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 |

A neighbor of mine looked at my new SSI's and said....
They're gonna rust... He is an aerospace metalurgist for GE aircraft engines and told me the SS tubing grade is non-magnetic and will rust. Not as much as steel , but it will... As per the one in pieces, explosions down the exhaust will do that..... My POS honduh used to periodically do that and either blew out one of the bends in the pipes or sent the guts of the muffler shooting about 60 feet out the rear of the car..... That's 3 factory exhausts in 70 k miles and loads of excitement for people following me..... That crack all around looks like a combo of rust and fatigue.... Ken |

Something about the tubing taking longer to cool and water (moister) collecting in there that will cause them to rust. While they are better than stock exchangers they do need to be checked. I would think a easy pressure test should tell you if you have a leak in them or not. Plug one end with some sort of rubber plug, the other end the same with and air in let and listen for leaking air? (IMG:style_emoticons/default/confused24.gif) |
