Hey guys, well for about a year and a half now i was running slp longtubes, slp off road x pipe, and slp loudmouth catback. My inspection is due the end of this month and i couldn't find anybody to pass me without cats. So, I purchased the slp high flow cats that are made for my off road midpipe. I put them on and they really quieted the car down, but gave it an awesome tone. I really like how it sounds now. My question is, will this throw off my dyno tune at all considering I had it tuned without cats?? I will be getting dyno tuned again because I will be putting my front mount on soon. But I just wanted to make sure it really isn't hurting my car to drive it around with cats on now when i had it tuned with no cats because of my blower. Also, how much hp do you think i lost?

South jersey here and we have emissions so it sucks. I drove the car a little to see how it responded and got up to about 9psi and it seemed to be fine...
