I'll talk ya back into it.

First, any kiddies? If so, all bets are off. If not, here's what to do: Swap out CAI for stock box plus a little $$ with somebody. It will quiet down intake roar.
Second, swap out tires for Conti touring or similar touring type tire. Quiets road noise considerably.
Third, if you have a cannon exhaust, swap it! (duh)
They ain't the quietest cars on the road but those items will help considerably. A little dynamat in the hatch area goes a long way too.

That Teg will still be fun to drive, reliable for years, great gas mileage, paid for, etc. etc.

On second thought, where do you live? Maybe you sell to me.....bargain price, motivated seller. Your Teg is a piece of crap. Give it to me.
