If you get the magna packs its gonna sound realy good, and realy realy loud... same way with the slp LM 1's... If you get the LMII's there alot quieter but still sound good. performance gains are the same. You are pretty much buying the name... no complaints for SLP here... I like the tips.

Magnapacks sound better IMO

performance would be the same, sound is preference i love slp sound. i notice in your sig you already have and lm1 catback, if your thinking of going to the lm2's i have a set of resonators in the parts section for sale. there supposed to be deeper

SLP sounds like *** to me....i would go for the Magnapacks

Deff. SLP, It's modular, so you can get the cat back and then choose between the three sounds, LM1= LOUD, little raspy at high RPM, but super deep and nice at low RPM,,,, LM2 quieter than the LM1's and a bit deeper, the most similar to magna packs, then they have the power flow mufflers in case you ever need to be even quieter while stimm maintaining good performance,,,, Plus the entire system is stainless, the fit and finish is flawless and the double walled tips are sexy!!

hot wheels

SLP FTW!!

packs all the way! i just got them on my 99 gt and i was debating between the lm1/2 or the packs and i went with the packs and the magnaflow x pipe and i absolutly love the way it sounds! i would go with the packs.
