hey all, i would like to know if anyone has any pointers on the parts im puting in the evo on thursday. i used the search feature and found all i could that was relevant to my question so this is the question i am left with for all of you. im replacing the stock system from the headers back with the polished ss manifold, helix 02 housing & down pipe, perrin straight pipe and the hks hi-power cat-back. i would like to know from your experience with these parts is there anything else i should replace along with doing the full exhuast. all comments and constructive criticism are welcome. thanks for your time.


edit: im aware that i should replace the air filter to a high-flow filter.

 

new gaskets

 

i forgot to list i ordered them as well! thanks for the reply

 

how about the exhaust hangers?kartboy sells a set of them.also when i did this i put a layer of heatshield tape on the oil pan since running catless makes the pipings more hotter.just an extra thing that i did to prevent from the oil getting too hot right away.

 

wrap your dp with some DEI header wrap and silicone it while you're at it... contains the heat in the pipe and not so much your oil pan plus it helps rush the exhaust out faster, or, so they say... I just used it for the heat containment part mainly...
