So then... what exactly is a test pipe? If you want to feel really helpful, what are the components of the exhaust in order?

Thanks squad...

Also... what the heck is the stock redline on the IX MR? lol omg I feel like such a noob right now...

TIA

 

A test pipe is just a straight pipe that replaces your Catalytic converter. It don't filter, and you will fail emissions with it.

 

A test pipe is just a piece of tubing with the correct flanges welded on to be a direct replacement for catalytic converter. It won't pass any state or federal inspections, including emissions. It can also cause your car to run bad on certain cars.

Components of the exhaust system are going to be:

Exhaust manifold
Turbocharger
Downpipe
catalytic converter (aka cat) OR test pipe
cat-back exhaust (includes any resonators or mufflers)

I might be missing something... I feel like I am for some reason lol

 

No... that makes perfect sense. I mean, I'm not a moron... I do most of my own work, I guess I had just never heard the term test pipe used for a pipe in place of a cat.

I assume the logic here is so you can just bolt a cat into place for inspection and then put the test pipe in for uhhh... non-inspections lol?

Anyone have the redline for me? (right after I mention I'm not a moron lol)

 

wikipedia is your new best friend

 

You're right about feeling like something is missing...the o2 housing

 

what is emissions

 

Whats the purpose of tires on a car?

 

Its what happens when you first engage a girl in the park...at night

 

Eh... I have no good comeback...but whats a forum without some stupid noobs?

 

Lol

 

what happens if a cop pulls you over for going 40 in a 25??

you tell them only reason why you was speeding because you have to poop :P

 

Ducks Fly Together

 

What is the purpose of a test pipe? More hp? How much louder does it make your exhaust?

 

If you are serious on that question,

It should get it a bit louder, depending on many exhaust factors like pipe diameter, etc
Having no Cat is less restrictive, therefore, your engine will have an easier time "pushing" gases out to start a new cycle
