I like mine, they sound clean and mellow at idle and cruise. But when you open it up good GRIEF they make the car scream!

 

What do you guys think about the pypes muflers advertised on this site forum on the left hand side???

 

well if you want some thump in the exauhst then you'll need to get a bigger cam, i would put some 3" pipe and glasspacks for an exauhst system

 

3" pipes will definately make it louder, but are WAY too big for that 289. 2.5" pipes are capable of supporting over 400hp from a 289/302 without being restrictive. 3" on a small engine will just kill off power pretty much everywhere except for very high rpm. I wouldn't put 3" on a 289/302 unless you were spraying a fair bit of nitrous or were blown

 

Didn't original 289/306hp Shelby's have 3" pipes? I am not sure...

Sorry - I don't have any video of my car.

It's interesting the the sound of a classic Mustang is an extremely important element to it's overall enjoyment.

I researched exhaust sounds for three months before going with Borla. It is exactly what I was looking for. No hollow rasp, no overbarring boom-boom-boom, no overcompensation, no interiorresonance

Borlas are a serious system.Listen carefully to the 2007 Mustang GT's. The are quite but have adeepbass undertone. That's the best way I can describe my sound. It doesn't wake up the neighborhood but when you get on it, the sensory imput is a rush!!

I bought these without ever hearing them on a vinatge Musatng. It was a leap of faith.

 

pity...i'd like to hear it especially with all you have completed now. i listened to their website clip...its so hard to tell on a pc what any of the systems really sound like. my advice to npg3 is listen to cars on the road. go to a mustang show and listen to cars with similar engine combos to yours.

btw, the original shelby's were at most 2 1/4. the 350R models may have had 3".

in my experience, smaller pipes are better for exhaust note. the gas velocity is increased giving a cleaner crisper sound...more v8 snarl, less deep boom...depending on muffler choice of course. you just dont need 2.5 or up from a 289/302 unless you are running silly numbers (power and revs).
