Hi guys. As the title says, is it safe to go to the local exhaust shop and have the crack in my manifold welded? Probably a stupid question, but I thought I would ask before I messed it up anymore. I just wanna be able to drive the car until I can afford to replace it with a better manifold. Thanks.

what kind of material? either way yes its safe. but if urs is a aluminum mani...go to an aluminum specialist. and if its cast iron, go to a cast iron specialist. cant go to any muffler shops cuz like for example if urs is a cast iron, u have to bake the mani in the oven before u can weld on it or else u will have new crack along side the new weld...

where exactly is the crack? in most cases it is ok, and you should be alright with it for a while...but if it cracks once, most likely it'll do it again

Seen many aluminum exhaust manifolds?

a long time ago when type-r manifolds were the "manifold to run" like back in 97 98 we would cut the flange off a gsr and weld it to the type-r manifold runners to make the type-r manifold fit a gsr head... it worked fine untill it started to crack, fell off at the street races ..lol thought about it and just drilled out the type-r flange to fit the bolt pattern. well im way off the topic but personally i wouldnt weld a crack especially on the hp you are able to make now in days... a maniflold carries a great amount of volumetric pressure.....but then again, if u just need it to drive arround untill u get a new mani.. then its all good...peace
