y dont u need to upgrade the ehxhaust on a dohc??
if you put an str4 exhuast ur not gonna lose power, i dont think.....

 

Ok.Well I think iam just gonna run a strait pipe off the header then my Thermal R&D.

 

you don't need to upgrade the muffler on the dohc's i would for looks but you don't gain any hp.....for sohc's it should be one of the first mods......untill you doa turbo you can stay with the stock piping too but i recomend getting atleast 2.5 piping or3'so the air can breathe better

 

rice boy do you have emissions?

 

3 for n/a? are you crazy?

even turbo cars stay with 2.5 until they are making serious power

 

I have no idea if we have emissions.

 

lol thats why i said when you turbo iti should have wrote it a little better but thats what i meant...im not stupid even i hate people who get 3' for there n/a
