Product Description

BBK Catted X-Pipe
Stock exhausts generally strangle high-performance engines, but BBK has the answer for Mustang owners. BBK Performance X pipes have been the number one performance brand that Ford Mustang enthusiasts have enjoyed for years. Their Extractor series X-Chamber mid-pipes benefit from the company's die-stamped X-Chamber crossover, and can give you 12 to 25 more ponies right out of the box.

BBK Quality
1996-98 BBK direct replacement X-pipes feature 2.5” diameter CNC mandrel bent aluminized tubing and BBK's unique die stamped performance Xtracter center X section to ensure maximum flow and horsepower. OEM - original O2 Sensor locations and factory style die-stamped flanges ensure a perfect fit and BBK In-house dyno-testing has shown solid gains of 12-20 horsepower depending on application. All BBK full length X pipes are designed as direct bolt on to factory headers or any aftermarket shorty headers as well as of course BBK shorty headers.

Image uploaded by James Got this catted X-pipe for my 98 GT early this season (had OEM & it was damaged & hanging too low--nice & loud though!) The fit & finish on this X-pipe is fantastic. I've been buying BBK parts since my 1st 1990 LX 5.0L--Quality doesn't disappoint. No clearance issues, nice & tight w/ frame (my GT is 1.5" lower than OE). Exhaust is a bit quieter (it was actually only partially connected?!) Most noticeable is the power increase. Mated this with Flowmaster American Thunder and picked up a much-improved seat-of-the-pants feel, as well as a nice growl. Amazingly civil at idle, nice sound above 3000RPM--how loud depends on how high your RPMs. Highly recommended to stay emissions legal.

Yes, I would recommend this item to a friend!

This BBK catted xpipe paired with some BBK shorty headers & SLP1 exhaust sounds amazing! Nice deep clean tone. At first I went with the BBK O/R xpipe and it was too loud / raspy for my taste surprisingly. This gave my stang the sound i was looking for! install was easy for both xpipes when adjusted correctly. If your running BBK shorty headers and SLP1 exhaust I highly recommend getting this catted xpipe, you will love it!

5 Stars   Exceptional fit + nice sound
By on 9/24/2015
Image uploaded by G James F. Quality part from BBK (have had BBK parts on 7 other cars) one nice thing: tight fit up against the underside of my 98 GT, which is 1.5" lower than factory. Never any clearance issues. X-pipe makes great power: noticeable difference from OEM H-pipe. Nice sound: loud when you want it to be (4K rpm+) and quiet enough around town. Having had cars with off-road H- and X-pipes, I'm over having a super-loud car. It gets old. Like the catalytic converters too: car runs strong, no CELs. *Note: mated with Flowmaster 2.5" American Thunder kit.

Yes, I would recommend this item to a friend!
