So I am cruising down the street at 45 mph and when I let off gas and start to stop I am noticing a ton of exhaust coming in my van even with the windows down. More so than ever before. I would have noticed because it is giving me some serious headaches now. Literally. I thought maybe my headers were coming loose again or cracked but after checking this morning they are totally fine. I did notice that there is most of the rubber lining missing that is on the van frame where the doghouse sits. I wonder if the headers melted it off??? The foam lining that goes around the edge on the doghouse is mostly gone too. Where can I buy both of these and what are both of the linings called? Keep in mind they are both different on my 72 g20. I would love to be able to order it online or go somewhere here in Huntington to purchase asap. Can't keep driving everyday with this exhaust. Could it be something else too? Thanks guys.
