Sounds alright make sure you have afm disabled, makes it deeper and more enjoyable but not as loud as you think it will make it. If you want loud you’ll have to do the resonator further back as well, as well as an issue of the pipe not being long enough to cut the flapper out so that’s another restriction. I welded mine open. Fit well after the muffler but the inlet pipe is a little smaller causing you to have to really tighten the exhaust clamp down to get it tight. Does not completely seal so there will be a slight leak around the edges unless you fix that with some welds or exhaust wrap/tape. But for 80 bucks it’s a good deal and the easiest way to diy it the right way.

This will take you about 20min to install. Super simple. YouTube has a great video step by step. Instructions that come with it you can't even read so don't try. Muffler shop will charge you about $150-$200 so this is much better option and if you trucks lifted it's even better.

Actually works!

Wasn’t a direct fit, but worked well with some tweaking. Also had to trim about 8” out of the middle section (comes with three sections) to meet length. One of the bends was slightly off for factory exhaust tips to align in bumper, but for the money it was fine.

Used on a 2005 forester XT with stock headers, fit fairly well. needed a bit of coercion but sealed up nicely so far. certainly better than other super budget options I’ve tried and had bad luck with.
