| Post subject: | Exhaust Heat |
Looking at getting new exhaust. In the process i'm wondering what i can do to minimize the heat that comes through the floor form what I can only assume is the exhaust. What options are there and what works. I was thinking about that heat wrap stuff from the engine down to the cat but is there a heat sheild or anything that you can put between the exhaust and the floor that works? Thanks |

Some factory systems (like the subie front exhaust section I have) have a pressed half round heat shield ex aluminium to protect the floor & sensitive components. |

That was kind of what i was think about. Is there room between the exhaust pipe and the car? I imagine to be effective they would have to be floating. I.e. a layer of air between the shield and the muffler and a layer of air between the shield and the car. I was thinking about using that heat tape as an alternative but all it would take is the taped exhaust to catch on 1 speed hump and it would be very messy. |

I remember reading somewhere about heatproof insulating coatings for exhaust's , sort of a paint on type thermal blanket thet wouldn't tear on things like tape would . No idea where from though , maybe talk to an oven manufacturer or specialist engineering works that deals with heating fabrication . |

Ceramic coating works well but still $$$ And yes, those shields are fully floating but the gaps are in mm not cm |

There was another one being touted as a spray on type thing , spray on thick and several coats so you ended up with a 3 or so mm thick blanket like coating . Not sure just how much heat it blocked but they were saying reassonable . |

Sorry to hijack the thread but what kind of radiator has been used for the front mount? |

Yes, his was custom made, but it only doesn't heat up 'coz he's got NO THERMOSTAT in that thing. I use an Alfa-Sud item on my LS. So long as you carefully fill it, and make sure it is full of water, ie. no air, it works a treat. edit: oh, and long-tube headers make the floor hotter than usual, too. like mine. The 3>1 collector is just under your feet, it sure gets warm.

I can actually feel warm air coming up the gearstick collar. Makes me wonder if i might have a small leak where it connects to the catalytic converter.

Rover minis have a full length heat shield under the floor above the exhaust. Get one from Steve at Brickworx and you'll be sorted. If he hasn't got a good one you can buy the quilted alloy/fibreglass/alloy sandwich sheet and make one youreself. Don't wrap the exhaust in the fibreglass wrap if you plan to drive the car really hard. You will just deform/root your exhaust. I had my extractors wrapped in the fibreglass bandage. The insulation was so good you could touch the exhaust straight after a drive but the welds all failed and the pipe warped like it was made of play-doh. |
