i want to combine the coupe lower rear bumper to the sedan upper. i want the dual exhaust cut-outs. is there a way to mold them together? what kind of material would be used to do this? first off, what are the oem bumpers made of, polyurethane, abs plastic, etc...? i was told you couldn't use fiberglass and body filler on this because lack of adhesion. is this true? do they make some kind of resin/filler for polyurethane? i know fiberglass to fiberglass is no problem, but what about poly to poly? any imput is appreciated. thanks in advance

 

annnd why would you want dual exhaust cut outs?

 

for true dual exhaust of course

 

lol not to sound like every other member but I'd do some searching bro, the subject of true duals has been discussed alot (I think there was a new thread on it recently). your going to have to do some major work on your car because the spare trunk compartment runs in the way of the stuff for another exhaust pipe.
take a look under your car for yourself

but good luck to you, I'd really like to see what this would look like

 

nothing against you bro but i'm sick of everyone telling me the same thing. if you look at the threads i have started you would see the answer to you questions/comments. i have searched this forum FROM TOP TO BOTTOM about this subject and have been to autobody shops and yes, have looked under my car quite a few times. i have googled this sh*t too, and can't get an answer about this bumper problem. doing the actual exhaust is not the problem, its finding/making a bumper that looks halfway decent.

 

bump

 

i dont think it would look right... anyone good at photoshop?

 

i would try but i suck...ill still try tomorrow or something...

 

yes, photoshop...please

 

I know this thread has been dead for a bit but I thought I would give it a bump...

I believe the wald replica(wize) bumper has dual exhaust cutouts. It is made from fiber glass so you can modify it however you need to. Actually, you will have no choice but to modify it as it was originally made for the JDm market and has fitment issues... you can search it on here.

Even if you have already figured it out I thought this might help someone...
