2000 Oldsmobile Silhouette Q&A

2000 Oldsmobile Silhouette Question: 130K on it. exhaust? manifold?

i have a 2000 olds silhouette with 130K on it. While stopped at a red light, the exhaust suddenly became very loud. i believe that it was coming from the front of the vehicle rather than the muffler in the rear. Before this, it would occassionally miss and/or small backfire if in a lower gear other than D. Any ideas on costs? -
Answer 1
sounds like poss head pipe came loose,ck with a muffler shop for est. this needs to be looked at for proper est due to poss broken bolts.if it just came loose maybe 60.00 if bolts are broken who knows -
Answer 2
Something in the exhaust system cracked or broke...need to find out EXACTLY what needs to be done to give an idea of costs... -
