I have talked to a number of guys who have got the 2-into-1 exhaust setup from BC Broncos & absolutely love it. Good sound & the performance is nice too. I run a dual setup with a very old set of Thrush Turbos 2" outlets & it is a good tone, but it doesn't breath as easy as I would like.
Oh I hate the bc exhaust! I have a 75 eb with dana 44 front axle
#1 they run under the transfer case first mod you have to make too increase offroad clearance run it on the side and around transcase
#2 my 75 dana 44 drive shaft hit drivers side exhaust, have a big dent in tube even with 5 inch lift
#3 the header too exhaust tubing supplied clamp never held on either side, finally clamped with regular exhaust clamps
#4 no turn down is supplied so it melts your ebrake housing another cost
#5 so loud my four year old son and I have too wear ear protection for any thing longer then a 10 minute ride
#6 when I purchased, passenger side did not fit , had too modify, but a call to them and they sent me a better part (thanks for that bc broncos)
#7 it cost too %^&*%$# much for what I got
I would not recomend and will replace When $$$ decide too jump in my wallet
Oh if you get it wire tye the header bolts too, once they are set...
Thats all I can say
