z350convert Posted September 21, 2015 Share Posted September 21, 2015 Thumbs up for Cougar Store . Mitz very helpful with advice and quick to deliver new box and resonated mid pipe. So I have a standard 2003 car with a Cobra back box and midpipe matched to "Roadtrips" 2007 Y pipe. Result, much deeper sound, very quiet on idle and nice crisp raw as power is applied from about 2500 rpm. All went on quite easily once nasty rusted bolts on the cat removed, nothing broken. Took just over 2 hours with a local mechanic. Car possibly a bit more torquey now but I might be imagining that. Good result and very pleased. Abbey Motorsport in Oxted also very obliging Neil Quote Link to comment Share on other sites More sharing options...
