oh boy here we go! lol i had the alba exhaust when i first got my warrior (was already on it) and i didnt like it. the bolts stripped out and the threaded holes for the bolts are ****! also, i couldnt get the freakin core out to repack it because of the damn alba logo riveted on the can! im sure if i had abused it a bit i may have been able to get it out, like maybe by drilling out the rivets on the logo and trashing it. needless to say, i did not like the "alba" exhaust. as for the alba bumper, i didnt have any big problems putting it on. i just had to bend the mounting tabs out a little so it would slip into place. i didnt have to use longer bolts or anything like somebody else said on here. if that was the case, they either sent the wrong bumper or it just needed to be bent a little. now, for the tusk nerfs. damn good nerfs in my opinion. ive had mine for a while and they are still holding up. ive got some good gouges in them from rocks at chadwick, but they are holding up with no problems. i did have to re-drill some mounting holes for the ims pegs, but that is to be expected when using 2 different companies products. all in all, the tusk nerfs are great because you dont pay so much that you are worried about scraping them over some rocks and shitting a brick about it. just my 2 cents. later yall!
