hey you might as well put some upgraded uppipes on while it's out. i just had to replace mine last weekend with the cab on......and it sucks. the stockers tend to leak pretty bad, pretty often.
I just did some not to long ago on a customer trucks. I was B@$ch about doing it and after i was all said and done it only took me 3 hrs. I cant even get the cab off in that short amount of time.
To the OP looks very nice almost to nice to put back in.
