        Great Cat System!

        You just can't beat BBK exhaust products. I had a new BBK X-pipe on along with Flowmaster American Thunder cat back exhaust system on my 88 GT with a 347. It sounded great if I was still a young man, but being 59 years young, my ears just didn't like it as much. It was too loud. So I bought the BBK X-pipe with cats from American Muscle. It toned the exhaust down to a great sound for the street. And of course American Muscle got it right out to me as always. American Muscle is a great place to do business with. Thanks,

        Great Product!

        The piping didn't seem to line up exactly at first but the two piece design made it easy to correct that. Instant throttle response, and an added increase in power. Great product, sounds great, and passed emissions easily!

        Easy way to increase horsepower

        These hi-flow cats sure made a difference in the power increase on my Mustang! I had no experience in this type of work and worried that it wouldn't fit right,but everything went in without a hitch...thanks American Muscle! Sergio M

        BBK Catted X-Pipe on 91 Foxbody LX 5.0 Mustang

        This xpipe is high quality stainless steel. It sounds very good. I am able to pass emissions in PA. I feel some more throttle response over factory. I have it linked up to BBK shorty headers and flowmaster stainless 44 series cat back exhaust. The exhaust is throaty when your at WOT at idle it has a nice rumble that is not obnoxious. The price is great and I think its definitely a good high performance option. Thanks

        BBK X PIPE

        Fast deliver, quick and easily installed. I like the new 3 piece design. Really comes in handy when you are trying to install it by yourself in your garage on jack stands. Plus, I like that everything needed to install is in the box. Thanks American Muscle!

      Will this bbk x pipe work with shorty headers ?

      • This BBK Catted X-Pipe will work with shorty headers meaning you will not have to cut either pipe.

      How in the world do I find out, if it is California compliant without adding it to my cart? I am tired of adding catted X pipe, only to find out that it is not California legal!

      • The BBK Catted X-Pipe is not legal in California. All California legal headers, mid pipes, and cold air intakes will list the CARB EO number, which is required to pass smog in California, in the product features.
