Cadillac Exhaust Systems are a very subjective category, as the best exhaust for you is the one that sounds the best to -your- ears. Much the same way as your favorite craft beer may not be the same one your buddy prefers, it's in the eyes and ears of the beholder. That's why we produce special videos that let you HEAR the SOUND of the exhausts we offer. We offer many aftermarket parts and accessories as well, since we're not like your average exhaust and muffler shop. Choosing an exhaust for your vehicle isn't as straightforward as it was back in the Muscle-Car days - Our Modification Experts can recommend an exhaust that suits the character you want your exhaust to exude.

Since we've built many popular enthusiast vehicles ourselves, we've got the experience to let you know about issues you may encounter and offer advice you'll only get from another enthusiast. In fact, one of the company owners drives a modified CTS-V himself.

What types of Exhaust Systems are available for my Cadillac?

Different types of Exhausts for a Cadillaclower view of an isntalled ExhaustCadillac Exhausts

The design of an exhaust system can vary depending on which parts of an exhaust system you want to replace. Systems can be either bolt on exhaust kits or weld-in, depending on style and manufacturer. Exhaust systems are typically offered as header/downpipe-back, cat-back or axle-back, which refer to how much of the exhaust system is included.

Stainless Works full Exhaust system

Typically, cat-back or header back is best for performance and sound improvements, whereas Axle-Back is more ideal if you are simply after a better exhaust tone. While less effective, because there is much less of the exhaust system replaced, axle-back setups are usually less expensive and make less of an alteration to the vehicle. We offer exhaust systems for Cadillac from Korkar Performance Engineering, Stainless Works, Borla, Magnaflow and Flowmaster.

Axle-Back Exhaust

Axle Back Exhaust

This is the best option for those on a tighter budget or mainly after sound or aesthetics. This type of system usually only replaces the mufflers aft of the rear axle, hence "axle-back". Many manufacturers offer Axle-Back options including but not limited to: Korkar Performance Engineering (KPE), Stainless Works, Billy Boat, Borla and Magnaflow.

Cat-Back Exhaust

Cat Back Exhaust Cat Back Exhaust

This is the most common choice for upgrading your exhaust system. This type of exhaust system includes different mufflers like an Axle-Back system but also includes larger diameter exhaust tubing and spans the length of the exhaust system aft of the catalytic converters, hence the term "Cat-Back". This type of exhaust system is more expensive, but offers tangible performance gains as well as an improvement in sound and aesthetics. An even wider variety of Cat-Back systems are available from the finest names in exhaust, including: Korkar Performance Engineering (KPE), Billy Boat,Stainless Works, Borla, Corsa and Magnaflow.

Headers (aka Exhaust Manifolds)

Headers or manifolds

Headers, as they are commonly called, are the exhaust manifolds - most commonly, "headers" refers to a high performance exhaust manifold. They can be manufactured in cast iron, cast aluminum, 304 Stainless Steel or even exotic materials like Formula-One grade Inconel 625 alloy. In the case of a naturally aspirated or supercharged (non-turbo) vehicle, the exhaust manifolds are connected to the exhaust ports on the Cylinder Head of the engine and channels exhaust gases out of the engine and directs them into the exhaust pipe at the outlet of the headers. These offer performance increases by smoothing out the flow of exhaust gas out of the engine, allowing the engine to operate more efficiently and thereby make more power. the enhanced design can remove or relocate catalytic converters integrated into the OEM manifolds in some applications and some are engineered for precise equal-length manifold runners ("equal length headers") for even greater gains and efficiency. Supercharged engines in particular, will respond more to a set of headers than a naturally aspirated car. There are two main types of "headers".

-Shorty Headers
Shorty headers, as their name implies, are short and only span the distance between the engine cylinder head and the catalytic converter (or turbocharger, in the case of a turbo car). This is the most common style of header.

-Longtube Headers

long tube headers

Used primarily on naturally aspirated or supercharged cars, long tube headers eschew the catalytic converters complete and use long exhaust runners to create both an incredible, unique sound as well as deliver significant power changes. These are more expensive, and also much trickier to install than shorty headers. Long Tube headers are especially popular on Domestic Muscle V8 applications and are an especially good choice for the Cadillac CTS-V. While it may only be the opinion of the author, a CTS-V sounds like the thunderous roar of the gods of old when fitted with long tubes. We offer Long Tube Headers from Stainless Works, Kooks, and other fine exhaust manufacturers.


KPE Downpipes

The downpipe is a part of the exhaust system only on turbocharged vehicles. The downpipe is the part of the exhaust system that connects from the turbocharger's outlet to the rest of the exhaust system. Many OEM downpipes feature integral catalytic converters, which are often highly restrictive. Performance downpipes streamline the flow of exhaust gases out of the turbo for better throttle response, faster spool-up and more power and often either omit the catalytic converter or replace it with a high performance unit.

A Cadillac ATS 2.0T Downpipe
from Korkar Performance Engineering, for instance, is a re-engineered to eliminate restrictions in the OEM system for enhanced flow. This results in much faster turbocharger spool-up times (less lag), enhanced exhaust sound and significantly improved power. Generally speaking, most downpipes will yield similar results. A downpipe is a great bang-for-the-buck modification for most turbocharged vehicles and really unlock the potential of your turbocharged motor. A multitude of manufacturers offer Catted and Catless Downpipes for a wide variety of turbocharged models.

What will my new exhaust sound like?

modbargains is changing the way you buy exhaust - we offer a selection of the finest brands in the exhaust performance industry. Our cutting edge media team is constantly uploading videos of installed exhaust systems so that you can really HEAR the sound of that particular exhaust installed on your model, giving you comfort that you'll like the sound you get as well. In addition SEE the fitment of the exhaust and visualize how it'll look on your car, because nothing ruins an otherwise great exhaust like poor fitment.


We hope this has helped you better understand some of the types of Exhaust Systems that are available for your Cadillac on the automotive aftermarket.
