Man, I usually don't get too excited about much of anything and I'm almost never surprised; but this morning I'm afraid I've gone off the deep end (well deep end for me anyway ).

I purchased a Magnaflow muffler last week (part number 14267) off of ebay as my next upgrade. My car is a 2000 SS with about 39K. I purchased it mainly becuase I liked the sound of the Magnaflow over stock - not becuase I expected any real performance gains from just the muffler.

I dyno'ed the car stock when I first got her and have mainly added appearance mods since. The only performance mods have been a lid, K&N, and the free trimming of the underside of the air box mod. Honestly, I never noticed any seat-of-the-pants difference with any of the above performance upgrades. In fact, the only difference in performance I've noticed, since she was dyno'ed, was a change in the clutch because the original one gave up the ghost. I guess it had always slipped from day one because once the new one was in, I was much quicker out of the hole and could get rubber much easier than ever before.

All of that to say this: After having the Magnaflow muffler installed this morning I think I can feel a definite difference in performance. As the subject suggests, someone please wake me from this dream - surely there are not enough new ponies for me to feel the difference, right? Remember, I am the ultimate skeptic, but I'm telling you I feel a difference.

I am goinig to take the G-Tech out of the box later today and see what it says, but sadly I never got a HP baseline to compare it with using the G-Tech because I had the dyno results already. I'll post more after I do that, but I just wanted to say how elated I am at the seemingly cheap and easy boost in seat of the pants enjoyment I have stumbled upon in my quest for serious performance sound.

I guess all that really matters is that I'm happy with it and that I perceive there to be some gain as I don't ever race and certainly don't do the drag strip thing.

Cheers to the SS

 

congrats on your new found power, i've thought about going with magnaflows.

 

Magnaflows always have been a good power-making muffler. Congratulations!

 

I yanked the Magnaflow system off my car at the track one night and ran no faster without it. I've seen another post with a guy making 511 rwhp with a Magnaflow system and 519 without. So even at his level, it is only costing 8rwhp.

 

maybe that newfound power is the deception your ears are giving you....

 

My brother's ws6 never got a baseline dyno but with an slp lid, k&n filter, and magnaflow catback he made 328 rwhp and 343 rwtq
