Guys i just got a used 2011 avalanche and i love it but i was wanting to put a cold air intake system on in and i was gonnat put your typical K&N on but i have heard that airaid is just as good and cheaper and i didn't know if is hould go that way or if there are any others out there i don't know about but the big thing is would i need a new exhaust system to help out the MPG cause i travel and hunt tons but i would have turndowns and i want it to be a deep sounding and sound really good not loud and in high school truck and i haven't had pipes in forever and i don't know which way i should go with them... Any help would be great guys cause i'm not getting much on other web sites and i'm kinda new to all this thanks though

 

Avoid flowmaster as all costs. I love my spintech not sure which model it is but it is really quiet at idle and when crushing but when you step on it it really wakes up. Only thing I don't like is that it makes my truck sound like it has a v6...but that's purely mental haha

 

Mean to say cruising

 

haha a v6 well i was looking more at magnaflow this time cause i've heard good things from them

 

It's up to you. Everyone will say something about this brand or that brand but as long as its not the stock muffler or a flowmaster then it's just fine. I'm on my phone so I cant see your location, but if you live in a state where they salt the roads, I'd consider having it coated or getting a stainless steel muffler to reduce the chances of rust

 

No no I live in the south so not much ice here but I think I'm gonna look in to the magnaflow but do you have any recommendations on a cold air intake system besides K&N cause of there price

 

I have a couple Bassannis and the are quite cruising, but when you open it up man it comes alive.

 

Put a drop in K&N air filter into your stock box and either make our own pipe from the box to your TB or get the Airaid setup.

Like mentioned above, anything is better than stock. Magnaflow would be a good choice

 

so should i stick to an airaid K&N or volant???? any others that i need to take a look at and anyone have a good website for some good deals

I have that and I have no complaints. I went from a drop in filter and stock intake setup to that. Feels a little snappier but probably mental there, but it sounds loud as hell at WOT which is cool with me. I have stock exhaust and I can hear the intake noise way over the exhaust.
