Washed the engine bay, now it's louder
 

I washed the engine bay and under carrige this weekend and now car sounds louder and deeper. I still have stock exhaust, probably old and rusted. Can this be a serious problem?

if u preasure washed it u could have blasted off some of the rust and now u could have a hole, which would make it louder.

What did you do to "wash" the engine bay?

I used Engine Brite.

I think Coldsho was right... you probably busted a hole in your exhaust somewhere with the pressure spray... can't think of any other reason... I see that you're in Chicago, so the snow and salt possibly did your exhaust in. I used to have a 97 VW when I lived in Michigan and the exhaust rusted out at 75k miles....

here's the reason to get a new exhaust. Cattman headers and custom cat-back.

Damn right... do it do it... :nod:

That's exactly what I did with that VW... I replaced the stock exhaust with a Neuspeed and it was so worth it...
