I got under my new car yesterday to remove the restrictors and noticed something that has my curiosity piqued. i didn't take pics under my old boss to prove my theory, but i think ford has changed the design of the side pipes in later builds. I'm 90% sure that 0001 has a singe diameter pipe from the H to the tip that mounts in front of the rear wheels. The new boss has sections of tubing that taper down towards the tip with each section welded. I don't recall 0001 looking like that at all. I recall a bent section of one piece tubing. i also noticed this morning on the first drive of my new car with no restrictors that it is not as raspy and doesn't pop like 0001 did around 3000 rpm. Anyone have pics of their side pipes, especially early builds so i can satisfy my curiosity?

I would think that S197 could probably answer this the best.

So you expect others to post photos but you didn't take any? Did you take photos of the new one? If so why don't you post it so others can see what you are talking about. What kind of journalist are you anyway?

The photos of the LS which was mounted on its side to display the underside of the car has sections welded together. See this photo

Shane, haven't you heard? After #0332 Ford went with the new 4-cylinder engine to reduce cost and emissions.

Well, well...look at the big brain on Brad, I mean Shane. Another photo of an early 302:



There is a longer piece from the "disc" junction, then a longer flex-pipe and then a single piece, instead of the multiple welded piece, before it goes to the flat pipe.

I was right! that last pic is what 0001 had and the first one is my current car. I was going to take pics under mine for you wisenhiemers, i just didn't have a chance. was getting ready for my sons b-day. wonder why the change, i get it was to reduce the popping and raspy note, it was rather truck-like on my first boss.

That photo is of a pre production car. If yours was the same then it had pre production parts on it. Maybe they were using up what they had? I started a thread here back in January about the side pipes with photos and s197ford commented about it.

ShaneM

interesting. That second shot is definitely what 0001 has on it. like i said, not nearly as raspy and it doesn't pop like 0001 did around 3k. any of you other early build guys check what your car has under it, i am curious how many used those pre-production parts.

send s197ford a PM asking him to comment.

Big Vito

You had the discs out the first day, had it for a month and no pics? I call BS

ShaneM

doesn't matter to me any more, i just didn't know they were any different between cars until i climbed under my new one yesterday and noticed the difference.

Just checked mine (car 227 built Mar4) and it's like the first photo. I wonder when it switched?

Big Vito

Maybe number 2 or 4 or 6 could get us pics?

I'm pretty sure the car in post 5 is a pre production car and the car in post 7 was an early mule created for the August 2010 intro.

ShaneM

lol, it never crossed my mind to take pics under the car. Yeah, i couldn't stand how quiet it was with the discs in. after i got home as soon as it cooled off i pulled them out.

Big Vito

Ask the new owner for pics

ShaneM

dont need them now, that second pic is exactly what the 0001 car has. i looked at those parts when i pulled them to take the discs out of the first car and thought they sure did look hard to make. they were a lot lighter though. 0333 has the first pic parts.

Here's the thread I started on this months back.
