Mac Long tubes

[Daniel50]

Just ordered a set of mac longtubes and the matching shorty off road H pipe. Had a few questions

1. What else do i need? MIL Eliminators? O2 Extensions?

2. What kind of power gains on a basically bine stock gt?

3. What Cat-back sounds the best with this in your opionion?

mil eliminators are not necessary on our cars. you will need o2 extenders. as far as a catback, i have a flowmaster american thunder with mac 1-5/8 longtubes and a prochamber and i love the sound.

I hope you bought the headers with ceramic coating. The chrome ones discolor around primaries. The HTC coating or whatever MAC calls it will eventually chip then rust. The extra expense of ceramic is money well spent.

agreed.....ceramic is the way to go. the finish stays looking good and you also get the bonus of the ceramic coating dispersing the exhaust heat better.
