I just installed dual "stainless"high flow cats and exhaust. WOW! What a BEAST! I can't belive the addition of power. I didn't think it would be that significant. The sound is absolutly awesome! Imagine, I was sold on another system until I started researching. There were two guys in the shop with Mustangs going to install cat backs from another manufacturer until we fired up my truck. Real sound! Not an anoying wapping sound. Afterwards they both drove off happy. I had three guys stop me on the way home and inquire about the sweet sound. Lifetime Warranty to boot! Hopefully this will help a few of you guys decide. The first day giggles are back once again!

 

What Magnaflow mufflers did you use?

 

Magnaflow PART#14568 5x11x22 Dual IN/Dual OUT Oval "STAINLESS" w/High- flow cats. Re-used the factory tips but fit them level with the bottom of the body skirts and proud a 1/2". The craftsmanship of the shop I used is phenominal. I thought that two independent singles was the way to go, but the dual sycronises exhaust better in the reports.

 

i got the 12468 on my 01 L sounds awesome.

(E3LilE8Harv29)--cool name
nice to see another L owner thats dale jr fan.

 

is it low end or top or both?

 

I am noticing significant power gains throughout now that I have had a couple of play days on both street and highway!Getting louder&louder. Nascar sounding for sure on the highway but mellow don't arrest me rumble at idle.
