Throttle body get trashed on the inside from the breather behind the plate. Some good TB cleaner and rags not only cleans it up but helps the TB seal better.
 
"Noise" is relative to the cost of your catback. Older is also a relative term.

I don't remember an 89 octane setting for the Hypertech. Was either regular or premium for the programming. So do you have it set to regular and use 89 or premium?

Hey there.. I have a 2004 GMC Sierra 1500 PU and I am wondering if these trucks are prewired for the outside rear view mirrors with the LED chevron turn signal indicators. I want to replace my stock factory mirrors with factory mirrors off a suburban of the same year that has the mirrors with the LED indicators. I don't imagine that I would be lucky enough that this is a plug and play upgrade, and if not, does anyone have wireing diagrams to assist me in making this upgrade? Thanks alot for any and all help. BTW: my current mirrors are heated. Thanks again.

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.

Best canopy for Sierra/Silverado 1500? by m1kep

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?

Outside mirrors too wide by jacmyoung2

My 09 Silverado 1500 is a bit wider than the 04, I have to told my mirror to get through the garage door each time.
 
Do any of you know if the optional camper mirrors actually extand out less when fully retracted? Or if there are other optional mirrors out there I can consider?
 
Thanks in advance.
