Do you put the cat back on when you need to have your emissions done? In MD we have to do this every 2 years.

 

If they put something in your exhaust when they test it then you probably wont pass. If all they do is plug in the OBD2 plug under the dash, and you don't have a CEL, you will pass emissions with the test pipe on. I'm in IL, we only get it every 4 years.

 

Thats it? that thing is tiny..what was there before that, a cat? what kind of gains do you get from that thing?

 

berk says 4-5whp from there test pipe im thinking thats true with supporting mods. and yes the cat was there before same length just alot thicker and test pipe weighs 5 pounds vs 13 pounds for stock cat

 

Lol, what did you expect? The 70mm is already bigger than the 63 too!

 

That built in cel fix doesnt work! U'll get a cel after 40 miles. U still need the extender piece.

 

If you also have Invidia 70mm N1 installed, with stock ECU... You'll definitely going to have a lean mixture. That will make the car much slower.

 

i just ordered a Berk Technology test pipe yesterday. I paid the extra for the peice of mind that their CEL fix works 100% on pre DBW cars.

plus they had a st. patties day sale so i saved 20 bucks!

 

i have the same tp I get a cel while cruising on the highway. I have not installed any extenders/washers yet, but I guess I will. The cel doesn't bother me to much. Except the tp is supposed to be cel free. BS

 

you should sue them for false advertising












NO not really.....
