Let’s dive right in. Apply an Epoxy Bond. If the hole is small enough, you can use epoxy to seal the leak. Wrap it with Exhaust Tape. An exhaust tape is an ideal solution if you are dealing with a larger hole. Use an Exhaust Clamp. Cover the Hole with an Aluminum Patch.
Is it hard to weld exhaust?
Another problem is that it is not hard to weld before you attach it, but if you have to repair a broken exhaust, it’s much more difficult. Welding heats two metals to the melting point and introduces a filler material to fuse the materials and create a strong bond. There are several types of welding you can use.
Do headers make the car louder?

As for drawbacks? Shorty headers aren’t as loud as long tube headers, although they’ll definitely have better sound than your stock manifold. You can choose unequal length headers for better sound, but equal length is the way to go for consistent gains in performance.
Are downpipes and headers the same thing?
Re: Difference between Downpipes and Headers (DaPeaz) Yes, but they are only marginally better than the dual outlet manifold and down pipe configuration. That is correct. Headers eliminate the exhaust manifold and the down pipe. Some headers also eliminate the catalytic converter.
Are headers hard to install?

How much horsepower does straight pipe add?
As stated in the intro, a correctly designed and tuned exhaust system can increase torque and horsepower across a wide range of the power band. While this gain usually isn’t “big” – we’re talking about a 2-3% increase – the modification offers a few benefits: An exhaust upgrade is relatively cheap.
How much horsepower do cold air intakes add?
That’s why a cold air intake is a small investment with a rather big payoff. It makes such a big difference, in fact, that the simple process of redirecting the filter to draw cooler air is good for a horsepower gain of about 5 to 20 ponies in most cars.
