    Exclamation Header and solid mount prob.

    I just installed my ssautochrome lt's and spohn solid mounts. but the drivers side header is hitting the floor pan of car and y-pipe will not clear to fit on. when i took the stock mounts out the pass. side mounts were the same heigh but the driver mount was about 1/2 in. or less higher than stock, called spohn and said they've never had this problem before(with header hitting floor pan) and no way the mount could of been deffected. i did the hole installation to the pin point and was going very smooth till this happened... Has anyone ever even heard of this happening any help will be appricated

    Its not your motor mounts, its the headers. The drivers side collector is angled upwards for some reason, they are all like that. I know, I have a set as well. Mine didn't hit the floorboard, but they came close, and made it a PIA to get the exhaust fabbed up.

    Only thing you can reall do it take the header to an exhaust shop and see if they can bend the collector down so its not on as much of an angle.

    ANother reason not to buy a LT without a good rep in the Fobdy world.

    Sorry to hear that man, looks like you need a reputable place to bent it down slightly.

    Cut of the collector and re-weld it on at a corrected angle.

    thanks so much for the info!!! i was bout to buy some poly mounts to c what it would do. think im gonna try to cut the collector right before the pipes come into the collector then try getting a muffler shop to bend a pipe that might drop it down to the right angle then ban clamp it on. think that might work? thanks for all your inputs


    but the ssautochrome headers had no clearence issues getting them in other than the drivers side floor pan, didnt have to drop the steering stem and could slip them in with the car bearly lifted off the ground and did it all myself at 19 years old so i would recommend them for stainless steel lt's for the price!!
