I currently have the stillen cat-back and it's the only cat-back i've ever had. I don't really like the sound it gives the car though. I bought it used and it feels very worn out and "droney." It makes the car feel a little sluggish IMO and it also has an annoying raspy sound.

I want to get the Greddy SP2. Has anyone gone from Stillen to Greddy? Will a brand new Greddy give me anything over my current Stillen or will it just be cosmetic/sound improvement? The thing I hate a lot about the stillen is also the really loud drone it creates between like 2.5k and 3.5k rpm (i think) when you're just cruising and you give it lots of gas before the auto tranny wants to downshift.

I know the Greddy is a better exhaust but I just don't really know specifically why. I tried to search but it keeps giving me error messages. If anyone can help me out that would be awesome. Thanks!

 

I have never switched between the two, but I have a Greddy SP and it sounds really good. The Stillen exhaust sounds horrible(IMHO)...any exhaust you get will sound better than the Stillen set up.

 

Never had the stillen but i love the way my SP2 sounds like. Low sound levels on a gloomy day and loud on those days the car is feeling the need for speed. Other people probably have a diff opinion.

 

besides sound, does the greddy make the car feel any different? i feel like the stillen makes the car kinda bog down a little and drone a lot. any performance benefits?

 

No Stillen experience, but I have the SP2 and it rocks! Low rumble, no rasp, mellow most the time unless you get on it, then BBBWWWWAAAHHHHHH!!!

 

hahaha. i know it sounds good but someone has had to gone from the stillen exhaust to the greddy!

 

Bbbbaaaaawwwwaaaahhhhhhhhhhh!

 

hmm....i liked the sound of my stillen, altho i only hadd the axleback.
