Ford Repair: lincoln 5.0 exhaust, lincoln town car, hooker exhaust

Question
I have a 1989 Lincoln town car with a SEFI 5.0 base engine in it. I want to put headers on it but I can't find any company that makes them for that vehicle. Do you know of any company that makes them? I am also putting dual exhaust on it. This car originally came with dual exhaust with an h-pipe, but the previous owner put single exhaust on it. I am putting the oem h-pipe and tailpipes back on it but I don't know what mufflers I want. I like loud exhaust and I like to hear the engine run. What mufflers would you recommend for more power and a nice sound?I know walker makes offset glasspacks to fit in place of the oem mufflers but I am worried about back pressure. The oem pipe size is 2in. Any info you can give me would be helpful. Thank you     P.S. Would I notice any increase in power over the single exhaust?

Answer
Hello Sherb, Since your Lincoln has a 5.0L look at headers for a mustang because they are the same engine. You'll have to look a your clearances where they go down then a exhaust shop can help for your piping and manufacturing of it. Flow master, steeda,gibson,hooker exhaust and headers also make performance mufflers check them out at their web sites. Good Luck and Hope this helps Thanks Tony
