Do you need a turbo for a downpipe?

If your vehicle is equipped with a turbocharger, a downpipe may be part of your solution. The downpipe bolts directly to the turbine housing and helps direct exhaust gases through the rest of the exhaust system. Most factory downpipes will have at least one very restrictive catalytic converter.

Are downpipes only for turbo cars?

A downpipe IS for turbo cars, but for all practical purposes we still call our n/a frontpipes "downpipes".

Is downpipe connected to turbo?

Downpipes are sections of tubing that connect the exhaust side of a turbocharger with the start of the vehicle's exhaust system, allowing spent exhaust gas to exit the engine.

Do I need a tune if I install a downpipe?

Registered. Less backpressure from a less restrictive downpipe = turbo builds boost faster = more air into the engine from the turbo = you absolutely need a new tune to compensate for that.

Is a turbo back a downpipe?

The Cat Back is an exhaust system that contains the catalytic converter, whereas, installing a Turbo Back Exhaust system will include also installing the downpipe that connects everything together.

5 Things you NEED to know BEFORE buying a DOWNPIPE (F30 BMW, WRX, EVO, Supra, and any Turbo Car!)

Is a cat back worth it?

Cat back exhaust systems are a great way to enhance the performance and look of your vehicle without having to take out a small loan. An average exhaust will start at around $300 and can go up to anywhere around $3000.

Why is it called a cat back?

They get their name because they replace the exhaust pipes from the axle, back. The catback replaces your exhaust from the catalytic converters back, including the mufflers.

How much HP does a downpipe add?

It's generally accepted that installing a downpipe will add just 10 to 20 horsepower, but that gain is noticeable when the engine is revved up.

What happens if you run a Catless downpipe without a tune?

No Check Engine Light (CEL)

This happens because aftermarket downpipe equips a less restrictive catalytic converter (CAT) – good for exhaust flow but bad for emission. Your car's ECU assumes that you are still using the stock CAT and thinks that the CAT is not functioning properly. Thus, the check engine light.

Does a downpipe increase boost?

From what I've gather by reading between the lines of everyone's feedback is that with a downpipe, sports or decatted, it's not about the overall numbers but the fact it allows a freer flowing exhaust, hence less strain on the turbo's load, with or without added boost..

Is installing a downpipe easy?

It's pretty easy. Have tools ready. Have wd40 or pb blaster ready. Soak all the bolts you're going for and let sit for 30 mins.

Does downpipe make your car louder?

Downpipes (catless) will make the exhaust sound more aggressive and deep.

What are the benefits of a downpipe?

Can you downpipe a naturally aspirated car?

In naturally-aspirated engines, the header connects directly to the downpipe. If you plan on upgrading one of these parts, the downpipe will give you a higher power gain. However, a good header will let your engine breathe better. Both are an excellent option if you plan on upgrading the turbocharger.

Are Catless downpipes legal?

Legality. If the negative environmental and health effects weren't enough, a catless downpipe can have steep legal ramifications. In some places in the US, removing or disabling a catalytic converter is subject to a $2,750 fine. Your vehicle may also be subject to impound which can rack up additional fees.

Is downpipe same as headers?

The downpipes have the catalytic converters. The downpipes connect to the exhaust manifolds(headers)and run to the cat-back, or, the section of pipe which has the resonators and mufflers and tips.

How much does a tune cost?

Money equates to time. Each setup is different, and also depending on what type of system is being used (piggy back, chip, stand-alone, supercharged, naturally aspirated, street or race only, etc) tune costs can range from $250 to $1500. Don't be afraid to spend money on a good tune.

Does front pipe add horsepower?

Maybe a few horsepower just due to better flow/pipe diameter increase, but negligible. You'll likely see better gains from the front pipe than from a cat-back, but a header will give better gains than both.

Will a downpipe void my warranty?

Well-Known Member. It should not void any part of your warranty, but a dealership may void it anyway. As Mark said above, it is probably not worth the fight once it has been denied, even if you are in the right.

How much HP will full exhaust add?

Everything that comes before the muffler, where the pressure is greatest and performance potential is highest, will remain tight and congested. MagnaFlow, an aftermarket exhaust manufacturer, says that its customers can expect horsepower gains of around 10 percent (which is a pretty commonly-quoted figure).

Does Catless downpipe give more power?

An aftermarket downpipe (MATOLA Performance Downpipe) usually larger in diameter and it either use a catted or catless configurations. Which able to create more power to your vehicle because it with high flow unit which allowed the turbo move gases away from the turbine more efficiently.

Keep in mind that putting on a straight pipe also involves adjusting your fuel injection and otherwise tuning up the car.

Does a cat back increase HP?

An Increased Horsepower

The cat-back exhaust system provides a vital boost to ensure the vehicle produces maximum horsepower and torque. The cat-back system has a larger diameter than a standard muffler; the wide opening creates more space for the free flow of air.

Is titanium exhaust better than stainless steel?

Titanium exhaust systems are approximately 40% lighter in weight than stainless due to the fact that titanium is much stronger and requires less thickness in the material for comparable strength. This weight savings when the ENTIRE exhaust is made up of titanium can add up to a good bit of weight.

What's louder axle back or Catback?

Traditionally, people that are looking for more sound than their stock parts produce turn to the axle-back option, which will increase overall volume and produce a more aggressive sound. For those looking to not only increase sound and volume but performance as well, the cat-back is the best option.
