#140 of 169 Re: 2008 exhaust system [powderal]

The new exhaust on the LMM is designed to cool the exhaust when the particulate filter burns off the soot that's collected (this happens about every 400 miles or so). It brings in fresh air to mix with the hot exhaust. The exhaust temps in the filter can get quite hot during this burnoff (upwards of 600º C, tailpipe temps about 1/2 that), so I would think twice about removing. Moving or bending upstream of the jet-pump (weird-looking tip) shouldn't be a problem, but I wouldn't cut it off.

My Sierra has the 4.8 LS engine, & I put a set of S&S full length headers on & it really brought it to life. I've been averaging a little over 20mpg driving to work. I have a friend with a 4.3 V6 in a Malibu, & he also has S&S headers, & the headers definitely perked up his V6.
#143 of 169 Best canopy for Sierra/Silverado 1500?
Nov 11, 2008 (4:05 pm)
I've looked at both Snugtop and Leer. Leaning towards Snugtop XV (xtra vision). Does anyone have this on their truck? Satisfaction? I would get the Snugtop Super Sport but I've read framed windows on the XV make a stonger shell. But I've also read the sliding windows are much easier to break into. I don't have dogs to haul around so ventilation isn't critical. Do you really find the sliding windows useful for other purposes? Any advice appreciated. Leer fans out there?

I'd like to put the wide field mirrors on my 2001 Chevy 2500 HD. I don't have power mirrors right now. Can I get them just manually operated? Thanks for any info.
