I recently purchased a 2004 Suburban 1/2 ton. I installed a K & N cold air intake and an considering replacing stock muffler with a flowmaster. I am looking for better performance and economy, but NOT increased interior cabin noise. I travel with my wife and 3 kids, and do not want them complaining of loud interior cabin noise, especially when towing. I talked with a tech at Flowmaster, they recc. the 70 series big block II, but another tech said any of their mufflers would create an uncomforatble interior cabin noise. Any advice or experience with these mufflers on this truck? Thanks in advance.

Just thought I would share the following. I managed to get 13 mpg (according to trip computer, may be slightly overstated) while towing an 18' 3500 lb travel trailer about 550 miles round trip last week. I had the cruise control set at 55 mph. We have a 2005 Yukon XL, 5.3, 2WD with the 3.42 gears. The truck seemed powerful enough at higher speeds, up to 65 mph (particularly when drafting a semi). But it was only doing about 10mpg at 65, and the transmission constantly wanted to downshift and rev quite high, and the shifts were rather abrupt. By turning off cruise and just allowing the rig to slow down a bit on inclines, I could keep it in high gear and get somewhat better mileage, but at 55 it seemed perfectly content with cruise control on and rarely if ever needed a downshift. Don't worry, it was a very light traffic area (Hwy 287 in the Texas panhandle plains) and I stayed in the slow lane. I suppose I could have saved about 90 minutes round trip by doing 65-70 instead, but it's so much less stressful just slowing down a bit and not having to watch for cops, and never having to pass anyone else. Besides with three little ones, you have to stop for bathroom breaks so often that there's no point in trying to make good time. Just leave earlier and settle in for the long haul. This was our first time with an RV, and we loved it. It was a rental, and we'll definitely rent again, and probably go for something slightly larger. I suspect a pop-up camper would give much better fuel economy as it's obviously the wind resistance more than the weight. The guy actually has a very nice 31 footer that he said we could easily handle with the weight distributing hitch he supplies with it. It's about 5500 empty, 7100 max, which is near the stated max capacity of our truck. I'm willing to give it a try. So nice to just park and plug in and have a nice kitchen and bathroom and real beds to enjoy at the end of the day. |

I recently purchased a 1999 Tahoe that does NOT have a towing package included. I have an 18" pontoon that weighs next to nothing and was wondering if it would be safe to pull with the tahoe using just a ball. The distance being traveled is only about 5 miles down the road to the lake. I plan on getting a towing package soon, but we are going this weekend and I need a quick answer!!!
