Hahaha we'll put

 

I'm pretty sure they'll pass smog just as easy as the stock engine considering the systems are made to work with California regs and they are the worst place to modify vehicles. The LS or Hemi would get better fuel mileage compared to the RIPP on a stock engine easy. There's no question about that. The V8s aren't that heavy and the power to weight ratio is far better than the stock JK engines. Most V8s I've seen are getting 20+mpg in a JK compared to 15mpg for the average JK once lifted with bigger tires. I know guys with tuned LS getting 26+mpg. My 6.1L was also great on the highway for mileage, but horrible in the city...especially if I gave it a bit here and there.

I loved my 300 SRT-8 with the 6.1L, but when push comes to shove the LS has been and is the most reliable engine built for a long time. There's a reason why Chevy's always go into Fords hahaha

Haha wanna make a bet

 

Believe California does the emissions testing with the sniffer in the tailpipe on a wheel dyno. Like I said, in MO we have a designated computer with government software that reads the VIN and certain engine emissions parameters that are set to the specific vehicle. Basically, as stupid as it sounds, they don't care what's coming out of the tailpipe, as long as the check engine light is not on and the emission system readiness monitors are set, it'll pass, but it also has to have a PCM that matches the VIN, typically if a PCM tune or reprogram is done, it'll set the readiness monitors to "not supported", which will cause a failure. Seen it a hundred times on mustangs, camaros, and ricers.

 

It's more like putting a 350 Chevy mill into a '32 Ford hot rod, which most of them do by the way.

$60 flowmaster super 10, resonator delete

 

All our newer..I think '92+ vehicle get tested by the port vs sniffer. Older stuff is all sniffer. As long as there's no engine codes present they'll pass it up here though. If it doesn't read it, it doesn't read it. I'm pretty sure we can only fail if an engine code is present. None the less our emissions program is supposed to be taken out next year.

 

Wish they'd get rid of ours, but it definitely brings a lot of money into the shop when a car fails. Ours is anything '96+, all vehicles require safety.

 

There is only so loud you can make a v6 sound. My glass pack sounds great but sounds nothing like my old 5.7 liter hemi with no resonator and an aero turbine muffler in a 04 ram. Now that was LOUD!!!

 

Haha well obviously :p a v6 is a v6. But to be honest, I've heard some of these big systems sound much ricy-er than a simple flowmaster or similar muffler. That's all.
