Need a little anger

[Tledford321]

Want to make my '11 hoe sound a little more angry and don't really wanna spend $1000 to do whole exhaust system. Not real familiar on what manuf. are good or what I could do to achieve the better sound without breaking the bank. Any suggestions out there??

GM Performance Sport catback exhaust. Full warranty backed by GM, covered by insurance because it is OEM, cheaper than full exhaust, adds noise, and allegedly increases horsepower. If that's not enough, get a good CAI.

You could try the GMP exhaust like domin8 mentioned, or you go the route that I did, and get SLP tips & delete the resonator for about $120. It offers a slightly more "angry" tone, but I'm almost positive there is no performance gain.

This is my setup, before and after.
This is a link to the SLP tips with resonator delete. Notice that it says 2007-2010 Avalanche/Tahoe/etc... I'm not 100% sure that it will work for your 2011, but I don't see any reason why it shouldn't? Hopefully someone else can chime in.

Friend of mine just picked up an N/A ctsV.... he removed the mufflers and has it running thru the cat/s and resonator only...
SOUNDS INCREDIBLE....Mean.... Tight....with NO raspiness

Magnaflow muffler 12589, resonator delete, and volant or slp tips.

I'm very happy with my Magnaflow cat back system. Cost around $400. Added a nice aggressive tone to my truck with no in cabin drone. Slightly better acceleration as well. Here's a sample vid.
