Looking for a reasonable exhaust upgrade on this m56x from the end of manifold to muffler s. Any one have a recommendation
The Infiniti M56x, with its powerful 5.6L V8 engine, is a fantastic platform for an exhaust upgrade. The engine already sounds great, and a proper exhaust system will really let it breathe and open up its sound.
Since you're looking for a reasonable upgrade from the manifold to the muffler, you're looking for what's commonly called a "cat-back" exhaust system, and here are a few recommendations to consider:
- Stillen is a company that has been making high-performance parts for Nissan and Infiniti vehicles for a long time. They have a reputation for making well-engineered parts that are designed to fit perfectly and sound great. A Stillen cat-back system for the M56x is a very popular choice. It will give you a deeper, more aggressive tone without a lot of the high-pitched raspiness you can sometimes get from other exhausts. It's a bit more expensive, but the quality and fitment are excellent.
- MagnaFlow is a very well-known and reputable exhaust company. They make a quality cat-back system for the M56x that is generally more affordable than some of the more niche brands. It will give you a nice, deep rumble that is a little louder than stock but not over the top. It's a great choice if you're looking for a good balance between performance, sound, and price.
- Custom Exhaust Shop: This is another excellent option for a "reasonable" upgrade. You can take your car to a local custom exhaust shop and have them build a system for you. You can have them install high-flow catalytic converters, a less restrictive mid-pipe, and a set of performance mufflers. This gives you the flexibility to choose exactly how loud you want the car to be and you can often get a quality result for a lower price than a pre-made kit.
A few more tips to keep in mind:
- Sound: Listen to sound clips on YouTube to get a feel for what you like. What one person considers "aggressive" another might consider "too loud."
- Catalytic Converters: If you're looking for a big performance gain, you might want to consider replacing the factory catalytic converters with high-flow catalytic converters. This will increase exhaust flow, but can be a bit more expensive and may or may not be street legal in your area.
- Resonators: Many exhaust systems come with resonators. If you want a louder exhaust, you can remove the resonators, but be warned that this can cause the exhaust to have a "drone" at certain RPMs.
Before you buy a system, I would recommend checking some Infiniti forums to see what other owners have done and what their experience has been with specific brands and models. Good luck with your upgrade!
