Buying a new truck finally

Should have an 07 2500hd 4x4 CC in my hands next week. Going to replace the exhaust as its immoral to have a stock exhaust in my driveway (wife car doesnt always count.) You guys ready for the questions :D

I have read that one the 4.8 and 5.3 that a single 3" exhaust is better off than than true 2.5" duals. Does the same apply for the 6.0l, or should I go with the duals?

I have a set of LPP headers I bought for my 01 that never made it on, will they fit on the 07? The 01 was an lq4, I have NO idea which 6.0l is in the 07.

Last, who needs to buy a lifted 01 2500hd crew cab :thanks:

nice headers should fit

My 2006 Gmc 2500hd 6.0 was a true duel setup into the muffler and single out.

^ I think my friends as exactly like that also and his was a 2002.

True duals into muffler and single out.

Unless the 07 is a NNBS style those headers should fit.

it is a NNBS, wasnt sure since I had heard the blocks were the same, just didnt know if there was other interferences in the engine bay that wouldnt let them slide in

Nope headers wont fit. Justin tried to put some headers on his 08 with 4wd and the collectors exit in completely different places than for the NBS.

Alright looks like I will have some headers for sale, thanks for info
