So I took the gamble and recommended the B.C. Broncos 2 into 1 exhaust kit for my brother in laws Bronco. The kit states it is for stock engine, transmission and t-case only. My brother in law has an NP435 in his Bronco. I finished installing the exhaust today and I'm very happy with it. If fit perfectly and sealed up on the first shot. I ended up adding some pre bent pipe to extend the exhaust to the back of his Bronco as the kit only gives you a turn down. The turn down is my only gripe with the system as it doesn't fit the muffler. Not sure what happened but it was clearly meant to fit it. I wouldn't be surprised if Magnaflow changed the output size and didn't inform B.C. Broncos. Anyway, I just figured I'd post this in case anyone was on the fence about buying the kit. The engine is running so much better now, which is a very nice bonus.

I have bc 2 to 1 as well with wh headers and it added some great torque.. fit well with np435 as well

Same here. Had to do a little fiddling with mine because I used the huts headers, then went to house of mufflers and finished off the rest. Sounds awesome though and definitely improves some power.

Like the set up... Gonna run it on the polished turd as well
