So my 70mm Toda exhaust just came in. I'm in no rush to get it installed since my car is put away for the winter.
So now I'm on the fence between a test pipe and a high flow cat.
I'm not concerned about the CEL issues. What I am worried of is getting pulled over due to the smells it would be putting out. So that'd where a high flow cat would come in I guess.

For you guys who are running test pipes, any issues?
Should I just stay on the safe side and get the Berk high flow cat?

 

according to berk the flow difference between a hfc and test pipe is small. If your going for 70mm your probably looking for all the performance you can get. I have never heard of anyone getting pulled for a test pipe, however if the officer knows what to look/smell for its easy to find. Just curious what would have with a testpipe at a mto spotcheck? (which are far and few between)

Are you going to get a defouler or run it with a CEL? how are you going to see if you have a cel?

 

Shame on you - polluters

 

If I do get a test pipe, I have a scanner tool for CEL. As for getting around the CEL... I may look into resistors to change the voltage. Make it think its leaner than it is.
So far I'm leaning on a high flow cat though.

 

I am surprised more people don't get pulled over for test pipes, if you are ever driving behind one it is so obvious who is not running a cat. converter, I've got to think that cops just don't care unless you piss them off by street racing or speeding in general and then they go looking for anything they can. I spent a day driving behind a few catless S2000's and the smell is obvious - like a dozen lawnmowers in front of you, lol.

 

Hey Ryan, Lets try to tour next summmer more yes?

 

I'll ask my brother about this Test Pipe thing... he is OPP - see what they really do about it.

 

Yea I think it's pretty easy to notice a catless car.
I remember following a couple catless cars during our niagara meet and it gave me one heck of a headache.

 

I now there are plenty of portable meters out there. I'm sure there are some cops out there who have access to some.
I have a combustion analizer that can read exhaust gases.

 

Oh for sure!
We should try the Turkey Point area.
