Pypes catalytic converters
Hi guys. Installed the BBK shortys with the FRPP cut and clamp x pipe. Already had the flow master force IIs installed. Car sounds louder and throatier from outside the car. Take offs are much deeper. Inside the car, not too much louder but definitely noticeable. Idle sounds nice, can definitely tell the exhaust is not stock. My question is, if I was to get these Pype converters, will I notice a louder exhaust? Like the sound of the exhaust now but I do wish it was louder. Got the rumble and the deepness sound down, just want some more noise. American muscle has these for about 275.00. What's everybody's opinion on these high flows?
I know BBK makes a catted x, but it's a little too late for that considering I have the FRPP cut and clamp, but I read reviews on the BBK that it's a lot louder. Will it be the same with these?

it will make it a tad bit louder yes. the bbk catted x will flow a little better since the curves are smoother and sound a little deeper since the pipe is a little bigger. also there is a curve that takes place in the stock cats so it would be hard for the cats to get welded in without cutting up higher than the cats so you can make that curve before the cats.

It will be louder. Don't be surprised if you have to have your o2 sensors turned 'off' on your tune. My tuner told me when i got a 'check engine' light, "some high flow catts don't work all that great and sometimes they throw a 'check engine' light.
If you live in an area that have smog test, you might not want to change the catts to the small high flow ones. Just my opinion

Well from what I was told, as long as the converters don't throw out a check engine light, they will be legal. American Muscle told me that these specific high flows, and so did a local dealer. And even if they did, I still have the tuner, so I should be good right?

if your state doesnt do the sniffer test thing and only does visual and the obd2 testing then if your check engine light is off then youll pass IF your o2 sensor sensitivity wasnt changed in your tune if you tuned it. if it was changed then it could still fail with out the check engine light off. with SCT you cant really turn off the rear o2's you just change their sensitivity to where the check engine light wont come on.

Hey,
If you were to get these, as CVH stated, you may need to drive several miles before knowing if the car will throw a code.
Generally these don't throw a code, but every once in a while, a car will have a more sensitive set of rear O2s and give a code. The car will not have a code right away, it will need to go through its drive cycle before throwing a code. This cycle will vary from car to car, but generally it is about 30 or less miles of different types of driving. Also, in the chance that your car does throw a code, it can be easily corrected with a tune to fool the rear O2 sensors.
I hope this information helps, and if you have any further questions feel free to get back in touch. Best of luck!
-Dan

I have not notice any bad effects from the new tune with the update for the cats.
