More Power and Torque. The SLP X-Pipe uses free-flowing mandrel-bent tubing with a genuine X style crossover and high-flow catalytic converters to provide a significant increase in horsepower and torque over the restrictive stock factory catted pipes.

Race Car Growl. This free flowing SLP x-pipe for the 1999 to 2004 Mustang's not only increases power, but it also adds a raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

Upgradable Modular Design. SLP's exclusive three-piece modular design makes it possible to easily upgrade to SLP's Long-Tube Headers without the need of purchasing a brand new X-pipe by just removing the down pipes. This unique modular design also makes it easy to install this X-pipe on your Mustang with just basic hand tools.

Quality Stainless Steel Construction. Constructed entirely from 2.5" mandrel bent stainless steel tubing for improved exhaust flow, this SLP mid-pipe features a true "X" crossover, not a poor-flowing clam shell imitation that other companies use. The included SLP High flow cats far out perform the restrictive stock factory catalytic converters to increase rear wheel horsepower and torque.

Application. This Catted X-pipe from SLP is designed to be a direct bolt-on for the 1999-2004 GT, 2001 Bullitt, 2003-2004 Mach 1, and 1999-2004 SVT Cobra Mustangs with either aftermarket short tube headers or the stock factory manifolds and a dual catback exhaust installed.

Technical note: 2004 SOHC and DOHC applications require the use of 18" O2 sensor plug-in extender wires.

    I started off with LM1's and stok H, was getting 25.5 mpg on the highway... put this X w/cats on and (Although the throttle response and power was better)my highway mileage went down to 22-23 ish... if it's performance with mileage for a daily driver that you are looking for you're gonna need a tune if its more than a cat back that you wanna do, get a tuner to make it work for you the whole way, not just accidental horsepower. This ia a good kit, nice build quality and fitment, but trust me, the tune is necessary to make the difference from better to best.

    Put these on with an SLP LM-1 cat-back and its definitely worth the money. The highflow cats improve flow greatly as well as a deeper tone. The greater opening in the cross over section is also a great power gain. Must get this if you want to really do your exhaust right.

    Checked all the products offered for mid-pipes, After rechecking each one for their reviews I decided to go with SLP. Bassani had the cat cutouts , The price for the difference was not me. I made the right choice, This SLP with ceramic cats sound very good from idle up Flowmasters Delta Flow 40s behind them provide the tone, throttle response improved Installation was 1hour 30 minutes perfect fit first time!!! No leaks, Thanks for speedy shipment.
