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 |

FWIW the factory used a form of stainless tubing with mild steel heater boxes, so the boxes would rust before the tubing.

FWIW the factory used a form of stainless tubing with mild steel heater boxes, so the boxes would rust before the tubing. The oem tubing was also much heavier wall thickness and could easily withstand the pressure of backfires. T304 stainless is very corrosion resistant at temps up to about 800F. When it is kept above 900 deg. for an extended time period changes take place within the grain structure that dramatically reduce the anti-corrosion properties. The technical term is carbide precipitation. |

[/quote] Yea, the SSI's are about half the thickness at the flange that mounts to the exhaust port, which is why so many have trouble sealing. I'm also fairly certain that the SSI's use welded tubing, and my guess is that it would be better if it was DOM. |
