A cat-back built for your car, not an average of everyone else's.

Useful sound descriptions include when the car should be quiet, which engine character should remain audible and what behaviour is unacceptable. A daily motorway car needs a different solution from a weekend car even when both owners ask for a deeper note.

Videos of systems you like can help, but recording devices and playback speakers change sound. Pi Motorsport uses them as direction, then specifies the physical components around the actual vehicle.

A system has to clear the body, subframes, suspension and heat-sensitive components while still allowing for engine and exhaust movement. Hanger position, joint location and tube route are therefore part of durability, not cosmetic details.

The retained front section is inspected before fabrication. Corrosion, previous repairs or an unsuitable connection can change the sensible system boundary and should be resolved before new work is attached.

For long-distance and premium road use, cabin comfort matters alongside exterior character. Silencer volume, resonator strategy and the position of sound-control components can be used to retain a strong tone without making steady-speed journeys tiring.

Classic vehicles often need extra attention around floor clearance, axle movement, fuel systems and period-appropriate exits. A custom system can respect the car's appearance while improving fit and serviceability.

Pi Motorsport's workshop is in Birmingham, with its central location making specialist work practical for customers travelling from London, Southampton, Bournemouth, Manchester, Liverpool, Newcastle, Scotland and elsewhere in the UK.

Travel should be arranged only after the vehicle brief and likely workshop window are confirmed. Complex or corroded vehicles may require an assessment before a final fabrication booking.
