Run them both down the passengers side. Then bring your Passengers side pipe over to the drivers side exit. This will keep both pipes close to the same length, since your driver side pipe crosses over to the passengers side under the oil pan. You want to keep both pipes as close to the same length as possible, with as few bends as possible. Glass Paks will give you the "popping sound" that you said you don't want. Flow Masters will actually give you better sound and more power. Get the bumper clamps from the muffler shop, if you cut your bumper, the chrome will start flaking, then rust. If you can afford it keep the CATs. Remember the last time you were sitting at a red light breathing the guy in front of you exhaust fumes? Besides, Emmission testing or not ...removing you CATs is illegal in every state.

The 3" body lift is the best route though, and can be hidden with 33" tires if you are still running the stock 31's.

Also, Flow Master makes a 3 chamber 3" in dual 2.5" outs, if you want to go that route.

The problem I see with the 4" single collector pipe is that you will have very little or no backpressure. Good for highend RPM's, but you will lose lowend HP and torque. Just adding headers will do that to some extent. I'm like you and still looking for a setup that I can live with.

[sweepersrgr8]

Your stock setup should have a 2 into 1 collector(Not a "y" pipe, a box type deal), that goes into a 3.5" pipe, then into the CAT, then 3" out of the CAT.

If you decide to not go with TRUE duals...this Cat forward system will be fine, and save you some money. Then use the single in, dual out Flow Master.

Nothing beats the sound of full length headers, but there are shorties that will bolt up to your existing exhaust.

If you don't have this setup on your truck...ask around, someone will probably give you theirs.

If you go into a single pipe, you will not have to go that big. The volume capacity of a 3 inch pipe should be well able to handle it. When you double size,you quadruple volume.

Good luck,

Summit Racing has some shortie headers that some folks are using. They're not too expensive, and do bolt up to the stock y-pipe and cat. Only problem I've heard of with those is changing spark plugs will be a bear.

[sweepersrgr8]

NO. They will bolt up to your heads, but interfere with the firewall on the passengers side....If you dont mind beating your fire wall in a little to eliminate the rattle, they will fit.

Call Summit direct ....they have our shorties in stock, or can get them. Don't go with the equal length if you don't want to spend all day changing #4 sparkplug. That is the only one that is really difficult. A long wobble extension and an universal will get the others with ease.

is your truck EFI? if it is you need the h pipe to mount the O2 sensor. As for the flow master I have them and if you don't like to hear your radio they are great!
