Product Reviews

Took a week to get these. Which is not the norm from Steeda. Installed in an hour. No leaks! Sounds Amazing. FYI you will want to update your tune. Ran very rich until my tune file was updated. Easy 10HP for $140. My only regret is that I didn't do this mod sooner. Thanks for the help Frank! You guys and your products are by far the best!!!

These deletes were a perfect fit. I used a little high temp copper gasket maker and abolutley no leaks. Went with these because read a lot of bad reviews of other brands that tend to have leaks. Easy install after getting the stock cats out. They would have gotten 5 stars if they were stainless steel, but they also wouldnt be at this great price they were ss. At this price and fitment, you cant go wrong.

This part really wakes up the sound of the GT. It was a pain to install but with the right tools it can be done in a couple of hours. Don't forget the tune after these are installed. It is really loud!!!

Very nice product, installed on my 2014 GT. Took longer than an hour to install on a lift. Makes the car louder and you can feel a little extra horsepower. Steeda states 11 to 15 RWHP improvement. Excellent power improvement for only $140.

Big difference in sound and really easy to install. The perfect solution to making your car louder!

What an awesome way to not only increase the sound of the exhaust but also free up some hp!

Easy install. Fits perfect! Really woke the car up! Bang for the buck is a 10!Highly recommend this product

Quality product! I had these installed today and I must say the fit was perfect. The car runs great and the exhaust sounds awesome.
Great bang for the buck!

They are made really good and are easy to install. I have had the bbk delete pipes and these fit betterat the x. Only thing they could have done better us add a set of good clamps.

These pipes rock! They are a total transformation for not only how your mustang will sound, but also how it will drive. I have only installed them and started the car to check the sound. I haven't installed the new tune, which I will do tomorrow, but I can already tell its a completely different world. It's gonna make drivin the car a lot more fun, sounds like raw unleashes horsepower! I totally recommend buying these as one of your first upgrades. They're inexpensive and a lotta bark for your buck!
