I have a stock 2000 A4 and plan on get a good cam 224 114 or something similar along w/doing all the bolt ons incl. LT headers. Now a friend is not going to use MACs w/orp that he ordered and is willing to sell them for a good price. Now the question is, what doors will I be closing if I go w/mid lengths compared w/LTs

 

the difference between the 2 are a few inches. I have Macs on my car.. i love them

 

I think MACs are less likely to have clearance issues.. but I still want LTs on my car.

 

flp longtubes......they dont have that many clearance issues....well at least they dont hang as low as slp....i got 23rwhp from them and they look great.....

 

I talked to a guy last week who has helped install both SLP's long tube and MAC. He said the MAC's where alot easier to install but you may sacrafice a few hp with them. If your looking for every last pony, don't mind doing something that may be a little harder, or may be a little more expensive then long tube are the way to go. I have heard several people that where very happy with the MAC setup and I am currently thinking of them for mine. If you don't want them and hes making a good deal, IM me and maybe you can make a few bucks off being the middle man.

 

I am very satisfied with my MACs, especially for the price. Make sure you clean up the welds, do the collector mod and DO NOT use MAC's cats. You will only lose a few HP compared to the LTs and the install is pretty easy.

 

Thanks for the replies. What do you mean by "the collector mod"?

 

www.hpaparts.com

has a good deal on macs right now

 

If your on a budget go with the macs, if your looking to squeeze out every last horsepower than go with hookers or a similar lt. You'll probably only pick up 5hp if that with lts vs macs.

 

The "collector mod" is getting rid of the ball-flange and welding in a Flowmaster collector. Not a must do cahange, but every pony counts. I reused my stock manifold bolts, but many people use the Stage 8 locking bolts. Good luck and let me know if you need any install tips. Ben

 

I installed MACs yesterday on my car with a buddy, and it took us 7 hours. It went pretty smooth, but the passenger side header is a PITA to get in. We had to remove the STB, coil packs(pass side), and remove the tranny mount bolts so we could pry the tranny/engine over about a 1/2". And with a ton of hammering on the header with a rubber mallet, we finally got the header in.

After that, everything else was pretty easy. I love the sound and all, but we're in a blizzard at the moment, so the car's still living in the garage

BTW, I also have dual cutouts for that true duals thing when I feel like it
