What Straightflow states

Straightflow says the 300mm (30cm) body gives effective sound dampening without significantly increasing backpressure, and the internal star-type perforated core improves sound absorption while allowing efficient exhaust flow. The 90mm outer diameter gives enough internal volume for improved acoustic control.

Straightflow says the aluminized steel construction gives resistance to corrosion and heat for daily driving and performance use. It lists this resonator for 55mm exhaust systems, custom exhaust fabrication and universal exhaust modification projects, and recommends professional welding and installation.

Fitment

This is a universal part, so there is no car list. Check your pipe diameter before ordering the Straightflow 55-40Z Resonator.

This resonator is welded into the exhaust, so plan the job with your installer. If you are asking us about the Straightflow 55-40Z Resonator, quote the supplier code so we can match the exact item.
