Default Down pipe

I've been doing some research but can't seem to find any down pipes for an lb7. Are they not as smashed in as the later models or what? Will an lbz pipe fit?

lb7's are a huge paint in the butt to remove in the first place, and yeah they're smashed like the other dmax engines. they have a big ugly flange to bolt onto the turbo instead of a v-ban clamp so a lbz one wont fit.

Well the transmission is coming back out today. We were just going to change the down pipe while we could get to it. Does anyone make a pipe for an lb7?

X2 ... The RDL downpipe is a very good upgrade.

ppe makes a decent downpipe upgrade that isnt hard on the wallet, if you can get the old one out.

PPe makes an awesome downpipe for the lb7. getting the old one out is a different story

ppe makes a good lb7 downpipe. diesel performance carries them and they are pretty affordable.
