Mine is the Yodude, which you can get with magna flow, dynomax or flow master. If you are not going to get an intake you may want to go with the flow master, because it is louder than the others but softer without an intake.
Go to the page
Then go to merchandise, then yodude intakes and exhausts. It is around $330.00 for a dual made out of the same material as the factory one. Stainless steel is more expensive and won't rust from snow and salt.
Go to the same link, and go to performance, then exhausts. There is a link to the Borla site. It has a nice sound but is more expensive than the Yodude.
I guess I kind of push the Yodude becuase his owns a Cougar and is a member of the national club.
Also, there is a pace setter. I don't have a direct link, but it is the least expensive and I am told they sound Ok. Some people have had them since 99 and no problems, while others have gotten ones that have rusted.
I tend to agree with you on the style. To each his own. When I put the hood scoop and rear spoiler on mine it was aftermarket at the time. 2000-2001 special editions had them stock. I have found a German ground effects kit that I am going to put on my car. I think it has the best lines with the body. Attached is a pic of the kit. I have put a strut brace on the front and have Euro Cougar SVT+ style struts called ST200 struts and recently bought a 22 MM rear sway bar. Hanling like a dream!!
