Long tubes question
Simple question, but have yet to see it answered...
I always see people post that if you have emissions, dont go with Long Tubes because they relocate the cat... What if there is no visual inspection of the cat placement (because theres only a handful of F-Bodies over here).
Do the LTs change the gas flows to not pass emissions?
I can post my emission results/requirements if that would help anyone tell me if I can or cannot pass with long tubes.
Thanks in advance.

well you got to figure that most of the people working in the shops arent going to know about every car, and where the cats are supose to be located.
i've herd of people having issue with the cats not heating up enough to be effective... but i've passed with long tubes and cats without any issues.

You can't relocate the cats too far away from the engine or they will not heat up enough to work properly.some places are okay as long as the sniffer is happy.In the Y is fine.

After reading this thread, and thinking about how emisssions testing plays such a big role in a lot of peoples choices for vehicles...I think we should create a list of all 50 states and weather or not they have emissions laws and if so, which ones (sniffer, visual, ect...). Anyone else think so?

Well Im sure in Europe you dont have to worry about the location check at all... And Im not even sure with the 95 where there is only 1 cat if the cat moves at all, just thinking about the sniffing.
