Hey guys i just wanted to ask has anyone changed their exhaust manifold for the Buschur one? My evo is at the shop and i was informed that one of the bolts holding my stocker was cracked. Have any of you experienced this before? It's making me a little paranoid, but the rep of the shop is good. They have evo experience. Just a little worried if there is anymore damage anywhere else on the car.

 

Do you want information about the Buschur ported/coated stock exhaust manifolds, or do you want help with your worries? To answer your question, yes, tons of people have gone that route, because a ported stocker is better than an aftermarket tubular, and it costs less. I have one myself, and it came with new hardware (bolts/studs/gasket), which may be something that interests you.

 

do you need another tune with a ported manifold?

 

no.. not nessisarily

 

I already have the manifold. Just looking for answers to my worries.

 

pure player,where did you purchased your megan DP?I cant find one for my IX with ACD

 

you can pick up some stainless steel studs/bolts for the manifold that would resist rust.

 

that's because they aren't out yet. it should be another month or so.

 

no u dont need a retune...

 

Bolts for what part? manifold to head (studs) or manifold to turbo?

 

I went from 2 cracked megan manifolds to the stock ported one

 

i didnt change mine , just got the stock ported by buschur which is the same thing that that they sell except for the jet coating.
and its well worth it

 

Nevermind, for some odd reason the manifold they sent me had a broken bolt stuck i it. All is well now though, thanks guys.

 

Do you know exactly what kind of performance changes one can expect by porting the manifold? I really want to get mine done, but I can't seem to find any numbers anywhere.

 

There are no exact numbers. You usually do it in conjunction with a ported/coated 10.5 hotside and ebay o2 housing. Doing one without the others isn't very effective.
