Although it costs more, titanium can give you a significant weight savings in addition to the horsepower boost. Some catback exhausts are made out of lightweight metals such as titanium. Most vehicles come from the factory pretty quiet in order to comply with noise restrictions and make the car pleasant to most drivers.

If youвЂ™re not going full send, an aftermarket catback exhaust system is a great way to wake up a stock car. Since the catalytic converter is left in place, catback exhaust systems do not require an aftermarket tune. 3) Aftermarket Catback Exhaust SystemДЄ catback exhaust system replaces every exhaust component behind the catalytic converter (hence the name). Doing this wrong could make it sound more like an exhaust leak than a fancy system. Search your make and model on forums to see if there is a common method used to drill a hole that will give a nice sound.ДЇor a more finely tuned exhaust note, you should look into getting an aftermarket catback exhaust system. Many people use a small drill bit to modify their muffler to get a bit of extra sound. If youвЂ™re not ready for a completely unmuffled sound, you might be able to get away with a hole in your muffler. A muffler is the main device used to quiet the exhaust system, so if you donвЂ™t have one, your vehicle will be much louder.ДЄ muffler delete is not an elegant approach, but it does the job. If you have a Sawzall (reciprocating saw) or hacksaw and can get under your car, you can perform this mod. Expect to pay a bit more for a larger vehicle simply due to the cost of materials. If you want to make your truck exhaust louder, most of these options will still apply to you. You need your boost gauge set-up properly to see how it functions.The following are some possible ways to make your exhaust louder with their relative cost. All controlled by the ECU based on a number of parameters. example: Revving the engine will produce not more than maybe 1 psi of boost! But, the instant you let the clutch out and press the go pedal, the Turbo begins doing it's thing. the ECU and N75 do their thing based on load of the engine! It takes load for the Turbo to function. However, at idle, I can hear most VNT 15s whistling! The whistle sound is fairly distinct on my ALH Vanagon as the exhaust system is quite short.Д«ack to the Actuator. I have no idea what it sounds like for a turbo to 'spool-up' as my hearing is not so good. in fact, if you are running 70 mph and let up on the accelerator, the boost will drop to zero! The position of the Actuator stays there at idle. happens in a matter of a few seconds if everything is working fine! The Actuator arm pulls down solid against the set-screw.

The instant you start the engine, vacuum builds, the ECU activates the N75, and the N75 pulls vacuum on the Actuator. I am afraid of damaging the engine by having the turbo spooled up all the way, so i've been driving it around with the actuator disconnected, and it seems to run just fine.

I did notice that the check valve for the vacuum lines is not working, but i dont know how that would cause the N75 valve to open the turbo actuator all the way. I have a boost gauge, but the previous owner hooked it up to a vacuum line so i am not sure exactly how much boost its putting out. Is this supposed to happen? Why is it boosting all the way at idle? I don't know how these are supposed to work, because i've never had a working one.

The turbo now works and spools up and down by applying vacuum to the actuator, but as soon as i hook up the vacuum line to the N75 valve the turbo spools up all the way. I also checked all the vacuum lines to be sure they were correctly routed, and re sealed the injector pump. I rebuilt the turbo, replaced the actuator, cleaned the intake manifold, and replaced the N75 valve. I recently bought a 2002 Jetta and immediately began having an overboost code.ДЄfter some research and troubleshooting I found that the turbo vanes were siezed up, and the actuator was bad. Hello all, I am new to VW, new to diesels, and new to the forum.
