Nice Flow

Posted on 12/16/2005 by Gary R. (Rockton,IL)

"I installed the exhaust on a 99 Silverado. It sounds awesome and went together easy. I would suggest welding the seems. My tail pipes were sliping down even though I had the exhaust clamps very tight. The only bad thing is the space between the drive shaft and muffler, only about a half inch on my truck. Great sounding system though."

The Thunder Down Under

Posted on 12/05/2005 by Michael M. (Tulsa,OK)

"First off I would just like to say that the overall look of the system is far beyond what I exspected. It tucks very nicely under the truck and totally cleans up the look of the truck from the rear. None of those stupid looking exhaust tips here fellas. The sound is very sporty with a very deep tone. At lower RPM levels it is real throaty sounding, but at 70mph you can barely here it, which is very good, so you are not listening to the constant rumble. The overall sound of the system is the best I have ever heard on a truck and all my friends will agree. Not to mention that I noticed a diffrence in torque and throtle response right after the install. The install is a piece of cake and was easily installed within an hour. I highly suggest this system to those do-it-yourselfer's. It truly is the Thunder Down Under."

Legendary sound/ tight fitment

Posted on 11/24/2005 by Ralph S. - 2003 Subaru WRX (Iron River,MI)

"The muffler really has that "Flowmaster" legendary sound. There is one fitment issue however, I had to grind a little on the crossmember so it wouldn't rub.I used car ramps on my garage floor, set aside two hours for install."

A bit loud

Posted on 11/24/2005 by James W P. - 2005 Ford F-150 (Arlington,VA)

"My order came through quite quickly and installed as easily as I expected. I am concerned about the noise level in my F150 Lariat -- at around 1900 to 2100 RPM, the resonnance gets too loud to hear on the phone or listen to the stereo -- may look to change out the muffler piece with something a bit calmer -- however my 25 year old son loves the sound."

I liked it but....

Posted on 11/10/2005 by Dustin L. - 2002 Dodge Ram (Gerlaw,IL)

"The system sounds good at low rpm and even better at high rpms, but the day after I installed it one of the clamps broke amd I almost lost my muffler. Other than that its a really good system, it took me longer to take the factory exaust off than it did to install this system. The only thing I would change on it is the tips are too small, and get higher grade clamps."

"I was very happy with the customer service at AutoAnything. Very informative and professional. I would definitely buy other products from them. About the system. I think it was made very well. The thing I am slightly disapointed on though, is the loudness level. I wish the system was just a bit louder. I have had people tell me the system sounds stock. I just wish it were louder. Is there an upgrade?"

CLAMPS SUPPLIED WITH THE SYSTEM

Posted on 10/24/2005 by Jim R. (Chattanooga,TN)

"GREAT SYSTEM WITH THE PERFECT SOUND. NOT TOO LOUD, JUST THE SOUND I WAS LOOKING FOR. INSTALLATION WAS SIMPLE, BUT THE CLAMPS SUPPLIED, WERE VERY MUCH BELOW MY EXPECTATIONS. GO TO AUTO PARTS STORE & GET SOME REAL CLAMPS BEFORE INSTALLING SYSTEM."
