Description
A passenger up pipe for twin setups
Wehrli replaces the thin, leak-prone factory up pipe with a heavy-duty 2 in. pipe TIG welded from 11 ga stainless, with a stainless bellows that resists cracking.
Wehrli says the larger, better-flowing pipe helps spool and lowers exhaust temperatures.
This passenger pipe uses sweeping, gentle bends with no clearance dent, for twin and compound turbo setups only. It will not clear a conventional single-turbo downpipe behind the engine.
Who it's for
LB7 owners running a twin or compound turbo setup.
