California Emissions Question RE: Mid Pipes
Hello, I'm having trouble deciding on the right mid pipes for my 05 GT and could use a little advise. With California Emissions standards being what they are, I can forget about removing the cats or getting an o/r pipe. [:@]I'm thinking about getting the Magnaflow Tru-X X-Pipe, though if I can get my hands on a H-Pipe with high flow cats that would be my choice.
I just purchased the car and I believe everything is stock except for the Borla catback. My question is, what is the best I can get sound/performance wise that will still allow me to pass smog? Visual inspection is not a problem.
Thanks

As long as the Cats are CARB approved you're fine.

RE: California Emissions Question RE: Mid Pipes
As far as High flow cats go, they suck.... They burn out too fast and don't flow much more than out factory pieces.
Second, why are you going through all this trouble? You wont get mush power out if any. Are you looking for more sound? If so, swap out the mufflers maybe even consider mid pipe style for the deeper sound.
Trust me the stock components on our exhaust accually flow pretty well. No need to change anything but the mufflers!

The MagnaFlow Tru-X with high-flow OBDII cats actually works pretty well. Not cheap for the power gain but if you want to max out your N/A power this isa requirement to work witha set of good equal length shorty headers. The total systemincrease for the JBA headers and MagnaFlow Tru X-Pipewith stock mufflers was 18rwhp on a DynoJet using SAE correction and smoothing set to 5. That is 18rwhp out of parts that yousaynobody needs to change with the one part you claim people need to change still in the system. The stock mufflers on a stock exhaust system on an otherwise stock engine are worth 2-5rwhp and on a free flowing system like mine worthabout the same2-5rwhp which I confirmed by replacing the stock mufflers with MagnaPack cat backs andputting the car back onthe dyno again. This system which you and so many other ignorant people claim doesn't work helps my '05 GT manual put down 316-318rwhp SAE smoothing 5 onthe DynoJet. This samecar with 1,000 miles on it put down 263rwhp on the same dyno when bone stock after an oil change. If these parts didn't work where did that extra power come from?
HTH!

All I am saying is if you are modding the exhaust on a stock motor, then let it be for sound and not power as mostpeople are not going to notice a 7% gain in a 300 horse motor
