Looking forward to picking up GT tomorrow to hear the new exhaust note. Power from the pulley change was very evident.
Borla Installed today
- Thread starter Awsum GT
- Start date
Whipple Superchargers did all the work and supplied the new pulley. They also reprogrammed the computer.

Yeah, I've got one.

I'm also thinking about installing the muffler. Love to know how much louder it is. Could you estimate it in %s.
I only installed the muffler. I'll post again after I have picked it up and had a chance to hear the difference.

I'd say thats about right. But it sounds nicely fat, full and deep when you accelerate, I like that.PILOTJPW1 said:

Had both, sold both
I have the headers and muffler...entire Borla exhaust kit, no cats. About $6k after installation. I'm told only 12 full kits have been sold. A very big job to install...they racked up 21 hours of labor (only charged me for 6 hours...very cool local Ford dealer.) Sound is amazing, and outrageously loud when you hit the throttle. It gives the idle more of a rumble, but the acceleration sound is insane. Too loud to drive around town unless you really baby it. Get on it and you will be pulled over quickly. My left ear was ringing for about 10 minutes after a run yesterday (I did a short short tunnel). I can't recommend it at all if you plan to drive on the street...it makes you baby the car. But on the freeway it is awesome.
I can't stress enough how loud it is past 4k rpm. I might have to go retreat a bit and just do the muffler kit.
I have 12,000 miles on the car now. No problems, runs perfect. Driven extremely hard. About 50% wear on my second set up rear tires...fronts still fine. By far the best car I've driven.

2005GT-
Thanks for the review. I wish there was a way to split the difference on volume between just the Borla muffler and the headers with muffler.

I am still glad I did the whole kit (headers and all), even though I have to baby the car practically everywhere except the freeway. Man, I bet I'm getting 30 mpg!!! (joke)
Too bad the muffler kit alone is not very loud...I am glad that info was posted because I doubt I would be completely happy without the full kit. Now I feel better!
I showed a friend the exhaust; he said that under hard acceleration my GT is just as loud as his NASCAR. Pretty wild (and fun!)

I am in the process of installing the Headers and leaving the stock muffler. I too want a better exhaust (louder) note. I am having the system Jet Hot coated so it may be a while before I can report the results.
And yes this is a time consuming pain in the %^$.
The only uncommon required tools are a specially GT modified automotive lift and an over-head travelling crane ( to remove the engine cover, if three helpers are not handy). :bored

Happy New Year ,again.
I finished the Header W/Stock Muffler installation. I am very satisfied with the sound. Very nice deep idle, apx 10 decibles louder at cruise. At WOT it sounds like Lemans.
My local Dyno shop is down for the winter, so no dyno results. I did not do this as a power increase but more for the sound. I would advise this mod. :banana

101 ,
after just reading the post of 2005 GT I think you can buy mine (at the dealer, arrived last week).. The Borla muffler might be just right...Soo many times they came after me in the Stradale (has always opened valves), that I think the GT with Borla muffler will be fine... let me know, 101 !
