Slp
 

Well, I just added an SLP Catted X to my SLP Cat Back....HOLY CRAP! I now have a NASCAR parked in my garage.

Before I put on my Magnapak, I was debating between SLP loudmouth vs. Paks. Then I heard an SS around my house with it on, and quickly decided for the Paks since this is my daily driver. I think SLP sounds nasty good, but would give me a headache driving it everyday. :D

my buddy with a 03GT has the SLP longtubes and off road x with 2 chamber flows
and I love the sound of it

my new setup is mac long tube headers with BBK h pipe and dumped magnaflow muffs

Explicitone did you lose any TQ with dumps? Most Mustangs lose TQ with off-road midpipes and with dumps. Just wondering if you lost any.

if I did it was not much but I will say the car lost about 30lbs without the tailpipes

plus I had 4.10s when I did the setup

and no0w I added the longtubes so the tq is there:D
