5 Stars   Bassani street mufflers, amazing !!
By on 9/28/2014
Let me start off by saying that like everyone else I spent a week or so in the evenings reviewing every axle back muffler out there and for me cost was not a factor. I look for form, fit, function and the I gota have it cool factor when I am searching for items for my projects.
After reading all the review and listening to every video out there, I was being swayed to the Ford racing GT500 mufflers like a see alot of people are. And I've heard these in person on a new mustang like mine and they sounded good. but I still felt something was missing in the note.
What I'm working with is a "new" 2014 mustang GT premium manual trans with 3.73 gearing that is bone stock at this point and below are the factors that lead me to choose the Bassani street mufflers.
1, There are not a ton of reviews out there like other mufflers but I have owned two sets of ex for two Harley's I own and from that I knew Bassani makes a 1st class product when it comes to my criteria. The unknown was the sound.
2, Because I will be having a supercharger installed in two weeks, I knew I wanted a full flow thru muffler style.

The install:
The stock mufflers were a pain in the a** to get off and part of this was due to having my car undercoated..I remember thinking I'm glad I don't have to put back on this can style mufflers !!!
The Bassani street mufflers went on extremely easy. Note: Bassani feeds the two main hanger rods into the hangers from the other side. Very smart !!!
After i got them in the hangers I just snugged the clamps. I held my fingers between the car opening and the end of the muffler to center it, tightened the clamps, repeated with the other side and crawled out to see what needed adjusted.
To my surprise they were perfect ! stick-out, center and the look was amazing.

Sound test:
I refrained from making a judgment until i had put 100 miles on the car and this is my conclusion
1. The note is incredible. The throttle position is everything ! it will roar when you want or sneak past the man when you need to.
2. idling is the best I've ever heard on a stock car with just a muffler change.
3. There is a little drone between 1900 and 2100 rpm if the throttle is held just right during light load on the motor...... I say SO WHAT ! if i got to hear that for 30 sec now and then to get the sound of these mufflers then so be it..
4. form, fit, function and the I gota have it cool factor... A+ , I would not trade these for mufflers costing twice the cost.

I will report a final conclusion after the supercharger is installed.

Yes, I would recommend this item to a friend!

5 Stars   The finest axle back money can buy
By on 11/6/2014
Purchased this item along with a few others as the first mods (jolt carbon fiber intake, oil separator, Barton shifter and 2 post bracket, sve tune) to my otherwise stock 5.0. I must say after watching hundreds of videos and reading through an equal amount of reviews I couldn't be happier. None of them do this set up true justice. There is nothing equivalent to hearing it in person. Absolutely perfect, no rasp or drone. Just the right amount of loudness. Definitely can't wait to hear it with the pypes off road h and stainless bbk tuned length headers I'm getting next.

Yes, I would recommend this item to a friend!

5 Stars   Awesome Mufflers... one downside
By on 9/23/2014
Image uploaded by Carlos B. So I've had them for a couple of weeks now and they sound amazing ! Absolutely no drone! They look great and sound even better! BUT... The tips don't line up exactly right with the mufflers. At least they didn't with my car, they kinda touch the curve around the tip but if that doesn't really bother you then go for it!! I have a 14 5 oh btw so they might fit perfectly on an 11-12.

Yes, I would recommend this item to a friend!

5 Stars   perfect sound
By on 4/14/2014
Delivered very quickly, was tricky getting old mufflers off. Install much smoother, found it much easier to remove rear hanger assemblies and preinstall on mufflers, then bolt back up to underside of car. Very happy with sound, no drone, not too loud, great tone. Tips are top notch.

Yes, I would recommend this item to a friend!

4 Stars   Great sound
By on 2/25/2015
Was a little disappointed in the mounting of these mufflers not sure if the mount rods got bent in shipping or what but I had to bend them so they would fit in the bumper openings and not be hitting it. The sound is great specially when you hit the go fast pedal with cat deletes.

Yes, I would recommend this item to a friend!
