- Internal x-pipe design combines crossover and muffling in one compact unit
- Twin inlet and outlet configuration for dual exhaust systems
- Space-saving solution when separate muffler and x-pipe won't fit
The str7750-409xp is a universal twin 2.5" megaflow muffler with integrated x-pipe construction made from 409 stainless steel. This compact unit measures 228mm x 127mm oval with 406mm length and features twin 63mm inlet and outlet tubes. The internal x-pipe design allows crossover flow between banks while providing sound attenuation in a single component, making it ideal for installations where space constraints prevent using separate muffler and x-pipe components.
