to climb a dune

 

my car only spits black smoke on a WOT run. no cat,resonated test pipe here. the smell ISNT that bad,only ifyou stand behind the car or something.

the only way i can describe it is it kinda smells like a big ol catless v8 truck but not as strong.

 

A little off topic but is there any way a cop know if your runnin without a cat??? Like any signs from sound or exhaust fumes????? Cuz I'm in CA and not sure if its worth it to run w/o a damn cat and get the big *** fine Thanks for all help.

 

yeah my car looks the same. its so hard to get off i have to clay bar the car every other week to get it clean

 

Jees. I have no cat but I do not have that problem. Maybe because my car is black.

 

yep... and thats not even nearly as bad as it was when i was using a FMU
what sux is if it sits on there too long it starts to tarnish the bumper... im able to get it off of the rest of the back of the car... but its a real bitch. it doesnt just whipe off or anything

 

I run no cat or resonator.. it is not that loud. smells of gas a bit and looks the same as the R does in that pic. I just wash it once a week
