JPersons. What heads are you running? I have AFR 165's. I know that if I had the 185's I would have about 40 hp additional - or roughly 366 rwhp. And yes I do have IRS, and side pipes with glass pack material. I am very happy with where I ended up this week - it has been a blast. And manana is time for another run!! Have a great weekend!!!
