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!

Tune? How much would a tune help out fter replacing the cats with these deletes?

  • A tune is a must, it all works in harmony. And your check engine light will stay on w/out one.

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

Alex3209

  • I do not believe it would work. The flange is different. You probably want to stick with the same manufacturer.

    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 cat delete

    Nice fit except the driver side one had the bung for the O2 sensor aiming slightly down. It is lower than anything else under the car and could get hit if going over a speed bump. No big deal though if you think about it. That O2 sensor is for after the cat. Since the cat is now gone the sensor is not needed. Just put the plug in the pipe and delete the sensor in your tune. The exhaust tone is nothing short of beautiful with the stock mufflers. I went to the hardware store and picked up some grade 8 bolts and it was much easier to put together than take apart, because you can put the nut on the side you can get to easier. Enjoy

    Cat deletes

    If you want to turn the volume up to 11, these are what you need! By far the hardest part about installing these is taking the stock cats off. As everyone else has said, accessing the top passenger side bolt through the engine is an option, but you could also use an open ended crowfoot wrench and get it from under the car (which is how I did it). These will give your mustang a more raw aural experience, but might be too much depending on your current mufflers. Definitely not for everyone. Feels and sounds like it pulls harder everywhere.

    As others have said, it took longer to get the cat conv. off than to put these pipes in. Made my car too loud, like obnoxiously loud, esp. with the Roush axle backs I have. But I made a miniature glasspack insert to slide in each pipe and it sounds great now.

    AMAZING SOUND

    Have borla s types and wanted some more grumble... I definitely got it with these car sounds so angry now!! as far as the install goes in order to make the leak that some people seem to be talking about go away all you need to do I unbolt the h pipe and slide forward slightly then they go perfect snug no leaks.
