Something's not right. Smells like exhuast in the cabin, and a very slight backfire has developed on the left side...like a very subtle 'pop pop pop' at idle, and a more pronounced, single 'POP' on decel around 2800-3100 RPM. I've got it paired up to a Triad exhaust. What gives?
I swore to my wife that I wouldn't have the car up on ramps for a while since I just pulled it down (after 2.5 months) 2 days ago, so I took it to a custom exhaust place here in town and had them do the install. They said I needed new hoses (parts 21 & 23 here, hope you don't mind George!). The original ones were put back on, but they're pretty deteriorated and have small holes/cuts in them. Could that be it? I wish I understood how heat exchangers worked. I did a search on google hoping to learn just that but came up empty. Yes, I realize that if there's exhaust pouring into the cabin it could potentially be fatal. I drove the car home with the windows down. (IMG:style_emoticons/default/smile.gif) I intend to contact the shop today, but was hoping to get some feedback from you all first. Thanks in advance Reid |

Sounds like an exhaust leak where the h/e's meet the head. Drop the exchangers and get a BIG ass flat file. Take a sharpie and color the end of the flanges. Then take the file and run it across BOTH flanges at the same time until the sharpie is gone. Then file off the same amount of the top of the mounting tabs. Make sure the sealing area on the head is clean and not buggered up. Get new copper gaskest and re-install.
You may also have some residual oil in the tin that is burning off. The pop-pop-pop at idle sounds like an exhaust leak though. |

I agree with the following... MUST be done! A run of the mill exhaust shop will not do this and hopefully they installed the gaskets at the HE/Muffler flanges.
Final torque-down is after they're warm to ensure no leaks. Sounds like an exhaust leak where the h/e's meet the head. Drop the exchangers and get a BIG ass flat file.
