Taken from Daddysscp.com: This is the original, legendary product build by Hayward and Scott. Famous for providing the exhaust systems that have taken Ralliart and Tommi Makinnen to the top of the WRC list, year after year. Hayward and Scott have provided similar success to Nissan drivers in the BTCC. In time gone by, they were the company chosen to design the exhaust systems for the Ford RS200 Group B rally car and are still a subcontractor to Ford Research, Lotus and Rolls Royce for prototype work. When the last 3 original Ford GT40's were finally assembled in 1999, Hayward and Scott were selected to provide the exhaust systems. Owning a Scooby Sport exhaust is like owning a little piece of Subaru performance history. DP is wrapped. Sold.
A couple of clips at BIR, turn 10: http://www.solera-restaurant.com/BIR10.divx http://www.solera-restaurant.com/BIR10-2.divx Was bought directly from Hayward & Scott. Original invoice:
This is a very nice exhaust if anyone is interested! I have it on my 02 WRX and love it! Not loud at idle but screams very nicely when opened up! The sound is the best out there!! Just thought I would try to help you out, I love my scoobysport!!
No, 2.5". I still made 352whp and 374wtq on the Mustang dyno at RS with it and a 20g. I switched to a 30R and bought Dream's Invidia exhaust.
