Mufflers, which brand?

[anglia4]

When the mach gets here i'm thinking as a little bit of a summer project i might have a nudge at building an exhaust for it.

We are very resourceful people down here in NZ and i have access to all the required equipment and expertise.

My 5.0litre GTHO had Mac shorty headers, an OR H-pipe and flowmasters 2-1/2" pipes down each side.

What i am visualizing for the mach is standard headers, biff out the cats, 2-1/2" pipes, was gunna have a go at making an x-pipe to get some flow.

At the end of the day its a road car so its gonna be sound over performance, is the h-pipe or x-pipe the way to go for noise?

Also i was thinking flowmasters for the mufflers coz they are available here in nz but i could import the mufflers, what makes the best sound? I've heard mixed reviews about the flowmasters, and ive been told to go 3 chamber over 2 as the 2 chambers are drony

I liked my gtho noise as when i pushed it out to 5500RPM it sounded really crisp, sounded like a proper screaming V8 race car, alot of that was probably in my edelbrock heads though.

Reason for building something is that with the size of exhaust systems they are not economical to post to NZ, just too expensive

your honestly going to get a hundred different opinions about sound. try some utube videos or the link above thats a sticky. good luck i choose a mrt catted h-pipe for amore deeper sorta old school sound. and a sss catback no complaints here.

X pipe with spintech mufflers

+1 I love my SSS with an H pipe. Its affordable. I'd have gotten the borla stingers but too expensive. Your just gonna have to go to youtube and listen to sound clips because way too many personal preferences here. Or start asking some mustang guys around your local area if you can get a in person sound clip. Good luck

i agree everyone likes different stuff so you are going to hear different the true way to know what to get is go on youtube and find some exhaust that way. the top ones of my choice i think sound amazing is

Kooks LT's w/ x pipe and SLP LM1's
SLP full exhaust headers back
o/r h pipe with slp LM1's

those are my top choices i pick on exhaust

i run a o/r h pipe and bassani cb i love it but i wanted it louder so i'm putting on single chamber flows

go on youtube

Go with a set of Longtubes (ARH, Kooks, etc.) Xpipe and Borla XR-1's. The sound is pure sex.

found that one this morning on youtube, i reckon that is about the sound that i want from it. Would definately sound right chasing my dads shelby down the road

has anyone on here run original 40 series flows? do you get resonance in the cockpit?

I want my car to sound mean but dont wanna be deaf after a long trip at 65Mph. Perhaps Dynamat could help with that one though :ORANGE:

man its really what you want, if you like that sound go with it. if you run the exhaust out the back the smell won't be so bad, i wouldn't worry bout it. but just get what sounds good too you

Every muffler is going to have some cockpit drone around 65 to 70 mph is usually when you can here it. I just turn up the radio.

even with me havin a o/r h i can still hear it but its not even bad, i can talk normal to any one in the car and if i really don't want to hear the exhaust (which never happens) but i could turn up the music and listen to it like LS said

out of interest, what diameter are the standard exhause pipes on these things?

Also as i'm a mechanical engineering student and have just done a paper on heat transfer and fluid dynamics i might have a nudge at doing a bit of research and designing my own mufflers, Maybe not for the mach to start with, might try on another of my project cars.

[ASH302]

pretty much your exhaust pipe is going to be 2.5

They are 2.25" in diamater. For the 2005 model year, the diameter on the V8 GT was increased to 2.5", although I believe there was a point in the system that actually was pinched in to 2.25".

Good luck in your studies!
