A manufacturing process to add a deflector (10,22) in a motor vehicle exhausts line comprising a collector, an inlet pipe (2), an exhaust converter (4) and an outlet pipe (6) connected in series; the inlet pipe further comprising a wall; the deflector (10,22), located upstream the exhaust converter (4) and " more or less " transversal to the gas flow, creates turbulence's in the gas flow, " improving " the homogenization of the exhaust gases prior to enter in the exhaust converter (4); the deflector (10,22) comprising an elongated member (12); the manufacturing process is characterized in that it comprises the following steps:
- piercing the inlet pipe (2) with one hole of similar dimension to the member's cross section;
- inserting the member (12) from the outside of the inlet pipe, through the hole;
- fixing the member to the inlet pipe. |
