Here are some more information for Dohc Vtec Exhaust:
The first major component of your performance exhaust system is the header. Most Honda Acura come with a crude cast iron log-type manifold stock from the factory. However Honda Acura manifolds are much better than the ones found on a domestic cars but more power can be made with a real tubular header. How much power you make with a header depends also on what is behind the header. If the stock exhaust system includes restrictive muffler design, small diameter exhaust pipes with a lots of wrinkle bends on them the header is not going to have a chance of making a big difference in the performance and horsepower. A good header can be expected to make 3-5 horsepower with the stock exhaust system from the header back. That sounds disappointing but on a engine with numerous modifications the same performance (aftermarket) header can gain you 10 horsepower. Any of the big power adding modifications like nitrous oxide, supercharger virtually require a free flowing exhaust and performance header if you want to take advantage of there power potentials.
Performance headers usually come in 4-2-1 design where each cylinder has its own exhaust pipe than they merge into a pair and each pair of pipes combine into a single pipe. Usually cylinders 4 and 1 are combined and cylinder 2 and 3 make the second pair. The cylinders are combined in such a way because the engine pistons fire 1 and 3 then 2 and 4 and the exhaust of cylinder 4 is going to create a little (from 5 to 15 psi) negative pressure for a cylinder 1 that is going to help to suck out the exhaust gas out of that cylinder.
Installing performance header is quite easy. Most aftermarket headers are design to use all the factory mounting points and brackets. When shopping for a header look for clean welds and thick flange plates for a good seal. The stock gasket should be replaced and it is going to work perfectly fine with your performance header. Make sure to check if the engine in your Honda Acura car is the original or it's an engine swap. Most headers don't have brackets for mounting the factory heat shield but it is pretty sure you will want to show off your new header anyway.
Performance exhaust header can be installed on Prelude, Civic, Rsx, s2000, Integra or any other model Honda Acura car.

2008 Acura Tsx: the Lure
Acura, the luxury brand of Honda Motor Co., offers a new lure in the all-new TSX. The near-premium sports sedan flaunts taut design, razor-sharp reflexes, cutting-edge technology and a long lost of standard luxury features.
The modifications made to the gorgeous sports sedan are aimed at winning over shoppers and enthusiasts. The 2008 TSX continues the exceptional blend of style, performance and efficiency that has helped it attract many new drivers from other players in the sports sedan market.
"The TSX has clearly established itself as a serious player in the sports sedan segment," said Dick Colliver, the executive vice president for sales. "It serves as a critical entry point into the Acura brand for thousands of new luxury customers each year, and delivers in spades on the advanced performance, technology and style of Acura."
The new TSX is powered by an advanced and efficient 2.4-liter DOHC i-VTEC 4-cylinder engine producing 205 horsepower and 164 lb-ft of torque, delivering performance on par with many 6-cylinder powerplants. The computer-controlled i-VTEC "intelligent" intake/exhaust valve actuation system delivers improved performance across a broad powerband.
The TSX engine is also equipped with Drive-By-Wire Throttle technology that helps bolster the car’s performance, efficiency and enhanced driver control. Along with its remarkable horsepower output, the car with manual transmission has an EPA fuel economy rating of 19/28 mpg city/highway. Additionally, the automatic transmission version of the car has a rating of 20/28 mpg.
The 2008 TSX is also equipped with air-assisted fuel injectors, a uniquely positioned under floor catalytic converter, and a high-flow stainless-steel exhaust manifold help the TSX achieve the U.S. EPA's stringent Tier 2-Bin 5 (and CARB LEV-2) exhaust emissions standards.
To offer stability and outstanding stopping power, the new TSX is equipped with large 4-wheel disc brakes with ABS, 17-inch alloy wheels and Michelin all-season high-performance tires mated to Acura belts.
On the outside, the TSX shows off dynamic curves and crisp lines. To boost design cues, the sports sedan is given the signature 5-sided Acura grille, angular side markers and bumper-integrated fog lamps. In the rear, the taillights slope to meet a short, high trunk lid that terminates sharply to help air separate cleanly off the back of the car at speed. Stylish nine-spoke, 17-inch alloy wheels finish the TSX's sporty appearance.
Parts of its safety features like the refined and highly responsive suspension, steering and braking systems, the TSX comes equipped with standard Vehicle Stability Assist™ (VSA®), anti-lock brakes (ABS) and Tire Pressure Monitoring System (TPMS).
In the event of a crash, the car uses multiple advanced safety technologies to help absorb and redirect the energy of the crash. These technologies include dual-stage, dual-threshold driver and front passenger airbags along with side airbags for the driver and front passenger. The passenger side airbag features an Occupant Position Detection System (OPDS) to preclude airbag deployment if a child or small-stature adult leans into the deployment path. What is more, the car is also equipped with side curtain airbags to help protect occupants from head and neck injuries in the event of a significant side impact.
These features, working in conjunction with the vehicle's energy-absorbing body structure, help the car graner a NHTSA 5-star rating in U.S. government's frontal crash test along with a Good rating in the Insurance Institute for Highway Safety's (IIHS) 40mph frontal offset test.
The Acura TSX, a product line built by Honda, was unveiled in April 2003. The car is sold in North America to rival entry-level luxury car flagship such as the Audi A4, BMW 3 Series, Lexus IS, Mercedes-Benz C-Class, Saab 9-3, and the Volvo S40.

Question about TDC camshaft/crankshaft?
Ok, integra gsr engine, dohc, vtec, 4cyclinder
Intake/Exhaust below refer to location of camshaft
- - -
Intake - 0 Degree or 12:Oclock or exactly on top
Exhaust -0 Deg.. or 12:oclock or ex....
-->Result - Piston 1 is at TDC
- - -
Intake - 90 Degree or 3:oclock
Exhaust -90 Deg.. or 3:o..
-->Result - Piston 2 is at TDC
- - -
Intake - 180 Degree or 6:oclock
Exhaust -180 Deg.. or 6:ocl..
-->Result - Piston 3 is at TDC
- - -
Intake - 270 Degree or 9:oclock
Exhaust -270 Deg.. or 9:ocl..
-->Result - Piston 4 is at TDC
Looking at the crankshaft, piston 1&4 move together and piston 2 &3 move together.
a)Is it safe to assume that for every 360 degree rotation of intake camshaft, the crankshaft rotates 720 degrees?
b) When they indicate piston 1 is at TDC, is it just some timing term, or does it refer to the actualy physical location of the piston. If it refers to the location of the piston, is it fully up, ind the middle of the cylinder or fully at the bottom.
