I don't know how close is too close to have things next to the pipes on my kit but I don't want to have any problems. I didn't wrap the pipes before the kit went in but I did wrap the downpipe after it was installed(not easy). Now my concern is that on3 has a charge pipe with a silicone coupler running pretty close the the up pipe and I don't want it to melt the coupler. By pretty close I mean like 3/4 to 1". What do you guys think? The more I think about it I think I should just go through the extra trouble to take the up pipe back out and wrap it.
