Three questions I need your help with. I have to decide this weekend ... car's already in the shop waiting.

1. How much more power did you make going from MAC's to long tubes ?

2. Are your LT's 1 3/4" or 1 7/8" primaries?

3. On a scale of 1-5 ... how would you rate your level of satisfaction by stepping up to LT's?


Right now I have well ported MAC 3/4 mid-length headers with 1 5/8" primaries and a MAC ORY with a Flowmaster junction.

I'm thinking Kooks headers with Kooks ORY with 1 7/8" primaries will push my power band up higher where I need it most. With my A4 and 3600 stall, there's too much unusable power down low.

Kooks is worth at least 10 rwhp over the MAC's.

I just switched from Macs to Kooks LTs...no new numbers yet though.

I'm hoping to see anywhere from 5-10 more hp from the LTs as well as more torque.

I went with the 1 3/4" X 3" SS race headers and 3" SS ORY...very impressed with the Kooks quality and fitment.

It seems that there are still people who can't wrap their brains around header primary tube theory. A LT header will not dyno with higher peak numbers than a set of MAC midlength headers. The smaller y-pipe might hold back numbers slightly, but just the header tube difference in length is NOT going to affect peak rwhp numbers.

There have been numerous people swap and pickup ZERO gains in peak rwhp.

Since when does MAC make a 1 5/8" header?

You want your power band pushed up higher? Go with SHORTER header tubes. They'll up the rpm range of the motor. A longer header tube will INCREASE LOW END performance- not top end pull.

Not another LT vs shorty thread again...

looks that way, besides macs are a mid length header not a shorty.

... you get the point, I'm sure. Inside diameter is 1 5/8" ... so that's what I call 'em.



Looks like I'm not seeing the worth of paying $1,500 to change up ... except for the fact I'd have nice stainless Kooks 1 7/8 headers. Guess I'll hold off until the nitrous kit goes on this summer and just do it all at once because I'll then need them.

The sound of LT's are worth it alone IMO.

I went from macs with a cutout to pacesetters with TDs with 1chambers and it was a waste of money ran no better..it did however sound better

No dude, I have MACs on my car currently and I'm trying to tell you they are 1 3/4" tubes. They really are not that bad.

Yeah, I've loved my MACS a lot and for a very long time. The sound of my exhaust is exactly what I strived for through 5 different exhaust changes from Borla adjustable to cutouts to true Duals to what I currently have now. Previously, I had Random tech bullet cats welded in my old MAC Y to eliminate the rasp ... TWO DIFFERENT TIMES!

It's pretty loud and I have no cats ... ZERO rasp whatsoever ... just MAC's, MAC ORY with Flowmaster junction, and Magnaflow single-chamber muffler Catback. Frequently, I get comments form the Cobra folks becuase they can't believe how good it sounds.

I was just thinking of more power, but, doesn't appear up where I need it ... the 90/90/90 setup put me about where I need to be ... was thinking better air intake would further complete that goal. Not the tube length, necessarily.

Well, the debate will ALWAYS go on, I guess. Just started this thread hoping to hear from somebody who has stepped up from MAC's to the 1 7/8 LT world. Haven't heard anything that's very convincing .... seen some dynographs, but, the weather/temps and days were different and the differences weren't enough to really say the comparisons were accurate.

This all being said, I still love my MAC's, as cheap as they are. After 4 years on the car, I would say they are in far better shape than any non-stainless headers I've ever seen which are that old.

Thanks for the for responding and I guess I'll be keeping the MAC's ... at least until summer when the nitrous goes on.

I think for the money could be better spent on something else possibly.

What about if the car is lowered? Then is it better just to compromise by getting some mids? I'm thinking about getting some headers, and other than wanting the car to have emissions in tact in case I ever sell it . I live in Ohio where the majority of the state currently has no emissions testing . I have an electric cutout as well if that affects anything.

the MACS dont affect ground clearance
