Description

The Straightflow 55mm Resonator is a straight-through exhaust resonator made from 409 stainless steel, with a 55mm inlet and outlet, a 30cm (300mm) body and a 90mm outer diameter. Straightflow lists it for sound control in custom and performance exhausts without restricting exhaust flow.

What Straightflow states

Straightflow says the 30cm body gives balanced sound reduction, helping to reduce harsh or high-frequency tones and exhaust drone while keeping a deep, clean exhaust note, and the 90mm body diameter gives enough internal volume for acoustic absorption without taking up too much space. The straight-through perforated core lets exhaust gases flow freely with minimal backpressure.

Straightflow says 409 stainless steel is widely used in exhaust manufacturing for its durability and heat resistance. It lists this resonator for 55mm exhaust systems, naturally aspirated engines, custom exhaust builds, sound tuning and drone reduction, daily driven vehicles and street performance cars, and recommends professional welding installation.

Fitment

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

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