When the was trying to

When the was trying to place the gasket on my stock down pipe, I noticed that the pre-existing holes did not lined up with the carriage bolts. I had to slightly cut the gasket’s pre-existing holes in-wards in order to fit flush.
Luckily the resonator’s pre-existing holes barely cleared the carriage bolts from my down-pipe. Found no leaks after installation.
I would like to respectfully request a replacement gasket for future use at no cost .
Furthermore , the product’s sound it’s unique and I love it !
