Frequently Asked Questions

Are Pypes systems and components covered by a warranty?

All Pypes mufflers and systems have a limited lifetime warranty. All muffler delete systems are sold as is only and do not carry warranty.

Do the Pypes systems come ready to install?

Yes & No, All systems are mandrel bent for various body styles but because of different headers, mufflers and options some systems may require cutting pipes to size. Also an occasional “tweaking” of a pipe might be necessary to fit certain models. Please refer to your instructions for more details on your model.

Why doesn't my X-pipe reach my headers?

This is normal. The X-pipe should mount directly below where the tailshaft meets the driveshaft. You will need a straight piece of pipe to attach your collector reducers to the X-pipe front extensions. Exception: Later model Mustang X-pipes are direct bolt on!

Is it true that the X-pipe will interfere with the removal of my transmission?

No. The Crossover fits BEHIND either an auto or manual trans. Transmissions can easily be removed by disconnecting the front of the exhaust from either the manifolds or the headers and letting the system hang down.

Should I base my muffler choice on the highest flow rating?

Not always. In dyno tests higher horsepower cars (400+) almost always benefit from maximum flow. Lower horsepower cars (300-) can actually lose some low end torque and peak horsepower by using maximum flow mufflers. In these cases, choose the Pypes muffler that fits your sound & price needs as your priority.

I have smaller than 2.5" manifolds, can I use your 2.5" exhaust?

Yes! In all cases that have 2.5" downpipes have engineered them to bolt up directly to your existing smaller manifolds without modification.

It seems as though 3" exhaust is the popular choice these days. Is there any disadvantages?

Yes! A stock horsepower car with 3" exhaust can lose noticeable low end torque and affect performance. Also, 3" pipe usually requires increased installation precision because of limited clearance issues. As a general rule, cars with less then 500hp should use 2.5" mandrel bent exhaust. Cars in the 500hp range could potentially benefit by a 3" system but unless you are trying to shave 1/10ths in the quarter mile, 2.5" mandrel bent pipes are still dramatically better than 3" shop bent systems.

What is the advantage to having a ceramic coated exhaust?

Ceramic Coating not only looks great, it also extends the life of your exhaust almost indefinitely. Mostly it’s thermal qualities create significant additional Horsepower.

Do I lose a lot of clearance after installing a 2.5” or 3“ X-pipe system?

Properly installed X-pipes DO NOT interfere with transmissions! Clearance is no different than a non-crossover system of the same size.
