True Duels with Stock Manifolds What I have is an A4 2002 Z28.
What I want to do is keep the stock manifolds and have true duels with an X-pipe, probably 10-series Flows, dumped before the axle.
1. How much HP would I gain if I put long tubes on and is there any difference in the sound? I hear the stock manifolds flow pretty good.
2. Should I keep the cats? If I take them out, will I loose any torque? How much rasp would there be?
I want this to sound bad ***. If I can do ot without headers, that would be great.
Let me know what you think.
Thanks,
Dave

and wishing you had. You do not need nor really want cats with duals, duals have no rasp 
Sound will also be more what you are looking for without cats, as well as more power. Why do you not want headers? There are some great buys nowadays on longtube headers!Look into pacesetters (or Jet-Hot, etc if you have more $$ to spend) and TSP's rumbler X.

definitely get long tube headers. you're nuts for not wanting them. go to ls1sounds.com and listen to some clips with true duals with headers, and you'll understand why. 
true duals with lt's

How difficult are LTs to install and which ones? I can't go all out and spend a lot of cash, but I don't want waste any money on poor quality.
