Here is a comparison video between SLP and MACs. When I took the video for the MACs I couldn't really get on it in the parking lot as a a car was entering.

They both sound really good, probably the slp more..

 

I know you can't tell from the video, but even with catted x and resonators, the MAC set-up has that classic MAC sound. The only difference is that it's not as hollow sounding.

 

I like the more hollow sound the resonator gives, kinda like a mid muffler.

 

The MAC set up is slightly more sounding than the SLP, but it's not as hollow as the typical MAC set-up

 

Never been a big fan of the SLP systems, only when you have the stock manifolds and midpipe is when it sounds good. Once you upgrade to headers and an off-road or high-flow midpipe they just get a little to loud....MACs sound great though, the remind of the flows everytime I hear them.

 

That's what I tell people about the SLPs. The SLP set-up was a little too loud without resonators. It sounds much better since I put on the resonators. But I think I like the deeper tone of the MAC set-up.

 

But the slp LM tips sure do look great!

 

They do. In a few weeks or so I will put the SLPs back on.
