Re: High flow cats..worth it?

I've been getting an o2 code every once in a while since I installed the magnaflow cat, but thankfully i can just turn it off with my tuner. It only lights up towards the end of long trips.

What we do is use SparkPlug non-foulers. We stack two or three of them, put steel wool in the gap between them, and put the O2s in there. That reduces the flow enough that the ECU thinks the stock cats are still there and won't throw the codes.

Re: High flow cats..worth it?

That's cool and maybe an idea if I ever replace these. Sounds like the CEL is more of a PITA than anything, but still be nice to never worry about it!

Re: High flow cats..worth it?

Yeah, its just a PITA. Problem is, its an immediate failure on inspection.

I wish Chrysler put more effort into adding horsepower to the v6 instead of focusing more on the 4.7 v8 and 5.7 hemi (and also making you buy the v8 to get QT2 and QD2).

Re: High flow cats..worth it?

They didn't because the V6 is just there so they can say they have it. Kinda like the old 4 cylinder Wranglers and 4Runners. Almost nobody bought it. Its just for rentals and loaners. Economy was no better then the 4.7 or even the 5.7, and it makes way less power. No real purpose.

They had it on the shelf from the Liberty and Nitro, and it fit the GC, so they figured they'd throw it in for a few extra sales.

I cant imagine how a 4cyl Wk would be. I guess the v6 is a good basic engine, it seems simple to maintain and after a few add ons I.E intake, exhaust etc it makes it a little better. Ive done a few add ons to help with the power, I just don't want to install something that wont yield any results. Ive heard good things about porting the throttle body, I may have mine done shortly and call it good.

Re: High flow cats..worth it?

IF you get a supercharger fitted for it.. I believe there are a few people on the boards here that would love to know what you did.lol
