I had the x pipe running w/stock mufflers and actually liked the sound i got,but once added the flowmaster 40's, it really woke it up! Just too much "noise" in my opinion. If I were still in my 20's, i may have loved it...
I did some research on BBK's website and they state: "We have noticed over the years that Flowmaster muffler systems when teamed up with our off road X-pipes, can work together to create an exhaust note that not every enthusiast will appreciate...BBK recommends a muffler system that is a direct-flow type, similar to a Magnaflow or perhaps a Dynomax, should the Flowmaster system not work for you.
I like the flowmasters - don't mind the drone too much. I had the flowmasters and an h pipe on my 89 and 90 GTs and loved the sound. I like the growly,throaty sound, but with the x pipe, it was in my opinion chaotic, metal banging around at 2k-3k rpms and just way to much for me.
I just want to see if anyone can advise on whether i would experience the same or similar with an h pipe combination.
Thanks!
