exhaust question, quite cores

[jareddustin]

i have an aftermarket slip on exhaust on my turbo s from agency power, dual tip. i like the exhaust but on a long ride its a little much, looking to quite it down some, i found a plug that aftermarket assassins makes for their dual tip exhaust, its made to only use in one of the dual tips. in the details it says its only for their exhaust but if the dimensions of the tube are the same would it work on my exhaust? dont want to do any damage to the exhaust or the motor by using a wrong part. i looks like it attaches to the hole for the spark arrestor which my exhaust has.
