Ok, here goes. What is the difference between axle-back and cat-back exhaust?

 

just what it says ... the axle back starts just before the axle and the cat back starts at the cat.

 

Hope this gives you a little visual of it. It helped me learn.

 

Godd info.

 

very good example!

 

Thanks guys...I learn better visual and im pretty sure others do to.

 

nice work, very artistic

 

So cat-back would replace everything up to the manifold?

 

No... Just up to the cat.

It goes, engine - exhaust manifold - cat - exhuast pipe - resonator - more pipe - muffler - tip

-THE DON

 

What's a good brand of cat-back to get. I'd like to have a deeper tone, not so buzzy.

 

get one custom done. or check out magnaflow's website for a clip of their catback

 

cat back=u replace more of the exhaust system
axle back= basically the exhaust and little bit of the pipe prior and of course the tip

 

no cat back exhausts...the cat, mid pipe and resonator are all welded together...

so its really axle back or manifold back...

you can go to a muffler shop and they will cut after the cat and weld in new stuff, but its no shade tree mechanic stuff...

 

I've got a little red x. Is that the good example or am I too late to see the picture(s)?

 

some good info.

 

Does the xB have a flex pipe just south of the exhaust manifold stock?

My cavalier does and I just had to replace it when it broke. The flex pipe, down tube, cat and o2 sensor bung, along with both flanges are on one tube... about $350. I just put on a Pace Setter header that replaced the flex pipe with a more standard downtube.

 

no flex pipe...
