okay heres the deal i got a five in stright pipe now under the whole truck but i was wanting to run a single 5 inch stack out of the bed my truck is a 2001 4x4 qcsb and the other day i was under it looking at it and i was wanting to know if i can run a five inch pipe up trough the bed and have clearnce between the bed and the bed crossmemeber the stack will be on the passger side and also i will be doing all of the fabing myself so should i try 5 inch flex pipe or weld everthing what would be easier???and aslo if any one has any pics that would be great thinks!!

 

You'll need some flex pipe since the stack will be secured to the bed. I'm running a single 6" on my 2nd gen...look in my gallery. Sorry, no pics from underneath.
