Great Kit

I got the full delete with the downpipe and 5" exhaust. The videos for the install made the job a lot easier and was able to do all work myself. I would definitely recommend this to everyone and love the tone and power that I got from it

So far so great! Ridiculously better than new. Still working on which level for the economy but all in all as expected we're both breathing easier. Vids were a bit miss leading( shortened apps) as was the hoses supplied but again great results. Needed more credits to complete. Somethings else to bring to your attention. But happy toy. Thanx
