Hi guys!

I'm looking for some local guidance on tuning my 2015 GTS. Firstly, my car is mostly street driven with the occasional rally and track day. I'm keen to unlock some of the mid range torque that is available with a tune and exhaust mods. I am not at all interested in a HP figure, I'd just like to fill out the torque curve in the mid range to improve driveability. Unfortunately I don't have easy access to E85, so ethanol tunes or flex fuel is out.

Also, I want to keep my car sounding as stock as possible. I know I'm not impressing anyone when I make lots of noise, and so prefer the stealth approach to my hooning. I'm not interested in fitting a catback at all unless it is necessary to keep the noise down, or if the catless header on it's own sounds bad with the stock exhaust.

So far I'm leaning towards an OFT and catless header of some type, but don't know what to expect on the noise front with any combination. I don't know anyone with an 86 so it's hard to find what I like.

Can the collective wisdom offer some advise on whether or not I'm on the right track for performance mods, and some specific parts to look at. I have no budget in mind. I know headers can be had for between $500 and $2k, and an oft for about $750 delivered. I'm cool with products in that range.

TLDR:

Can anyone offer advice on a tune / exhaust combination that will flatten out the torque curve while staying stealthy.
