Opinions? Next Mod: Catless front pipe or lightweight aluminum driveshaft
 

See signature for current mods. This is my daily driver including frequent highway trips, so goal is stay reliable. That means stay NA, no footprint tuning only, sticking with 93 octane and giving weight reduction high priority for every mod (for example, I chose 17" x 8" RPF1s to drop 5lbs per corner instead of go larger).

I've been debating will be either a driveshaft shop lightweight aluminum driveshaft or a catless front pipe/ over pipe combo.

Since I've got a Borla cat back I'm considering the Borla cat delete front pipe / over pipe combo. (I have a Unichip to take advantage of the exhaust mods).

So... Driveshaft or catless front pipe... Which would you chose and why?

Long term plans include Speedfactory headers, lightweight flywheel and 4.56 final drive.

While I've become more or less immune to the noise of this vehicle (it's just plain noisy even without mods), I'd like to know if anyone here has the Borla catless front pipe? It's not resonated, does it rasp or drone? The Borla catback growls nicely at all revs and has almost zero drone, I'm wondering how it will interact with the catless front pipe.

You will lose more weight from driveshaft than HFC. 12 lbs vs. 5.
