    Will it fit bbk shorty headers or need to buy the long tube headers?

    • The Pypes The Beast Off-Road Exhaust will fit stock and shorty headers. Long tube headers would require a shorty mid pipe, this one is stock length.

    with this exhaust will it pass emissions in mass without the cats in a 93 gt

    • If your state has adopted CARB regulations or has emission testing then it will not pass You will need to reach out to your local inspection center to find out your local laws regarding off-road exhaust.

    Will this fit 1986 Ford Mustang GT 5.0 5-speed or not? This site is giving me mixed messages. Some places it says 86-93 GT, other places it says 87-93 GT. The check your fitment box says SORRY, THIS WILL NOT FIT THIS MUSTANG. Part number SFM13B says it only fits LX models, yet the check you fitment box on that part number says it fits 1986 GT. So what is the truth? Which one should I buy for 1986 GT?

    • This will indeed fit with the 86 GT models.

      Well made of quality materials

      Took a little time to get everything hung correctly, but we eventually got it without any cutting. Seems like the driver side down pipe from the exhaust manifold is a bit long or not bent correctly. It hangs lower than the passenger side and is the lowest point on the entire system.

      Sounds great.

      The exhaust is high quality and sounds great. Just not sure why it hangs so low in the front.

      Not too shabby

      Put these pipes on my 93 gt. Love the sound. Kinda works out great because if I want to, I can be quiet. But if I want to unleash the beast, these pipes are capable of making the sound I wanted.

      Awesome Power and Sound

      I had the exhaust system installed by a mechanic. I do not have a lift only ramps and there was not enough room under the car to do it myself. I am very pleased with the outcome, sounds better than described. I can say my 1991 GT Convertable now sounds like my brother's 1967 Shelby!

      Close but not perfect

      The beast by volume for sure, but as for direct bolt on, can also entail the beast monicker . Twisting and turning every which way might not get you to perfect, especially if your down pipe isn't cut with a 90 degree off the main tailpipe...which mine isn't . Voluminous and aggressive growl makes for quite an awesome combo but as for look make sure you do a mock up before you install it. Or else yours might have been made Monday morning or Friday evening like mine. In the end the sound , far and away unique, unfortunately mine ended up looking like Quasimodo and sounding like Sinatra

      great product.

      this exhaust combo was a decent buy. A ittle bit of cutting and welding but i eventually got it to work. sound is pretty good as well. exhaust gives off bit of a raspy noise with out the cats. Thinking im going to switch the mufflers to flowmaster. but all in all. good buy.

      This product is great, fit really well with the shorty headers. Rumble is great but for those of you who live in a small community, it's LOUD... Makes my mustang sound mean, especially with the BBK cold air added now as well.

      This exhaust sounds great, it has a nice deep throaty sound that roars when you get on it. The install was fairly easy and it looks great too. I recommend this product. The sound it produces stands out from other exhausts. love it

      this system sounds great, very comparable to any major brand, and you can feel and hear the difference when you romp it.
