2. Check the following:
a. Exhaust canisters (A) and bellow tube (B) for dents,
cracks, and wear.

3. Check the three band clamps (A) securing the tubes in
between the two exhaust canisters.
IMPORTANT:
Do NOT change exhaust canister type, piping sizes, or
exhaust configuration. Contact your Dealer for proper
replacement parts.
4. Inspect the area around clamps (A) for breakage, cracks,
and rust-through.
IMPORTANT:
If exhaust is leaking, tighten clamps to 12–15 Nm
(9–11 lbf·ft). If it is leaking at the band connection, replace
the seals. Contact your Dealer if exhaust leak persists.
5. Check the tubing for dents or crushed areas.
IMPORTANT:
Dents or crushed portions of any tubing create exhaust flow
restriction and increase back pressure significantly. Even
relatively small dents will cause decreased fuel economy
and increased turbo wear. If dents are relatively large,
increased bearing and cylinder wear will occur due to
increased exhaust temperature.
