Borla AKA GM Performance Exhaust

[amrg]

Just got a new exhaust installed on the Alpha, thought Id share it here.

Got a Borla, which is also the GM performance exhaust, directly from Borla. They have a clearance sale and I couldn't find any cheaper ones on ebay. So far I love it. I've only driven for a short period but I'll get around more tomorrow.

Here are pics of the package and install

The old thing removed



New shiny parts



Finished thing



Not a very clear picture, but it kinda reduced rear clearance at the back significantly! Not that it matters, wheeling here is basically on soft sand and loose gravel




I'll try to post more pictures tomorrow, somewhere in the desert, a place suitable for an offroad truck
I did the install in a custom Jeep shop btw, feels weird to be surrounded by so many lifted Jeeps when they think of me as an enemy

Sounds great! Gives the truck the presence it deserves to be honest. At the low rps (cruising speeds) barely noticeable, regular driving there is a humm inside the cabin and a louder humm outside it , not loud. Stepping on it its great. Revving the engine at standstill sounds really loud and rumbles when u depress the gas pedal , overall I love.

It gave a performance improvement too. I noticed on full throttle the shift between first and second is now jumpier, and I actually measured acceleration and compared to before. Not that it really matters, since its not like Im gona be drag racing, but I like numbers coz they tell me if I improved or not. Stock with me and a friend in the car I got 0-60 of 9.2, now with k&N and the cat back its down to 8.3!

Any drone ? Drone is a humming, vibrating sound that kills hearing over time. Magnaflow claims no drone. Local Muffler Shop might be my route .... Suggestions? Thxxxx.

Ive driven a 5.7L Hemi Jeep Grand Cherokee and a GMC sierra 1500 single cab, both sound louder at cruising and regular driving inside the cabin. Cruising below 2000 rpm, I cant notice any sound inside the car. Above 2000 you start hearing inside the cabin, but its nothing annoying at all. If it makes any sense, Im able to have conversations comfortably with my friend or on the phone without having to bring up my voice, or feeling there is something protruding and bothering me.

Check this clip, http://www.gmaccessorydealer.com/exhaust/exhaust-hummerh3.mp3 , its for the I5. What I have is the last one played in the clip, offcourse on the V8 its deeper and more agressive.

What's a better best sounding/performing/NO DRONE Cat Back Exhaust for the Alpha H3: Magnaflow or Borla/GM? Honest, direct answers please. Thx.
