ok let me post some videos for u in a lil bit, keep in mind the downpipe is only about 2.5 ft long so the noise u do hear would be very hard to hear if it had a full ex.
see if it kinda acts like what ur engine is doing.
have u checked the same for wiped lobes, possible rocker stud pulling out.bent push rod etc
will it rev in nutral or park?
whats the fuel system have for line size /pump what size injector
