Amazing. No other words describe it.

These new cat deletes will have your jaw dropping!!! Installation was a hassle though! Not the installation itself, but the removal of the cats was horrible. Be ready to have a a gun with enough torque

Kooks? do these fit with the kooks 1 7/8 longtube headers?

Question Resolved
Good Question (0) (0)
  • Alex, no, they are made to bolt up to either the factory exhaust manifold or "shorty" headers and span the difference in length that the catalytic converters provided. The kooks long tube headers are longer and should bolt directly to the H or X pipe. Keep in mind that if you go with kooks LTH's, the company states that their headers will only bolt up to their X pipe or H pipe. Mixing aftermarket exhaust components from different companies might result in fitment issues. Hope this helps! Mitch

    Very easy to install after removing original cats

    The factory cats were hard to remove due to the bolts being so tight other then that the pypes delete pieces lined right up

    If you want added power, and sound, this is for you.

    I bought this paired with the Pypes X Pipe and Pypes catback, and everything together made my Mustang a completely different car. It made the car much louder than stock, and paired with a tune, I definitely feel a power difference. Though, all of these together will make your car extremely loud. So if you live in an area where the cops care about how loud your car is, I probably wouldn't recommend this. I, on the other hand, haven't had a cop look at me or have had any issues with the sound. The sound, in my opinion, is awesome, and makes me smile every time I start my car up. If you want more power, and a louder car, I definitely recommend getting this product, paired with the catback and x pipe. You won't regret it!

    These new cat deletes will have your jaw dropping!!! Installation was a hassle though! Not the installation itself, but the removal of the cats was horrible. Be ready to have a a gun with enough torque to get those bolts off! But other than that, figment is PERFECT. No leaks or odd noises. Just that MONSTER noise it gives my '14 5.0. I'm running these cat deletes with factory h-pipe, resonator delete and a flowmaster outlaw axleback. My car is WAY too loud though so I'm thinking to going down to maybe american thunder by flowmaster. Overall, these cat delete are well worth your money.

    The Sound O The Sound!!!

    The sound, what can I say but WOW!! If you like turning heads as you drive by then this is exactly what you need. Ove-corse you get a weight reduction of approximately 15-20lbs for taking those ridiculous cats off. And sure the additional 20hp is a given. But that sound tho... I have a borla x pipe and flowmaster american thunder axleback exhaust, and that combo is music to my ears.. Quite difficult to install due to the position of the bolts, especially the one that can only be accessed threw the passenger side of the engine. So make sure you have all the proper equipment for the job if you intend to do it yourself. Took me an afternoon because i did it alone and by hand. But O man was it worth it once you turn that baby on.

    They don't fit!!

    Needless to say I was excited to get the Pypes cat deletes installed today at my local muffler shop. Now, for the bad news, these cat deletes do not bolt up to my Borla X-pipe. Im not sure why considering the X-pipe inlet is the same as the factory H-pipe. These deletes were about an inch off on one side and 1/2 inch of on the other. A simple $50 job has turned into a $300 dollar job after the muffler shop cut the deletes up and fabricated some new pieces to make them fit!! Poor fabrication from the factory in my opinion.

    not so good fit, but sound is good

    Installed on a stock factory exhaust. The sound is good. The installation was not so good. I had it installed by one of the best muffler shop in Miami and it took them 3 hours to get the leak out and to get it aligned. $270 labor charge for that. This was also shipped with missing bolt. I ended up buying another one and replacing all the washers and nuts with stainless

    Pypes Off-Road Cat Delete Pipes

    Wow, what a difference in the sound. These are not for the faint-at-heart or anyone who lives where the local police strictly enforce a noise ordinance. These are fairly easy to install and sound GREAT in my opinion!!! The sweet combination of these matched with an SLP stainless axle-back including the 4 inch tips is just awesome. Thank you American Muscle.

    Good fit

    These fit right up with stock manifold. I had a shop install them along with an H pipe. Both of these items and a pair of GT500 mufflers and my car sounds mean!
