Product Description

Dual Exhaust For Your V6!
This 2005-2009 Mustang V6 dual exhaust conversion kit is a great way to add the aggressive looks of the S197 GT to your 4.0L Mustang. This kit includes an off road x pipe and cat back system to replace your stock exhaust from the midpipe back. With 3.5" polished tips, you can get your V6 Mustang looking better than most GTs!

More Horsepower & Performance!
This dual exhaust conversion not only looks great, it gives your 4.0L Mustang great performance! Replacing your catted midpipe and restrictive exhaust with an offroad x pipe, 2.5" catback system, and high flow mufflers allows for more exhaust flow giving you a nice increase in horsepower and torque. The included off road x-pipe does not have catalytic converters, allowing your exhaust to flow more freely.

High Quality Construction!
Dynomax is a leader in the industry when it comes to bringing consumers high quality exhaust components. This 2005-2009 Mustang V6 dual exhaust kit is no different. It features an aluminized steel 2.25" x-pipe, 2.5" catback, and 3.5" stainless steel tips for a durable construction that will last a lifetime.

Product came quality packed and all parts were included, so it wasn't difficult to install it (maybe a template for driver's side bumper cut should be included). Fitment isn't the best, as passenger's side muffler comes too high, so I needed to cut bumper on that side too (I tried to rotate x pipe or tail pipe, but it didn't help... muffler's holder should be a little bit longer and it would fit perfectly).

I didn't notice much performance gain, but I guess it should be noticeable when driving with high rpms.
All in all... dual exhaust looks great. It's like comparing day and night, when you look at stock exhaust and dual exhaust. 3.5" tips look great... in my opinion better than 4'' tips.
Sound of this dual exhaust is deeper than the stock one, but not too loud... exactly what I was looking for.

Yes, I would recommend this item to a friend!
