It's those general N1 reps isn't it? With the 4.5" tip.
Thb I have had those and if I bought them again, it would need 3" piping and a custom muffler.
They don't so id just go to a muffler shop. It's way cheaper.
Just keep in mind, they sound decent for the price. They are 5x louder than stock.
If you don't drive a manual your going to have a hard time keeping the noise level down.
They have a small rasp to them. The only way to get rid of it is to use the silencer, which doesn't do much but smooth out the turbulence in the exhaust because stock engines don't move enough air.
