Is there a bung I can get to put in the exhaust, its a turbo model, will I just need to put a bung in 1 of the back boxes or both of them. They're aftermarket back boxes about 3 or 4" dia i'd guess, where do I start to look for a bung for these?
Edit: Ok, I found a baffle bolt in type bung. Will I need to fit 1 in each tailpipe? Also, if i stick some steel wool in behind the bung will this help reduce the emissions in any way and how will I get the steel wool back out afterwards, will it come out with the bung removed under the pressure of the exhaust itself?
