1992 500SL, 2009 C300, 1998 Skyline GT
straight pipe 2 1/4 ending in a flowmaster 40. its loud proud and quick although not as quick as when i had my pipes cut after the cat. it has nice back pressure to save my breaks with engine deceleration. its a single pipe for now. going to add the second pipe with an x pipe maybe 2 x pipes.
