►►►Custom 2" Catback - What next? Please help

[NJP440]

I had a 2&1/2" custom stainless catback made from the second back straight to the muffler deleted the resonator and it came out pretty decent. I also have installed the Whiteline rear swaybar, tein coilovers, UR rear upper brace, and megan racing c pillar bar (useless I know It's just for looks lol)
I'm definitely impressed with how my car performs and I'm excited to throw on the 1zz throttle body I've had sitting in my closet for a year and a half lol

Nice sound. I had to change the OEM resonator to this one of 24".
The sound improved a lot and I did not lose the power I had gained.

The inner diameter is 2", this is custom made.
A friend recommended a vibrant, and I was about to install a Magnaflow Glasspack.

I was referred to go magnaflow I'm trying to keep an even 2.5" the full way back but I definitely need something a little quieter before I get pulled over

If you're keeping your engine NA then don't go larger than 2.25".

I decided to take the advice of a reputable and very good exhaust shop against the advice of some of the experienced YW members and I lost noticable torque. Had the shop re make a 2.25" and most of the torque came back and still has the increased top end.

That was with all the flow mods -dc header, MI intake manifold, intake, 1zz TB.

Ya mines getting boosties 😈 GT2860RS with custom tubular manifold and Haltech standalone. I'll post more on that as I progress. As for now I just have a closet full of parts just waiting on the money to purchase the rest of necessary parts.
Only reason I opted for 2.5"
