Magnaflow, 2.5 with an Xpipe, Had Flowmasters on my 70 Monte Carlo and hated the drone sound.

researching mufflers Rob? By the way, I would want to know how loud, or how much resonance each of the mufflers had at 1800rpm where they all tend to drone a little bit (or a lot).

Cool!

Now which one sounds the best? I don't mind giving up a few hp for a better sound.

I hear that but it is totally subjective. Flash recommends straight pipes. :unibrow:


In between searching for Ford GT seats :rofl:

Always researching each piece to try to avoid doing any one thing twice.

I agree on the drone. I'm thinking Borla stainless right now, maybe even a secondary resonator out back by the fuel cell, but we'll see.

I agree on straight pipes... and GT seats shouldnt be THAT hard to find...

edit: took me 30 seconds.

Thanks for posting that. Anything to help get him off my back is much appreciated :rolleyes:

Rob, I would suggest you catch a ride in my car with Magnaflows, or Gregg's with Borlas, but those are both LS powered cars and an old school Ford would sound entirely different. Personally, I would try and find out what a set of Bassani mufflers would sound like. They have perforated chamber walls, but I think they also have a straight through passage. They might give you a nasty old school sound with a twist. They made the wimpy little 4.6 3V in my old car sound downright mean too!

Matt

I can find anything in 30 sec if $$ is no object. :lol:

I don't need a muffler to enhance the sound I need one to tone it down, remember this isn't an LS it doesn't need help sounding like a real motor. :rofl:

Mufflers are like wheels so many choices and in some ways it is very subjective. The db figures I posted only tell you level of sound. Also the hp and torque difference in the top tier is negligible.

I had already seen that post on the GT forum but read it again the guy decided he wanted to keep the seats. I'm still stalking you buddy. :D

dude you have a Torino... Clint Eastwood money!

teehee
