I do not know how to make my exhaust pop.

How would I go about making popping noises out of the exhaust? What is required?

Do I have to buy a new ECU and modify the exhaust?

I'm bored of having a boring car and I have no money because of school so I want to make the CR-V something more.

The pops you hear on many cars are from turbocharger wastegates. It's also costing power and damage to the engine. You say you have no money and are in school. Do yourself a big favor and run a stock engine and car and save your money instead of wasting it on crap to make your car sound different. A boring car that is dependable is far better than a car that breaks down weekly and you have to keep spending a lot of money on to keep it running and need to buy top line gas for.
Now if you're not going to listen, plan on spending a bunch of money to get what you want. You would need a different ECU, wiring, a turbocharger set up, new exhaust and more. Figure about $2,000.00 as a start with the top end being however far you want to go.

Thank you Steve W. After hearing all of the negative effects that this will do to my car, I'm ignoring all of your advice and am dropping the exhaust entirely. HAHA, just kidding. I need to get from A to B reliably. Thank you for taking the time to answer :)

Reliability has a lot going for it. Especially when you are in school or dating. Plus that "boring" car is a lot less likely to get the attention of the police.

Hello, another question I've run in to.

In my 2011 Honda CR-V, the TPMS light has been on. I've taken it to Canadian Tire to see which sensors needed replacing and turns out 3/4 of them are dead. At $70.00 a piece, its quite expensive.

I am writing here to ask if there is a way to disable the TPMS all together to get rid of the light. I don't need a TPMS to tell me my tire is flat, I check them regularly.

I am willing to do some complicated DIY if it's required or if it's as simple as removing a fuse.

Any insight into this would be great, thank you!

Welcome back. The short answer to this is there isn't a way on modern vehicles where the TPMS is integrated into the system.
The longer answer is that because TPMS was made into a "critical safety" system the manufacturers in most cases integrated it into the vehicle in multiple ways to cover themselves from lawsuits. For instance in your CRV let's look at the fuse option - Simple Fuse 20 powers the TPMS module. However it also powers two other circuits, one for the rear fog lamps when sold overseas and the AC clutch as well. So pulling the fuse will cause the loss of air conditioning and TPMS as well as the Euro fog lamps. Next you have the option of disabling the system by simply unplugging the module. However this also has a larger drawback, The module is coded into the safety systems and is watched for it's presence by the communications network. As such, unplugging it will trigger a few things, one the check engine light will come on indication a communication error, two the TPMS is linked to both the stability system and the traction control systems also added as "critical safety" to vehicles. That means the TPMS lack of communication will turn on the ESC and ABS lights if it is missing. The only way I know of to fully eliminate it would be to rewrite the coding in the body control module, ABS module and the powertrain control module in a way that the vehicle thinks it never had the TPMS module installed as other countries do not require it.

You basically have two options, ignore the light or replace the sensors. There are less expensive sensors than the 70 dollar ones. The universal ones are about 1/2 that price, but all of them have to be programmed to the car.
Sorry for not being able to say - pull this part and you're good to go. With the integration levels on modern vehicles it's hard to do much of anything without requiring programming or even systems that cannot be removed. At least your CRV isn't like some cars where you have to initialize just about every replacement part just to get them to run. BMW is like that in modern ones, even replacing a battery or spark plugs requires a scan tool to tell the computer what you did.
