People say they bought big tube but when you compare against regular tube its the same they cost the same and they are cheap replicas from ebay. A bigtube replica cost like 250 - 350 so everyone is giong for the cheapest one the regulartube for 170 - 200

I'd have to do some research as this wasn't my header and I haven't heard about dyno # yet! It was bolted to a sr22ve
