will this universal system work?

I had to work. I did get to take a spin and it sounds great. Not to loud not to soft, the Harley next to me at the light was way louder. 4 year old daughter said Cinderella should have gotten a Barracuda from the fairy instead of the carriage! It's even lower then I thought but my car is really low in the front. A couple of baby speed bumps at Walmart scraped as did a dip in the road at 35mph. I'm off tomorrow and it should be nice for pictures. I ordered some stainless slash cut tips from Jegs but they are 4 days off still. So I haven't cut off the excess yet and that looks bad. Also need to adjust a bit as something is knocking in the back when idling in gear.
