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"
