If this is a DIY project, i recommend shifteck. Sawzall for the pipe, Dremel for the heat shield, and simple hand tools for the clamp nuts/bolts. You can easily swap it back to factory if you don’t like it or decide to sell the car.
A mufflershop can do this for you for about 60-80$. No need to pay for an overpriced kit thats essentially the same thing the guys at the shop will use
I agree about Shiftek, excellent quality, easy install and easy to swap back if you want.
I don't have a Sawzall, but I did use an exhaust pipe cutting tool I bought off of Amazon.
The tool makes a super clean cut with no mess.
I did use a grinder to get the clamps off the heat shield though.
Great mod, really opened up the sound especially during shifts.
