Got my megan resonated test pipes installed and i love them, it sounds great and really peps up the engine a bit. I am keeping the stock rear mufflet setup but am thinking about getting a Intesepower Y Pipe. Will there be a noticible differance in sound or power? Looking to keep the stock tone but louder which is what the test pipes did, but a lil louder would be nice Thanks for your help

I may eventually get headers.

 

Yes, it will change sound and power a little more.
If you like the test pipe sound, you will like the slightly more agressive tone the ypipe will make.

 

do we have to worry about the quality of the resonated test pipes? (welds and resonator)?
