Yeah... Magnaflow is already straight-through -- good enough for my 530rwhp 408ci LSx motor.

 

Magnaflow is the catback I'm going with this spring. I've got longtubes, ory and straights right now and it's way too loud with my 3200 stall. Even pulling away from a stop sign sounds like I'm standing on the gas pedal. I just need the magnaflow to calm it down slightly to avoid getting ticket after ticket.

 

I'm running LTs, with the new TSP Ypipe (nice merge), and GMMG catback. It sounds good. Still have some rasp, but I've never heard a ypipe setup that doesn't. Best sounding is true duals, but they are loud on a totally different scale. More Interior noise then anything being dumped...

 

I have Pacestter LTs and ORY with custom 3 inch back to a single Magnaflow. It is decently quite at idle but screams at WOT, with a little rasp from 2000 to 2700.
