Exactly! I only had mines on for 1 day before they came off and the slp's went back on.

I have always wanted MAC's and finally got them. I took Magnapacks off for the Mac's. I LOVE MY MAC's. My 4 yr old son loves hearing the car also. Drone decreased at cruising speed with 4:10's.

Two follow up questions...

To the MAC users - how many miles was their break-in period (if you managed to keep them installed long enough) ?

To the SLP users - most mention Loudmouths; any SLP Power-Flo(s) out there ? Any thoughts/opinions on the Power-Flo(s) ?


2008 GT ~ candyass red ~ JLT intake ~ SuttonHP tune ~ SLP PwrFlws ~ FRPP 3.73s...more to come / stay tuned.

After the break in period mine got louder which thank God because I thought I spent too much money having them sound no better to me than my magnapacks. I would say it only took about a week. Although I only ran them a week before taking them off and having them ceramic coated black since polished stainless looked kinda goofy on my car

Good choice on getting the Boom Tubes! I love mine. If you plan on getting long tube headers just know you will have to then push your car a few blocks away before you start it.
