prodrive = bosal?

I'm currently currently a HKS dp with Bosal single tip 3 catback. The car is kinda loud for me.. so i purchase a prodrive axleback.


Will the prodrive bolt onto the bosal rear center pipe?

If it goes bolt up, will the car loss power because it's going from a 3 inch to a 2.5 axleback?

Not really, since on a moderate leveled car, the exhaust fums actually cools (the gas becomes less dense) as it exit towards the mid/end portion of the exhaust, requiring less volume in the pipping.

Depends on the car, but in some case, if you have a full 3"+ pipping all the way, fairly on a stock car, you may lose some velocity in the flow at the end causin minor tulerence.

But, if you have pushing some massive HP. then yeah, a 3"+ is plus =]

It'll bolt on but it probably wont tapper smoothly from 3" to 2.5"..... unlike the TXS, where the end on their midpipe actually tappers into a 2.5" before the axleback
