hello, I have a typical 2005 v6 mustang that I'm looking to make louder. A couple of my friends have straight piped their cars and it sounds so much better. I've thought about doing it but I'm not sure if I would be able to. I have center exit dual exhaust on my car so I'm not sure if anyone knows if it is able to be done on it efficiently or Not?
I have a 2011 3.7 v6. I don't know if the 4.0 is like my 3.7 but, when i run my Magnaflow competitions which are straight pipes with Magnaflow tips, i lose a lot of low end torque. I have to give a lot more throttle to go up hills when compared to my Magnaflow Street Series axle backs.
Most muffler shops should be able to do your straight pipes if you go that route. Good luck
here's a picture of what it looks like
