Im buying a used magnaflow x pipe for 250 I already have GT500 axelbacks will this make A big sound difference?
if it is the cat delete one and you actually delete the cats yes. Else wise not really. Sound might be a small bit raspier. Will not be louder.Im buying a used magnaflow x pipe for 250 I already have GT500 axelbacks will this make A big sound difference?
Are you talking about this one?It is the one with the cats so you think its worth it?
yeah if you use the whole thing, including the down pipes without cats, 100% worth the money. You car will get really loud on WOT but with the GT500 axle backs not be terribly loud at cruising.Thats it the offroad x pipe
no, you'll throw CEL codes always when the car is on as the 02 sensors will detect that the cats are not "working." The car will still run fine, but you'll always have the check engine light on. With a tune the 02 sensors can be turned off so this doesn't happen.Is there A way to get around tuning it dont want to.void warranty
I would also say that tuning your car after significant modifications is NOT just to keep your car from throwing an engine light. If u make modifications to the exhaust and remove the cats, the car NEEDS to be tuned to correct the air/fuel ratio. You could actually do damage to your engine if you choose not. You will also squeeze a few more HP and improve throttle response.no, you'll throw CEL codes always when the car is on as the 02 sensors will detect that the cats are not "working."

also removing the cats technically voids your warranty too. It is technically illegal to remove them, but many of us live in places that don't do EPA checks so we don't have to worry about it. Other people have people that will "pass" them so they don't have to worry about failing emissions checks.
You'd know if you do. You'd have to once a year take it to a station and have it very emissions. Some places do a visual check all places do a sniffer test. I don't think Texas does but not sure.So you happen to know if Texas does those checks
My understanding is this is not correct for the 5.0L engines. They do see somewhere in the ballpark of 15-20HP gains but I was told more than once that removing the cats with the 5.0L engine only throws a CEL code. Not that you wouldn't want to tune it, but the car automatically adjusts to the cats "failing"I would also say that tuning your car after significant modifications is NOT just to keep your car from throwing an engine light.

oh yeah? Have sources? They have tried to bring E-Check to my area a few times and been told to GTFO every time by a huge margin.Emissions testing is coming to every state. You can thank the young punks with diesels, that think It's cool to blow black smoke everywhere.
It's coming just like helmet laws. When the Feds pull the road money, everyone will cave.nosympathy said:oh yeah? Have sources? They have tried to bring E-Check to my area a few times and been told to GTFO every time by a huge margin.
I'll do some research. So your saying that when the ECU detects that the factory catted H-pipe is removed and throws a code, it automatically 're-maps itself to compensate for the high flow back end?You'd know if you do.

I honestly am not sure on the details. I was advised by American Muscle and a few big time members on here when I switched to my O/R X that if I didn't have a tune for that it would still run fine, but I would just throw codes. I was told that being tuned for it would allow the better flow to be utilized. I never ran it like this though as I had new tunes from AM/BAMA come in the day before I installed my o/r x.I'll do some research.

I had the magnaflow true xp and it was very loud, and I loved how loud it was but it was also very raspy, and I hated the sound of that..just my two cents.if it is the cat delete one and you actually delete the cats yes. Else wise not really. Sound might be a small bit raspier. Will not be louder.
it is my understanding that the front O2 sensors (wideband) are used by the PCM to adjust AFR, and rear sensors are mainly to determine cat function and are not used for engine performance. Thus, they can be safely turned off.I'll do some research.
