Quality Nicely packaged,everything comes in bubble wrap,comes with *instruction* and stickers.

Comes with.Test Pipesx2,Bolts Nuts and Gaskets(metal,the good stuff)

Install(MD Fabrication Richmond BC) about 2 hours,if you do it by your self be prepared
to be under the car and in the engine bay from the front
Here is the pictures and videos before and after.If you have a request for a sound clip write it down and i will make one

Review,so lets talk about normal driving with shifting under 2.5-3k,the sounds is pretty nice with a mean tone to it which is pretty reasonable for non resonated ones.Over 3 to 5 is very raspy and when i say raspy is similiar to ferrari f430 sound,ofcourse its not a ferrari but sounds similiar sound,from driving for about 6 hours people give you compliment and ask what kind of exhaust do you have.
Overall iompression,if you like raspy mean sound this is the way to go.

Sorry about the comments for the videos wake up at 4.30am))
