Exhaust 101 question
 

I hadn't noticed this before the other morning. I backed "The Beast" out of the garage to let it idle/warm up a bit before changing the oil. The air temp was around 40 degrees so in the rearview mirror I could see some exhaust 'smoke' coming out of the pipes. I got out and walked around to the back of the car to look at it. I was surprised to see only two of the four openings were 'puffing'. I expected to see 'smoke' wafting from all four of the tips.

Is that correct for a bone stock exhaust system?

If so, would it be harmful to somehow open up the other two? Seems silly to have four openings and only two functional.

yes only two outlets work, I would buy an AM system, liven up the car alittle.

Yup, that's how they are stock. And yup, it looks kinda goofy on cold days. I wouldn't open it up though, replace the muffler if you want something with both sides functional.

Thanks for the replies. Guess I'll have to live with it for awhile as there aren't any $$$ in the budget right now for replacing functioning mufflers.

only thing you gain is resonance

If that bothers you and you decide to put on an aftermarket exhaust, don't get the Corsa as they are the same way.
