When upgrading car exhaust, do you have to upgrade other parts as well to connect exhaust?

[Anonymous]

I just ordered Corsa exhaust for my 2013 mustang, but im not sure if I need to upgrade other parts or it will be fine

I had used a different mustang same year with corsa exhaust and love how it sounds but it was a test drive. My mustang is stock so its low sound. So for exhaust upgrade do I have to change other parts?

[MrOracle]

Typically today, what you are buying is a "cat-back exhaust" meaning that it replaces everything behind the catalytic converter (pipes, muffler[s], and tips). Usually the old exhaust is cut off (or unbolted on some cars) and the new exhaust welded or bolted on in place. Typically, but not a8, the hangers are in the stock position so that it's easy to do that swap.

More serious performance builds include replacing the stock exhaust manifold with headers and even replacing the cat with a higher performance model, but that's not only a lot more difficult and expensive but also has legal ramifications (messing with the cat is a big no-no in many states).

good to know. Since the exhaust systems are stainless steel and don;t have to be replaced every 2 years I have not touched an exhaust system in 30 years.

[MrOracle]

Most factory exhausts are NOT stainless steel - that's largely only true of high-end performance cars and aftermarket exhausts.

[Asker]

Oh I didn't know that

[MrOracle]

And not even all aftermarket exhaust, though many are stainless. And if it's stainless, they'll definitely advertise it as such, so if you don't see them say "100% stainless steel" or something similar, then you can assume they're using regular steel.

Here in California, where most areas don't have snow or salted roads, it really doesn't matter, but if you live in a snow state (or a snow area), then having stainless steel (which is much more corrosion-resistant) can be an important feature that's worth paying more for.

@MrOracle well. whatever they make them out of today, they don't rust out after two years like they used to.

[Asker]

@exitseven I ended up purchasing Corsa Sports exhaust. The good thing I live in Cali so I dont have to worry about snow. I used to have a car from the east coast and it was super rusted from the snow over there

[MrOracle]

@exitseven They have better anti-corrosion coatings available today, so standard steel will last longer. Still not like stainless will - though stainless certainly CAN corrode if abused enough - but it does better than the bare metal exhausts that were used in the 70s and 80s, that's for sure.

@MrOracle I have owned 5 or 6 vehicles over the last 30 years and usually keep them for 12-15 years. I have not had to replace an exhaust system in all that time. In he 70s people replacedexhaust systems every 2 years.

[Asker]

@exitseven how do you know when to replace them?

[MrOracle]

You replace your exhaust when it's rusted out. Back in the 70s, they were using recycled steel to make cars - and didn't have the technology to properly refine it and remove the impurities - plus they were still using old-time galvanizing to protect the steel. As a result, the exhausts and the entire cars were rusting out very quickly, even in places that didn't salt the roads, but especially in places that did. The thin metal of an exhaust could rust out in only a few years.

Protective coatings are much better today, as is our steel refining, so we don't have such serious problems. But salt will always be a big problem for steel, unless it's stainless, which slows down the corrosion that much more.

[Asker]

Oh okay got it. Which exhaust did you have?

[MrOracle]

I had a Yonaka stainless exhaust on my old Honda Civic, but I've just got the stock exhaust on my current car (an Acura TSX) as I'm past my racing days. Especially at today's gas prices, I try to keep the RPMs below 3000 at all times these days. LOL.

[Asker]

Lol same here gas prices are so high I sometimes rather walk 😂 and try not to drive so fast to save on gas

Usually there are hangers and clamps that need to be replaced. The gaskets that go between the manifold and the tailpipe need to be replaces too.

Thanks for the MHO😎

should be fine leaving it the way it is but it might depend on the car.

[gabby100]

Why are you wanting to up grade.

[Asker]

Sound is too quiet since it is stock exhaust

[gabby100]

Yes but there are a lot of things that need to be taken in to consideration when you start altering things. Firstly performance. I always remembered what dad said about this. Noise is power, the exhaust is tuned to that car..

[In_Trance]

Did you order a full system or Cat-Back

[Asker]

I just ordered the Corsa Xtreme Axle-Back Exhaust with Polished Tips... so im not sure

[In_Trance]

New hardware and gasket if there is one. That's all.

[Asker]

Oh okay thanks!
