what about the check engine light? It will turn on with this product?

  • Yes, the check engine light will turn on as you will be removing your catalytic converters, A simple custom tune would do the trick in getting that light turned off.

  • 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

    Not as loud as I thought

    The pipes showed up to my house in 2 days which is awesome. The header bolts are a nightmare like everyone said. Getting the old cats off took up most of the time. I used the copper sealant and had a minor leak at the factory h-pipe. I rotated the clamps and it went away. I read a lot of reviews so I knew what I was getting into work wise but a lot of people said it made their car super loud. Maybe it's because I had a fully straight piped 4.6 but it's not as loud as anticipated. I have flow master axel backs and these cat deletes and it still has a nice low growl but not the volume I was looking for. Going to try an h pipe next but overall pretty happy. Need a tuner with these pipes or you'll throw a CEL. All in all very worth while and happy with the outcome.

    Amazing noise and power adder.

    Along with these cat deletes I have installed pypes pype bomb muffler deletes. Before the cat deletes I was fairly loud, now when I drive down the road everybodys head is lashing in my direction. The car absolutely screams.. I noticed a small difference in power and a smoother shift but I have not had my car tuned yet. These pipes work great on the factory tune and were installed in about 35 minutes for 120$. If your looking for a power adder, cat deletes are a great way to go, and if you want your car to be so loud people hate you and look at you with envy, buy these cat deletes!! You wont regret it. Also, if your worried about drone, dont worry, with my windows up my 2011 GT/CS is relatively quiet in the cabin.

    Ok, overall

    The ball and socket isn't the right size, so it's a PITA to get these to seal up. Save yourself the hassle and get 2 ea. 3.5 inch stainless band style clamps at o'reilly for $24 before you install. Break the ball and socket clamp stays with a sturdy flat tip off and remove them from your stick H-pipe and clamp them in place and save yourself the hassle. No weld required.

    Cat delete pipes

    Like everyone else has said after getting the cats off these go on fairly easy but it's almost impossible to get them to seal the balls are to big for stock clamps. Right side sealed okay but left side but dented some on ball in and took for ever to get sealed. BBK really needs to correct this problem because it sounds and runs great without leaks. Just hope it lasts !!!!

    Not worth your time or money

    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!!

    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.

    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.

    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.

    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 .

    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.

    Install was easy once the old bolts were taken off stock system. The sounds is richer and deeper now. I highly recommend this item if you need more flow leaving the engine due to the restrictions of the cats.

    good fit, really really loud.

    I had no problems with fitment, i purchased 2 sets of Pypes before this and they were both terrible, these were right the first time, they matched right up to the factory H and my Corsa X-Pipe, i tried both just to make sure. I have corsa extremes axlebacks and stock resonators on and its really loud, it backfires alot, but it sounds mean, just be prepared because you are going to attract a lot of attention. Install took about 90 minutes, but i had already dont this 2 weeks before so i knew what to do.
