Mac longtubes - 2003-04 Mach 1 Registry Owners Club

Thinking about throwing some Mac longtubes on the Mach with a catted x-pipe. Is it worth the money and install?

I went with the Mac LT's & the matching H Pipe, for the money and install I think it's well worth it. I did the install myself and it took me about a full week only working on it 2 hours every day and having more time on the weekend and it wasn't too bad. I didn't drop the K member but it would've been easier if I did. If you have any questions just ask!

Do you still have to drop a header to get the trans out with the mac aswell?

Yes I believe you do, just have to loosen up the passenger side.

Did you notice a big performance increase? And is there anything else you need for the install that doesnt come with them?

I reused the stock manifold gaskets and used some of the factory studs and some of the supplied bolts that came with the long tubes. As for performance increase I haven't gotten a tune yet which would help me even more but I did feel more of a "pull" in the higher rpms. Deff worth the install, time, and money.

How much did the sound differ? i have been trying to figure out what lts to use & do you have a video after the install?

if you get on youtube, there a few videos of mach's with the mac LT's on there,

also the stock manifold gaskets are the best to use, when i did header install, didn't do LT's but they were the best gasket to use.
