I'm going more for sound than for performance, but if a cutout can get LS1's 10-15hp, how can a 4" exhaust make you loose power?!?!

Smitty's Muffler in Middleburg are awsome, cheap, and have all the big mufflers and pipe you'll need.

They have 4" out there? I'm probably going to order the muffler from Summit or Jegs. They're MUCH cheaper than I've found here in town.

The loss of low end power thing I think is usually atributed to part throttle power or feel. Not really WOT. I know when I didn my cutout for the first time on the T/A and when I ripped my full cat-back off the truck to see what it would do it felt like I lost throttle response and it took more throttle to get up to speed than it did without. That's my take

Yea, they do all kinda of crazy ****. They are a redneck family, but good at what they do. One of them put a built 350 in his wifes Astro Van, another put a Pinto body on a Toyota frame with 38" swampers.

They do alot of diesels out there too, so they have 4" pipe. They dont have a 4" bender, but they have all the angles and strait pieces for a full manderel system.

Hmmm, Banks has a 3.5" system but is it worth $1325?!!?!?
That does include a filter and shorty headers, though.

I'm convinced the more exhaust flow the more power. If any one disagrees fell free to try it. unbolt the exhaust and run it open headers.
