In the never ending quest for lower drag times a car tuner will often times start with removing the restrictive factory exhaust system and decreasing backpressure. A complete exhaust revamp can consist of anything from a header(s) to a cat-back exhaust system. Choosing which one is right for you is a task that must be undertaken with consideration to your local street laws.

Headers: The factory exhaust manifold is usually a bulky cast-iron unit that is designed to deliver low-end torque (provided by the small primaries). While this is desirable for daily-driving, it is not the ideal for performance. Many factors can affect a headers performance but generally the features you should be concerned with are:

  • Primary Width – Wider the primaries the more peak torque (but later in the power band). There is a limit to how big is big enough that varies from engine to engine.
  • 4-1 or 4-2-1 Design. A 4-1 design incorporates all 4 primaries intersecting into the collector whereas the 4-2-1 has the primaries split into twos and then into one. Different designs offer different power bands.
  • Type of steel- No question here, what you want is SS for the highest quality and most corrosive resistant header(s).

Catalytic Converters

While usually pin pointed as the main restriction in an exhaust, nothing can be further from the truth, while true catalytic converters do restrict flow just like anything else in the pathway of the exhaust gases; they do not hinder flow anymore than the muffler. In fact most catalytic converters are less of a restriction than a muffler. I would always opt for a high flow catalytic converter in an emissions state. These have been proven to provide a negligible loss in horsepower while still keeping it road legal.

Exhaust Piping

Becuase of the budget/time that’s put into both R&D and producing a factory auto, the Yoshimura Exhaust tubing is usually a ho hum choice. Just like the stock exhaust manifold, it suffers from too small diameter piping and crushed bends. When replacing the entire exhaust system always look for a mandrel bent system (small exhaust shops cannot offer this service) that is also stainless steel. The mandrel bends are somewhat more important than the overall size of the exhaust.

Picking the diameter is a fairly easy decision and should be followed by a general outline such as this:

  • 2″ Stock- Very Mildly Modified
  • 2.25″ Mildly Modified-Moderate (exhaust,header,cold air intake,tune)
  • 2.5″ Moderately Modified- Built N/A engine (exhaust, header, cold air intake, tune, pistons, rods)
  • 3″ Forced Induction – Turbo or SuperCharged

Mufflers

Look for a straight through design from a respected name. Magnaflow, Flowmaster, Walker, and Thrush are just a few of the better performance muffler outfits. Glasspack mufflers tend to be a good compromise of performance at a lower price.

Be yourself: Road Head

Leadership is all about being yourself and demonstrating personal authenticity rather than learning some formula from a text book.  Aspiring leaders therefore need to be true to themselves; not slavishly following other’s ideas. Role models can be powerful and it doesn’t hurt to model excellence when found; executive coaching is based on this premise.

Real leaders are prepared to reveal their weakness, because they know they are not super-human.  Obviously this doesn’t mean technical weaknesses or functional failings; this would fatally flaw their performance.  Instead, what is meant is that leaders should reveal their personality quirks – maybe they are bad tempered in the morning, are somewhat shy with new people or a little disorganized. Such admissions show they are human and this resonates with others confirming that the leader is a person – not merely a role-holder.

Revealing their true selves, leaders can allow others to know and help them and this makes for better teamwork; followers can also feel better if they’ve got something to complain about. Thus by sharing at least some of their weaknesses, leaders can prevent others from inventing damaging problems.

True leadership is therefore much more than a demonstration of strengths. Real leaders acknowledge their shortcomings and may even make them work for them.

Good leaders always rely on their ability to read situations. They develop a ‘feel’ for an environment, and interpret soft data without having to be told. They know when team morale is patchy or when complacency needs shaking up. There are three levels of situational sensitivity, each of which has its own specific skills.

Effective leaders are continually learning about the motives, attributes and skills of their important subordinates. They get to know their people through formal and, often better, informal contact such as when travelling together.

Effective leaders read their teams. They analyze the compound balance between team members, the tension between the tasks and processes, and how the team builds its competencies.

Finally, they are concerned with defining the cultural characteristics of their organizations and keep their finger on the digital pulse oximeter of the organisation’s climate.

It sounds tongue-in-cheek to say that leaders care for their people. Ever noticed the cynicism in the workforce upon seeing a manager return from a people-skills training course with new concern for others. Effective leaders don’t need a training programme to convince their employees that they really care. They clearly empathize with their people and care intensely about their work.

Genuine concern is difficult because it always involves some personal risk – showing some part of yourself and your most strongly held values can seem quite scary. It may also take some detachment – the ability to stand back, see the whole picture and sometimes take tough decisions. Leadership never was a popularity contest.

Effective leaders use their differences and move on to distinguish themselves through personal qualities such as sincerity, loyalty, creativity, or sheer expertise.

Using these differences is a critical leadership skill. But, as always, there is a danger – too much distance makes it impossible to sense situations properly or to communicate effectively.

situation. Develop “feel ” for the environment, soft and interpret the data without having said. Know when the team's morale, incomplete or when complacency needs shaking. There are three levels of sensitivity of the situation, each has its own abilities.

leaders success are constantly learning the motives, traits and abilities, their subordinate importance. Meeting people through their possession, and often better, as the informal contacts traveling together.
