    Mach 1 Mach Exhaust Improvements

    Hmmm, doesn't seem too loud. Can you say how much louder you think it is driving normally? How about at WOT? Is this the Borla system with the round straight through mufflers? What about the 2000 rpm drone, much different than stock? The stainless steel and rolled tips are the way...

    Laptop speakers ain't great, but sounds like an exhaust leak to me.

    Mach 1 Anybody go from an LS1 f-body to a Mach 1?

    I had a 94 Firebird Formula. Can't get a new Camaro or Firebird now, GTO is too plain looking. Tried the Mach1 and loved it right away. Unlike some of the posters above, I had no serious problems with my GM in 135,000 miles. A rodent of some kind built a nest on the engine while I was out of...

    Steeda Tri-axe Shifter problems shifting into gear

    The two things I'd look at would be: 1) Is the shifter stop for 3rd gear set to the correct gap (.010)? Some people accidentally set the gap in first gear insead of 3rd. I used a feeler gage to adjust my 2nd and 3rd gear stop gaps. 2) Is your clutch fully disengaging?

    Official Tremec 3650 Issues Thread

    I picked up my new Mach1 today. While doing everything else that goes with getting out the door, I had the saleman introduce me to the Service Manager. I had a nice conversation with him about the 3650 and the posting here on this forum. I said my new car (which I had just driven) did not have...

    dyno [B]PROOF[/B] on k&n filters....... part 2

    Just talked with a friend of mine who put a drop in K&N in his 2003 Cobra. Dyno run saw a 6 rwhp drop after installation. Then the shop re-programmed the chip for the new filter. Result, 11 rwhp increase over the stock filter. You must re-program for any induction change (his words, not mine).

    You have a 2004? If so, at what point did the problem first start and was the car still stock? Thanks.

    Official Tremec 3650 Issues Thread

    I have followed this thread on the transmission problems, but as I said earlier, it doesn't look like there is much in the way of 2004 owners posting problems. That's why I asked about the possibility of the new parts being standard issue now. I'm hoping anyway. I live in Legend Lake Estates...

    i have some dyno proof on k&n filters, ya know ya wanna see it!!!

    This industry standard for loss between the crank and drive wheels is 15%. That loss (or gain if you go the other way) will not be effected by which dyno you're on. The loss percentage is figured on the friction and 90 degree tork direction change (differential) of the car, regardless of what it...

    Official Tremec 3650 Issues Thread

    Transmission problems with 2004? I've read almost this whole thread (which took a while). I only saw one post from a 2004 owner. Is that a good sign? Do the new 2004 models have the newer cluster and syncros? I'm about to take delivery of an '04 Mach1, I'd like to think I won't be going down...
