Anyways, I also installed an Invidia Q300. The car sounds great with my current setup.
ACE 421 B350, Invidia HFC FP and Invidia Q300 CBE

But, I am very tempted to put the ACE FP back on and see what sounds i get. I prefer quieter exhausts, or at least ones that are not obnoxious in low to mid rpm range. But, dare i say that the car could use some more volume.

As i said my main concern right now is fixing my coilovers, but I will come back and post some video/audio clips to show the ACE and Q300 off, with the HFC FP and the ACE catless FP. I think with this CBE the Ace front pipe may work fine. I will report back when i have more.

I'm awaiting video of the new setup... please.

I remember those videos. I had already ordered the front pipe by then.

I meant to post this sooner but here is my dyno results. Please note this is on the Dyno Dynamics "Heartbreaker" dyno and this is equivalent to ~200whp on a dynojet from what I've read.


Mods:
Grimmspeed intake
ACE Type B 350 headers with ceramic coating
ACE front pipe (has been replaced with JDL Ultra Quiet FP)
OFT
Koni Adjustable shocks/struts with Eibach Pro springs
Enkei Kojin 17x8 wheels wrapped with Michelin Pilot Super Sport 245/40R17 tires

Reamer: OFT? What tune do you use? And do you have baseline on this header with stock header?

It is a dyno tune by my local shop. Unfortunately I did not grab a base run on the stock car. The first run after installing the parts on the Vishnu stage 1 tune was around 164-167whp.

I hope they didn't simply adjust the fuel and timing on stg1

I'm mostly ignorant when it comes to tuning and I know they changed those values, but I'm not sure what else there is to change. The AFR's on the other printout I was given look good, but again, I don't know much about those ideal numbers. Regardless, it made at least 10whp more than stg 1 once they were finished and I don't think they just made it run rich to get that extra bit. It would be interesting to have another tuner check it out though. I can upload the sheet that has the AFR graph if you would like, and I can do some more logging on my OFT. If I go that far I would just start my own thread instead of piggybacking off of this one.

Be sure to check what mode they have it in. Dyno Dynamics has a "shootout" mode option that emulates something like a dynojet and will read much higher. In that mode mine read 201whp.

Edelbrock, ACE 350, ACE FP, Tomei 60s ?

Should I buy some bose headphones?

Get ear plugs to go inside the headphones.

Has anyone purchased the 4-1 and gone with a different OP and FP setup?

I'm looking at the ACE 4-1 (1 Piece)
with the nameless OP/FP HFC and resonator (to tame the 60s).

Wonder what the performance differences between a dual resonated Hks or fujisubo resonated front pipe compared to a Tomei front pipe when paired w an ace header
