aight so i went up to Larry Greene (does the best exhaust work around richmond) and he is asking for $425 parts, labor, everything for the flows 40 and it would take em 2 hours.
Is it a good price?..........kind of high but I would call around
Does everything sound legit? is that mandrel bent pipes
Questions about the 40s:
How much increase in HP? may 2 HP gain at best
How much Torque - gain/loss? with 2.25 pipes neither with 2.5 pipes a loss
Will it effect my gas mileage? NO
Will it shake the car? NO but it will be noisy at highway speeds
Street Legal? Yes
With or W/o a catalytic converter? With converters
Really with a near stock motor you wont gain much power and no torque gains, just really sound better. You can consider Dual exhaust as a necessary step in the modding world. As you get more mods especially P&P heads, intakes, SC or Nitrous you will need the extra flow.
