I gotta big ole hole in my front pipe that leads to the muffler. Hi all, I am new here and I just bought a honda accord 91 lx about a month ago. I turned my car this morning and noticed white smoke coming from the underside of my car close to the front and then it went away, upon driving the car i noticed it sounded like a drag racer. I took it to colemuffler and they estimated the cost to replace the font and middle pipes for 400 dollars i aint got that kinda cash so I was wondering how long a window do I have that I can drive the car for before it totaly goes south???? I intend to replace the pipes myself soon and I found all the parts and it comes to a grand total of 118 dollars. thanxs!
