Our simple male minds always seem to dump into a "bigger is better" mentality. For many things this sort of thinking make sense. But for exhaust diameter, the logic breaks down.

A bigger exhaust CAN flow more air than a smaller one. But how much your engine CAN flow is a different amount of air. The goal of the exhaust is to flow the air the engine is capable of processing in the most efficient way it can. After tuning, improving airflow on the inlet, raising boost, and other upgrades the need for a larger exhaust is clear. The engine can support more airflow, so the exhaust needs to support it as well.

But there needs to be a realistic view of what the engine is capable of doing before the size of the exhaust can really be determined. The point is, the exhaust size is a tunable factor just like spring rates, the ride height and the damper firmness. More isn't always better!

When installing lowering springs, coilovers, or any other product that lowers the car, the conventional wisdom is that you should wait and drive the car around for a while for the car to completely "settle." In reality, the springs won't, or should not, change height over time. The car will need to be rolled to neutralize the tire position before the height of the car can me measured, but this has nothing to do with the springs! It happens every single time the car is lifted off the ground.

When you buy almost any product these days you expect there to be some form of a warranty or guarantee to back up your purchase in case it fails. The thing is, with aftermarket auto parts, making good on these niche parts warranties is harder than you want it to be. First of all, any kind of warranty has to exist. And when it does, there are an array of exclusions that probably preclude a part's eligibility for coverage.

If you buy quality parts, though, you'll find that reliable warranty coverage does exist in the performance aftermarket parts industry. That doesn't mean warranty claims are a complete lock. If you are going to claim a parts warranty, be prepared to give up some information. Sometimes a lot of information, to help validate the issue.

This podcast is about being patient through the process of engaging with manufacturers for warranty support and what to expect. Expect to be annoyed, but have faith and stick with it. The better brands always make good by supporting their products.
