Product Description

Improved Exhaust Flow
A great way to get more exhaust flow for improved horsepower and torque in your 2011-2014 Mustang is installing a set of Pypes cat delete pipes. These pipes install onto your exhaust system, deleting the power robbing factory catalytic converters. This allows more exhaust to exit quicker improving performance and giving your exhaust a throaty exhaust tone.

High Quality Construction
With a high quality, 409 stainless steel construction, these 2.5" mandrel bent pipes are built to last the lifetime of your vehicle. Pre-installed oxygen sensor bungs make installation a breeze when installing with O2 extensions!

It is recommended that you buy a custom tune to turn off the rear O2 sensors to prevent a check engine light.

3 Stars   Horrible fit.... Wow unbelievable

Bought this item and I got wat I expected. Hit or miss with pypes! The outlet was wayyyyy to big for stock hpipe. End up taking to a shop to weld. Great sound after I get rid of leak and noticeable gains Imo. If I could do it all over I'd save the money and get LT headers but I couldn't wait. Pypes delete with gt500 are good enough for now. Thx Lmr for speedy shipment.

Yes, I would recommend this item to a friend!

The ball on the cat delete where it connects to the factory exhaust is a solid 1/3"-1/2" larger than the ball on the factory cat. Ended up just getting the exhaust shop to weld the pipes together. Don't recommend this product, but I have a Boss 302 and didn't want to lose my side pipes, so I wasn't left with much of an option.
