well i think its pretty loud. If you want to try it or hear it in person stop out my way and i’ll let you hear it 
i ts same design as borla XR1 just 50-70 bucks cheaper
Hell i’ll let you borrow the muffler to put on your car to see how u like it. Or if you want to buy it i’ll let it go for a good price… they are 105 new from summit. i’ll get you a good price on it. i didnt weld it to my car and it has one side thats 4inch inside diameter so it will slip on a 4inch OD exhaust tubing. I also got a section of straight 4inch piping 48 inchs worth that i didnt need you can use if you want.
but its definately a straight thru high high flowing muffler
