Straight Pipe - Mazda 6 Forums : Mazda 6 Forum / Mazda Atenza Forum

Hey
So I keep hearing the term straight pipes when it comes to exhausts, and I am wondering what exactly that is and how its done, and what I would need
I did a search but couldnt find anything specific besides vids of how it sounds.
Anyone know off a DIY or a How-to on here?

I believe you basically remove the mufflers.

Straight pipes typically refer to running your exhaust without catalytic converters. Coming "straight" from the exhaust ports. This allows for more air flow and a deeper growl of your exhaust.

The downside to having them are passing emissions tests in stricter states and keeping the check engine lights off your dash.

Well I don't live in the states so I don't have emission tests
And how high is the chance the check engine light will come on if I actually do that?
Also what diameter pipe would be needed?
And could I just use any EMT piping?

Check engine light isnt going to come on by removing mufflers. If you remove precats they will.

If you arent able to weld i suggest having an exhaust shop do it for you.

If you plan on doing it yourself you need a measurement of outside diameter of the current pipe. Any place like NAPA or carquest or crappy tire will have sections of pipe. I believe out stock pipe is stainless so you wanna try put the same stuff in place. Not familiar with EMT pipe. Please explain.

I have my cat and resonator on. I took the resonator off, but it didn't pass smog so I put back on

So technically I could just go to minute muffler and ask em to take out the muffler parts of my exhaust and put straight piping in? Also what exactly are the mufflers for? Just to muffle the sound?
And while I am at it I could get better looking and slightly bigger tips also right?

They might not do it & they might be happy too. All depends on regulations & how "proper" the shop is. They arent supposed to remove emission related items from the car. Id call and ask them first.

Mufflers muffle sound. Thats all they do. Bigger nicer tips for sure.

I would remove the stock axle back as a complete.

Have them fab up a new axle back complete with flanges so you can revert to stock easily if need be.
