How to Measure Exhaust Backpressure for Smarter Exhaust Upgrades
So I've talked before about how you measure intake restriction and how you can actually find the source of restriction by using a differential pressure meter. However, while I've alluded to the fact that you can also do something similar for exhaust back pressure, I haven't done anything about it until now.
Today I want to share with you how you can analyze an existing (or aftermarket) exhaust system using a very inexpensive gauge, some tubing, a spark plug defouler, some jb weld and a fitting from your local home hardware store. It's like tuner MacGyver, but trust me, it works great.
The grand total of the project might run as much as $40-60 or so but you probably have most of what you need lying around.
Most enthusiasts know that reducing backpressure in the exhaust system will typically yield a performance gain. However, there is much speculation about what exactly makes a big difference and what does not. Sure, a bigger pipe will almost always reduce backpressure as will a higher flow muffler with either a straight through or significantly less baffled design.

What’s So Wrong With Nitrous?
Nitrous, or Nitrous Oxide is a power adder that provides incredible "Bang for the Buck" but for a number of reasons that we'll explore today, almost never gets used, and that's a shame because there's really no better way to get a reasonable boost in power for peanuts.
Nitrous has a bad reputation for blowing up engines and is often even called "cheating." Additionally, it gets a bad rap for not being "always available" and for needing refills to keep the power going.
All of these rumors have some basis in fact but as with almost anything, when used correctly, the benefits of nitrous are HUGE, especially for the target audience of this site: daily driven performance enthusiasts.

Modifications that Work (Part II): Engine
Continuing from part I, today I have a few more of the ways that you can increase horsepower in your car without being subject to the gimmick tax. In other words, these are the tried and true methods that work every time. If it's not on this list (or the list in Part I), it probably isn't a great investment of hard earned dollars.
Fitting a supercharger or turbocharger will always net a huge improvement in power production. Truthfully, of all modifications, this is the only one that can take a stock engineed car to another world of performance. While all motor modifications can net a healthy 10-20% gain over factory in a street car, turbocharger applications and superchargers as well both start well over 30% and climb to 100-200% with minimal effort.
