Who will be the first exhaust manufacturer to try and replicate the orgasmic sound of the LFA and apply it to a an exhaust on the ISF , who would like this

this isnt exactly in the realm of possible.

I don't see why not ? Can you imagine

because the sound the LFA makes is a byproduct of it having 10 cylinders, being 4.8L in displacement, revving over 9000rpm and having the rotating mass of a feather. that is why it cannot be done.

Why can't the IS-F rev safely to 8 grand + like the M3? Is that why the M3's fall apart after 60K miles?

The F430 features a 4.3L V8, whats your point

you have got to be kidding me.

i was going to split this up, but this one answer should hopefully address both of you.

engine displacement directly effects how high it can safely rev, without extreme modifications. the reason a f430 sounds like an f430 is because ferrari uses a FLAT-PLANE CRANKSHAFT. this enables it to rev much higher and faster then a CROSS-PLANE CRANKSHAFT like the one found in the 5.0L lexus v8. i'd be willing to bet the lfa 4.8L v10 has a flat-plane crank shaft. and unless i am mistaken the m3 has a cross-plane however it is able to rev so high because it has a small displacement, 4.0L.

therefore the ISF 5.0L v8 can NEVER produce the same type of exhaust note that the lfa or f430 can.

To me, there's nothing like the rumbly sound of a V8. Again, to me - IMHO, it sounds much better to my ear than the nervous*high strung sound of the LFA or other exotic automobiles. But, then again, I've always felt that way. When I was young and rode a motorcycle, it was a Harley Davidson. I guess I'm not alone because Harley patented the offset crankshaft mechanics that went to create that unique Harley sound.

IMO, the ISF sounds just perfect. Mine has a slightly modified sound due to my exhaust mod. I luv it.

Edit - just to add, I'm also a BIG NASCAR fan, and I have no love for open wheel racing. I'm sure the sound experience has a little to do with that. Last year I went to Kannapolis, North Carolina to visit an old friend. This town just happens to be in the heart of NASCAR country. To me, there is no sound like that of a Cup Car firing up. The ground rumbles and well, to me that sound is beautiful.

And yea, you can't make a silk purse out of a sow's ear, just like you can't make a torquey V8 with 371 lb. feet of torque at 5200 RPM sound like a bumble bee V10 with 354 ft. lb. of torque at 6800 RPM. But, again, IMHO, why would you want too?
