I have a 2006 Silverado 2wd that i'm considering adding a K@N intake and a Flowmaster Dual (not true) exhaust to help with fuel economy...its roughly $700-800 to add them...does it really make a difference with fuel economy? Worth the cash?

 

That is a little pricey!! The K&N set up should only cost bout 240. The exhaust should only run bout 260. And those are full price. It is worth it as I mean that it will pay for it self. You will get an extra 2-3 miles per gallon. After putting it on, dont think you will notice that much of a difference right from the get go. Let the computer adjust to it, that will take a few days. You will notice that the exhaust seems to get louder and perform better.

 

Do the calculations on how far you will have to drive on the current fuel prices to make up that difference, what you will find is that it will take ALOT of miles

 

Where you finding a flowmaster dual exhaust for 260??? I found a cheaper K@N but not a cheaper exhaust...

 

I went to a shop that already had the set up. But I got the super truck exhaust. It exits in front of the tire.

 

Oh i see... want a dual exhaust exit out the back..maybe that's why its a lil more... anyway thanks for the advice...hopefully i can find it for cheaper

 

For a good bolt on, this is good...http://www.autoanything.com/exhausts...0A3035327.aspx

 

Hey thanks for the prompt responses...i enjoy a quick response...is the bolt on a simple job? Sounds like u just cut the old system off and then bolt on the new one? Is there any welding and fabricating crap? I just want the dual out the back with a nice tone and i really liked the way the Flowmaster sounded...do you know the difference between the 40s and 20s??? I see people talking about it like "oh yah its got 40 series" or something? Thanks for all your help

 

I would go to a muffler shop before I did another bolt on. And I bought my K&N CAI for $230.00 shipping included. Look on Ebay. There are other CAI out there too. For those prices does that include the instalation charges? If so that is way too high. CAI took me 30 minutes. Catback system a day after drinking and goofing off... plus having Stainless Steel tips welded on at a muffler shop.

 

Its all bolt on. There is a flange with 2 bolts that connects to the lead pipe to the muffler. From that flange to the back is all replaced. A 40 series is a loud 2 chamber muffler which is the most popular choice. A 50 or 70 and it gets quieter as it holds more chambers. Check this out.
