im running:
megan LTH
invidia n1 catback
stock y-pipe
going to dyno sooner than later (still breaking in clutch)
will an aftermarket y-pipe make much of a difference than the stock one?

no, invest in an 07 hr y pipe, they are proven to gain a bit of power. Motordyne xyz is good too, but you wont find me paying 500 dollars for a y pipe (if they are still that much)
Also, i had the same exact setup, longtubes and invidia n1.. loved the sound but i hated the look of the two fart cans.. I just remember it was loud as crap.

no one is owned here. Maybe u should buy a HR y pipe and replace it with ur current then do before and after dynos and see if YOU have the same results. I did this at CIN Motorsports and LOST HP but gained 2tq. So def not owned son. Dont speak about stuff u dont have experience with

And to answer what is likely your next inquiry, the conditions were actually quite similar a year apart (on the same dyno as well - Dynojet at Keith's Pitstop in Gettysburg, PA).
June 29, 2008 - Popcharger & Ztube:
84.9 deg F - 29.66 in-Hg - 41% humidity - SAE 1.01
July 26, 2009 - Popcharger & Ztube & HR y-pipe:
86.2 deg F - 29.58 in-Hg - 33% humidity - SAE 1.01
I doubt you can get results that close on back to back runs on the same dyno day lol. Also, my best time bone stock was 14.05 @ 102.3mph on a 2.19 60ft. I ran with the intake a week after that and made no difference. But with the addition of the HR y-pipe (even on heavy winter wheels), I went 13.79 @ 103.5mph on an almost identical 2.15 60ft. Sure sounds like it works to me.

Maybe some are misinformed on my post. If I had to choose between aftermarket y and oem hr I'd choose aftermarket bc of Dyno results and collectors on test pipes. If the battle is between DE y pipe and hr them that's a no brainer. I was referring to hR and my AAM y pipe. And the day we Dyno slutted my car was on a Sunday and we were there all day trying out tons of combinations.

keep in mind that the outlet diameter Megan long tube headers and the HR y-pipe will not match up. The outlet on the Megan long tubes are 2.5" while the HR y-pipe is barely over 2". Even a cheap Megan or Nismo y-pipe will match the diameters of the LTH and Invidia. The Nismo/Megan y-pipe has a 2.5" Inlet and a 3" outlet which should mate perfectly to your Invidia if it's 3".
IMO, the HR y-pipe works great with the stock cats since it shares the same diameter but in this case, the OP is using long tube headers. Why attach a straw to a garden hose?

You right, the LTH do have a 2.25" outlet as confirmed by their website, but they claim their y-pipe has a 2.5" inlet.

I can't read anything you post without the guy in your avatar narrating it in some condescending manner
