For the price it can't be beat!
I got this during the black Friday sale because my current catback has seen better days. I purchased based on price and it was so cheap with the sale I could not pass it up. Now, I have heard MAC on many stangs before, and always felt that it was directly comparable to the same chambered tone of a Flowmaster; with just a cheaper price tag. I was correct in my assumptions and the sound is just right for me. I have shorty headers and an O/R H pipe and this 2.5" catback sounds around the same volume as American Thunder, or Pypes Violators.
I have no drone that I can detect, although I do have 4.10 gears which puts the RPM's a bit higher at cruise to where you don't get much drone from 2 and 3 chamber mufflers anyways. I tried to cruise at around 2,000rpms to duplicate the drone I had with my Flowmaster 40 series at that RPM and I do not hear anything, so I am assuming that this exhaust system has no drone issues.
Inside the vehicle the exhaust is very mild, you can have a conversation on speakerphone or hear your radio without a problem. No vibration issues or excessive heat coming into the cabin, I drove for an hour and felt the carpeting and it was not even warm.
The quality of the system is excellent, all welds look great, all mandrel bent and utilizes ball flanges at multiple points to not only make installation over the axle easier, but allow adjustments to be made that on other catback systems may not be feasible.
The system comes with the hardware for the catback itself, you will need to either reuse your existing bolts to mount the catback to your mid pipe, or purchase new hardware. The bolts are 7/16" thread by 2.5-3", or use metric M10, in a good quality stainless. You also will need to either reuse your existing rubber biscuit hangers or purchase new ones as well.
The exhaust tips are clamped on, which I first felt was cheap and tacky, but I was wrong and I like them. The fact that the tips clamp on allows for some fine adjustments of how deep you want your tips to be, or how much you would like to make them protrude from underneath the car. I managed to get them to protrude roughly the same as stock on my 1995 GT, or about 1.5" with no problem. Just work slow and allow yourself time after install to go back over everything and make adjustments if a part of the exhaust hits the undercarriage or suspension, then when all is well you can re tighten everything.
As far as performance is concerned, I never have noticed any performance gains from catbacks on any car, even if a dyno shows some marginal gain of 5rwhp or so, you can't feel that anyways unless maybe you are the Stig or something. Let's face it, we buy exhaust for a Mustang for sound and to make statements, and this does not disappoint, it is neither too quiet or too loud, won't set off car alarms but it lets you know that you mean business.
I would purchase this system again and recommend to anyone that wants an aggressive tone without the high price tag associated. I also would recommend this exhaust for looks, the 3" stainless tips with a mirror polished finish look great and I can't stop turning back to see my car every time I park it. Thank you American Muscle!
