O/R H - Pipe 91 GT

I have an o/r h pipe im thinking about putting on my 91 gt. it came with the car when i bought it a couple days ago and i was wondering exactly how much louder it would be, i already have 2 1/2 flows on the car. and new headers.

If you have the factory 4 cat H then it will make a difference in both sound and performance
