Thanks alot for your time
2.5 mandrel bent won't be that horrible... but OTOH, it won't give you much in terms of HP by itself.
If anything, I'd be more concerned about quieting the resonances that will be inherent to larger piping.
Back when I was considering turbocharging my DC4, I had a 2.5" mandrel cat-back on the car. It was far too buzzy and resonant to be suitable for a daily driver while the car was naturally aspirated. And that was with a large muffler and long perforated-core resonator.
Frankly, if you only have $300 to play with, I'd keep the car stock until power-adders made an oversized exhaust advantageous.

Do you have an idea of what your long-term plans are?
What's your budget, how reliable do you need the car to be ... and how fast do you want to want to go?
