Thanks again everyone......Jake does this guy at Allbright is he a chromer or polisher?I might give him a call.
Sean,you could be right as inlet temps are not that hot but my friend has a downpipe in HPC and the exh temps were the same when under the same conditions.These did reduce though when thermo tape was applied.Im just starting to get a bit sceptical about this product....Still not decided if it does or does not work.
