I now have flowmasters w slp LT & O R X-pipe, I love the sound but the drone is killing me. Went on a 400 mile trip & now I need to change. Or is there another muffler w/ no drone? Any help would be helpful.
The Corsas are great. Just be warned that if you go with an offroad pipe (NO CATS) at some point, they will be LOUD.
I have also heard that if you add and offroad X or H pipe, you will have a continous "Check Engine" light on because of a catalytic converter sensor.
any O/R pipe will cause a check engine light (CEL). you are removing the cats, and need to compensate for it somehow. either MIL eliminators, or turning off the rear O2 sensors in your tune will do the trick. the MIL eliminators are about $60. if you ever plan to modify your car beyond simple exhaust mods, you will need a tuner anyway so you might as well do it right the first time f you have the cash. if money is tight, then the MIL eliminators will work with little cash out of pocket.
Thanks for the info. I was told that I would have to spend about $800 to add a Pypes O/R H pipe that would correct the check engine light problem.
So I bailed off & did it for the NO DRONE issue, The guy @ the muffler shop said they would be extremely loud w/ my O R X-pipe, so we will see on thurs. Also gonna try the pipes mandrel over the axle pipe. I wll give a report asap.

the guy at your muffler shop is a smart dude.....
The Corsas with an offroad H pipe are LOUDER than the Borlas with the same pipe. Funny, because with the factory catted midpipe, the Corsas were much more quiet than the Borlas. Once you start moving air thru the Corsas, they open up and scream like a redneck at an opera!![]()

YES they are! No drone & an awsome sound. Little loud but sound better than any other modular stang muffler I have ever heard.![]()
