GT takeoff mufflers man vs auto

Being a Fox tuner and one of mine has a Kenne Bell on it I didn't take this car seriously at all. I sold one Fox to a good friend who begged me and I was looking at Maximas. My wife told me to just get another Mustang since I haven't ever kept anything around long if it wasn't a Mustang and I didn't want to commute in the K/B Fox.

I got the CAI more for potential MPG gains than anything else. Only the fact that it was $95 shipped and is much higher quality than expected is the only reason I got it. $200+? Not happening.

My biggest gains came from this weekend adding a Diablo Predator. This car will chirp 3rd gear more than half the time now and that was NOT expected. Maybe the combination as a whole made this possible. It's an automatic also.

Do I take the 4.0 seriously now? hmmm, well honestly about as serious as I took my brand new 1992 GT and later another 1990 GT I bought used. Stock for Stock this 4.0 laid down the same exact ET on our 1/8th mile track as both of those cars have. Oh, and they have added 60 feet to the track since 2002 since it wasn't a full 1/8th. It is still a little shy but it is a country back woods track. It is only about 2 tenths off a full 1/8th now. Back then it was more like 4 tenths.

I may sneak down to the dyno soon. I will update you if you like. I will run the stock tune against a 93 firm shifting tune to see the differences. If the car lays down more than 190 to the wheels with a "stock tune" I would say it's coming from the CAI and exhaust but I don't expect much if any gains.

What CAI did you get, and where? I know the tuner is a must to wake this 4.0 up

This one is the exact model but mine is black. I could have gotten any color but I just like black. It's $82 but I think mine was like $106 with the shipping to my location.

Ebay Item 120423618759

I got mine from Ebay but I can't remember the seller.

Thanks for the information!

I'm running an eBay CAI as well, having likewise decided that paying $200+ for a piece of bent aluminum pipe is not for me. Mine's a k2motor clone of the AEM Brute Force intake, got it for $79 shipped and it's a mighty fine piece of bent pipe. Generic oiled cotton cone filter on the end, looks good, picked up a mpg or two, makes a cool faint whistly noise at WOT. What's not to love?

Patrick, it's good to see another skeptic/cheap bastard on the board ;)

a CAI without a tuner is worthless

guilty as charged. My only regret about the purchase is that I'm quite certain it wasn't American Made. Quality weld for the sensor though and the over all part seemed to be made well and fit great.

Just that the box looked very generic and I looked all over for who or what made it. Nothing but a pretty picture of the part on the box and a Part#. Same deal with a headlight set for my Fox recently. Generic box. I'd have paid $10, $15, maybe even $20 more to have it made here but not $150 more.

I can't say that it gave me any more than maybe 1 mpg at the most. The tuner may help that also but time will tell. I get between 23 and 24 now but I drive 16 miles of twisty two lane with hills. About 30 miles of 4 lane and I blend in traffic or drive ahead of the pack usually then about 5 or 6 of city streets plus lunch time traffic, each day. So I didn't see paying that much for it as it would take so long to get the investment covered.

I'm still not believing how much of a difference the Diablo made on such a mild car. The shifting performance alone saves in the old school valve body kits and not having to turn wrenches.

if the tips are rolled on the auto, then i suppose there is a possibility the sound is different... but I really doubt its noticeable. I've heard both ways on this one, people have told me they are very very different, others have told me they cant tell the difference.

Many people will tell you to stand next to an idling auto GT and an idling manual GT and listen to the difference, but the two are hooked to different transmissions, so I would think the loading and tuning would be slightly different.

I don't know what I would believe. All I know is I have the GT takeoffs from a manual, and they sound great.

Hmmmm, what I normally do in cases like this is consult a one of two friends that work a two different Ford Dealers. I get them to pull up the replacement part# and see if there is any difference in either.

My guess is the only difference is the section ahead of the mufflers to allow for the Transmission oil pan verses the stick shift.

There may be some resources online for this also. Or if you happen to know someone who owns both auto and 5 speed just crawl under and look. If the Part# is the same case closed. The sound difference would be due to tuning differences or any other mods ahead of the air pump (engine)

EDIT:

UPDATE: 2005-2009 Factory Mufflers Part #s. FI-7849-L FI-7849-R

These are what I have and I know of a 5 speed I'll check over the weekend to see what his are. Or if I'm bored at lunch I'll just hit a local lot I know with each, auto and 5 speed.

Manual GT muffler PN is FI-7849-R (or L for left side)
Automatic GT muffler is F1-7991-l

Well I guess I will go with whatever the best price is.
