I can try to get a dyno run in sometime in the next couple of weeks but I don't have a stock baseline and I have other mods.

Post #3 has dynos of their full system. A catback will be slightly less.

I'm aware of these results although I appreciate the help. My point is that we don't know how much less HP the catback would add. I would like to put a number on it

Same here, Dec 3rd delivery! Will give me some time to organize the garage during the weekend and get it ready (making wheel/tire set and car part storage shelving to give more space)...

Just finished installing and doing a hard run to break in the exhaust and get it hot... honestly thought the exhaust would be louder than it is. Probably the quietest exhaust I've had on any vehicle. Nice start up rumble and smooth sound, and definitely feels like it's more eager to run through the RPMs - unquestionably better than stock. Sounds nice when on elevated roadways with concrete sides and getting on it around 6k and I like the little 'blap' (not a backfire or stutter, but a nice, short, not loud 'blap') it makes when getting off the throttle or even shifting...

Looking forward to spending more time with it...

Oh, wait.

Mine came in yesterday, too. Hopefully will find time to install it later this week.

Genomaxter · 12-04-2012, 08:36 AM

Installed mine last night in 1.5hrs total. It sounds deep. Like guilty deep. Lol. Looks sexy as he'll too. Weld are very neat and exhaust fit perfectly.

Genomaxter · 12-06-2012, 06:03 PM

Well, after a few days of driving more than 220 miles, it is still droning like it wants to kill me. If you get this cat-back, you better have your stock Helmholtz or maybe even a Nameless one. I have a nameless with a high flow cat, but I ordered before the Helmholtz were an option and now im paying for it. And so far SRT doesnt think I can put their larger resonator on. If I cant fix this, im going to have to butcher something or just take it off. I cant go back to my stock front pipe since my bolts were cross threaded from the factory and I had to cut them off. Such a shame cause the exhaust itself is very nice and I love the sound minus the massive drone.

Flatline, here are pics.

Genomaxter, I'm a little confused as to what system you are running. Are you missing the Helmholz because you have a non-stock header/mid-pipe connected to the SRT cat-back? I have the SRT cat-back which retains all the cats and the Helmholz and mine does not drone. Can you clarify please? Thanks.

Everything before the catback and after the header is a nameless exhaust.

vubaru · 12-08-2012, 12:40 AM

My SRT catback did drone a lot before I installed the Nameless Downpipe/Overpipe with the Helmholtz resonator.

I'm having a hard time aligning the exhaust with the Kartboy hangers. It's almost as if my tips are a little uneven. Might have to get the "longs" or go back to stock.

Genomaxter · 12-08-2012, 03:10 AM

I dont have a Helmholtz on my nameless, but I am currently working with Nameless to make one for my issue specifically. Which I find to be fantastic customer service! I was just playing with a frequency analyzer and my high db readings were all 250hz and below frequencies with 65hz being the highest at -20db.
