Just got it and will install in a day or two. I ordered gaskets for the Cat hook ups (where Y pipe connected). Kit doesn't provide those and I didn't wanna use the old ones. I will dyno after I put it on..I have a baseline that I just did after my Osiris tune last week. It will really be nice to have info on how much HP/TQ this exhaust really does for an HR. Stay tuned..I'll post results of dyno here in a couple weeks or so.

 

I have this on my Z with Stillen headers and Stilleh HFC's. Its a pretty quiet catback IMO. Doesnt really start to really give a nice aggressive tone till about 4k RPMS...

Overall its a pretty low key exhaust which can be nice at times

 

i have this exhaust on my Z too, great quality, looks and sound for the price

 

Installed it today. Very straight forward..no glitches. Some have complained of tips being too far out (?)...hit mine with a mallet..they're perfectly positioned. Sound is VERY TAME (I have stock cats) but very deep and mellow. At WOT it ROARS but still deep. No rasp..no drone. It seems more responsive to throttle input....I'll get it re-dynoed soon and we'll see if adds power/torque.

 

Yea ikonda wish it was a little bit louder "/

 

Not me brutha .
I suppose test pipes or HFCs would definitely make this a lot louder...I don't plan on touching my stock cats.

 

it is pretty quiet. have had mine for about 5 months now and i like it. maybe once i throw on some test pipes i'll be satisfied.

as of now, having no drone and little to no noise while cruising on the freeway is awesome.

 

Yea i have headers and HFC's (both stillen) and its still on the quiet side. Then again i never heard the catback just by itself though...so i dont have much of a comparison lol...

 

Anyone notice better Gas Mi with this on? I seem to getting about 1 mi/Gal better.

 

Figure this would make cents eh?
