The Seca sports exhaust for the BMW M3 provides great tonal quality with a much fuller sound at low rpm and rising through the revs to create a louder howl from the V8. At low rpm you will get a deeper fuller more throbby V8 sound yet the pitch of the exhaust note begins to change as the revs increase. The M-Power engine is highly strung, as such it has a much more racey sound, with similarity to the Ferrari 355. All Seca’s are made from grade 304 stainless steel, are a bolt-on / bolt-off system and weigh substantially less than the original system as well as providing a noticeable bhp increase of around 13bhp.
