  • Quick answer is yes... If you're lucky.. I could never get mine to seal so we would up cutting off the ball and socket joint and using a cantleak exhaust clamp. Ever since it has been great. My current setup is bbk cat deletes, bbk after cat x pipe, stock over axle pipes with resonators deleted, and gt500 mufflers. By far this is the best sound combo I have come across. Just remember your car will throw a code without cats if not tuned correctly

  • They can work but they do not make a great connection. You will most likely be trying to fix them more than once.

    This product does not fit the factory h pipe and is in severe need of redisign. The 2 3/4" ball is not made to fit in the 2 1/2" socket correctly. You have to over tighten the clamp and even then it will not seal without using some additional sealant. I never did get mine to seal completely but got the leak to be barely noticable but at the expence of a day and a half of putting them in and taking them out repeatedly. Ordered 12-15-12

    Great upgrade for exhaust flow.

    Using the high temp copper sealant recommended for installation, I had no problem getting a good seal with the factory clamp. Noticeable increase in power and sound. May be a bit loud for street applications. My Boss is a dedicated track car and I'm getting decibel readings of 90-93 with these cat delete pipes installed. Prior to installation my readings were 87-88. So expect about a 3 decibel increase in sound. I installed these on jacks without a lift. Install took about 2 hours. Hardest part was getting one of the passenger side cat bolts removed since it needs to be accessed through the engine compartment above. Had to use a 1/2" ratchet with two 18" extensions to get to the bolt. The other bolts can be removed from underneath. As long as you don't need to pass emissions and plan on using short headers, I recommend this upgrade.

    great for the price

    These cat delete pipes are great. i use them for a full straight pipe exhaust and it sounds amazing. at first it was hard to install because after you put them on they leak. They leak A LOT. but as soon as i got them welded on i had no regrets. One thing you should know about them is that your check engine light will turn on in your dash.Even though it does have the hole to put in the o2 sensors they detect the as if the catalytic is running below efficiency. Just tune your car and it will go away. GREAT PRODUCT!!

    Do not buy!!

    The ball connection is too big for the clamps. I am using a 3" flowmaster cat back, and it still doesn't work without leaking. Now my 2013 GT is sitting in my garage on jackstands until I can figure out how to make it stop leaking. Already broke two clamps trying to over tighten to fix the leaks. I may just put the cats back on.

    delete pipe

    The pipes welded nice. They were easier to put in than to take the old cats off. You will reuse the old gaskets so if you do not like this idea buy replacement ones from ford. Overall nice product if you want to stick with shorty headers.

    ok item--fit not bad, price not bad

    Took some working to get them to seal with my BBK X pipe. Tone was raspy and chevy truck like before my tune and obviously the check engine light will be on before a tune. after a tune the note is nice and smooth. hardest part In getting these on is the passenger side top nut you need muscle, a super long extension and a swivel socket. pretty easy to install and could do in an hour or less, on the garage floor none the less since I've done it once .

    Its ok...

    U might as well buy Longtube headers instead cause the stock clamps don't work on these cat deletes. So u gotta weld em on and my h pipe was destroyed before the stock clamps gave out and found out my stock clamps were useless.

    Great Sound, Poor Fit

    I bought these because they were cheap and my future is still unclear with what direction I want to head with performance. I have the Flowmaster American Thunder axle back and it goes great with the deletes. It sounds great. The only problem is that they leak and the shop couldn't stop it all the way. It is not horrible, but it is a bummer getting something put on your car that doesn't work right. Overall though, I am happy with this product.

    Pretty Awesome!!

    So I read the reviews on the cat nuts being a pain getting off. So a couple days before the install I started PB blasting the 4 nuts on the cats. Install day came and the two outer bolts were easily removed by my 1/2 drive Snap On impact with a couple of extensions. The other two bolts were removed with a little muscle on the wrench. I have the BBK X as well and used the copper gasket maker during install so I didn't have to go back under for leaks. Everything installed within an hour an no leaks. Started it up and it was super loud. I had the Hearthrob axleback on my car and it was going to be louder than I could bear. I had also ordered some GT500 axlebacks just in case. I threw them on and I feel it is a perfect note. No drone and calm while cruising but when you open up it sounds amazing plus the car feels stronger. Very good purchase.
