Doughnut flange to ragular flage fitment

got a question! I just realized that my magnaflow catback is doughnut flange and my invidia downpipe is regular flat flange. How big of a deal it would be putting them together? Will I most likely have a leak? Should I bring it to a shop to have a regular flat flange welded onto magnaflow catback?

 

I had the same problem, I just put a bunch of RTV silicone in it and it worked fine so far.

 

cool, thanks for a quick reply. I appreciate it.

 

I think you should have a new flange welded on, so no problems in the future.

 

yeah, I will try a crashgasket first and then see how bad it is.

 

CRUSH.. sorry if my accent confused you... ha ha ha

kinda like this though it doesnt show it well... remember what I told you.. it looks like crushed tin foil

ah, yes its got to be the accent.
thanks, i will try to get one tomorrow. Do they have them at checker or like Napa?

 

probably.. I got mine through US Tire and Exhaust but you need a commercial account...

try Napa or any other parts store..

 

Nathan are you able to weld right now?

 

That's kinda late to be asking someone to weld for you, isn't it?

 

like I said.. if my house was done, I could take care of it on the lift etc.. but I cant use the dealership stuff for anything other then my own cars...

 

another thing is that magnaflow tapers to 2.5" to meet up with stock dp? What are the chances that it will not even fit the new dp?

 

Get a 3inch flange with a 3 to 2.5 reducer.

 

to have it welded onto a magnaflow midpipe?


btw, on importimmage website it says that invidia dowpipe fits any cbe.

 

No, just use gorilla glue with some teflon tape, that'll hold up well..

btw, weld it of course

 

I will try to put them together and see if it works with crUsh gasket and LOTS of RTV.
