Edmond: I came here to study motilium 30 mg bu The current V8 engines feature a redline of 18,000rpm, have two exhaust pipes serving four cylinders each and no restrictions to the exhaust system thus making them some of the loudest vehicles on four wheels. However, for next year’s V6 engines, they’ll be a single exhaust pipe with all six-cylinders feeding into it. Combine that with a lower 15,000rpm redline and the typical lack of noise developed by turbocharged vehicles and you essentially have the differences between the pair.
