Ported JDM 4-1 ?'s
I just ported the JDM 4-1 today and went to a muffler shop and asked how much to weld it form the outside I was told $80 USD!!!
1.How much have ppl that have done this payed to have it weld?
2.What is the best way to clean the headers from all the grease? I am thinking Simple green
3.Do I need to worry about anything such as corrosion and such for the porting?
TIA
