I always make my own exhausts. That way you have compleat control over sound/loudness and legality lol

Gibson/Magna Flow both have bolt on kits. Or take a trip to a local shop.

I dont recommend a dual exit kit on a smaller displacement engine. You might end up losing your low end torque from the lack of back pressure. You would be better off with a single exit kit for a true power increase.

You could possibly go dual by either having the over axle pipe split into a Y with a smaller diameter tubing - I would not go above 2 1/4" tubing. Or you could use a singe in dual outlet muffler - again dont go above 2 1/4" tubing otherwise your bottom end power could suffer

You are probably going to find most aftermarket companies only offer a single exit kit.

The majority of your backpressure is coming from the cats. If you retain the stock cats... do what you want to. You won't loose any bottom end.
Now if you have removed them... I'd agree Brad.

It'll work. Just understand that free-ing up the exhaust raises the TQ curve. So.. instead of max TQ at 3200rpms it'll more likely be up around 3800 rpms.

That doesn't sound like much.. but considering that in daily driving your operating at idle to 3000rpms it can be a noticable drop in power.

It's not as big a deal as some will say. Just know what to expect if you remove the cats.

You wont "lose" torque from going straight pipe or dual exhaust, you make more High RPM power over a muffler/cats, but the power bad shifts to higher RPMs, making it seem like you lost power.

I got the gibson sigle tip cat back exhaust and it sounds good and could tell there is a power gain and with my k&n i had a good mpg gain. with the gibson exhaust it sounds beefy but isnt annoying driving on the hiway

I'm always for going to a shop and have it all done. It usually ends up cheaper than going with a kit. I got my muffs(multiple...i've had alot of muffs on my truck), and had it hung for $150. That's just single out.

This looks pretty swell......with the option of adding a muff and tips....or running straight piped....
