Very good. Had it on my car and my friend had it on his car. Don't sound as good as with an axleback, but they do sound very good.
Sounds good, but not as deep as most axlebacks. off road H + regular Magnaflow axle backs or GTA's sounds really good, but not overly loud.
i agree with all that has been said. i have O/R H with flows, and my brother in law has O/R H with stock mufflers. they sound similar. save your money on axlebacks and see if you like the stock & O/R H combo first!
I have O/R H with GTA mufflers. here is an old vid of when i first got it installed. The GTAs have broken in well with the O/R h and sound much better now. I'll get some vids tomorrow for you and post it here. Stock w/ GTAs VS Pypes O/R H w/ GTAs YouTube - 2007 Mustang GT Mid-Pipe/Axel Back Combo
Pypes O/R H and factory mufflers. It's relatively quiet while cruising and at lower RPM, but when you get on it, it wakes up and there is absolutely no drone. Outside: Inside:
hey kool, I love your front end, what have you done to it. I notice a bullit grille but it looks different. do you have the SHR lower grille inserts too?
Just did this mod last month on my 08, sounds excellent, just like the above vid, no drone and nice thoaty roar. Go for it, only hassle is the check engine light, but not if you have tune.
It is the Bullitt grill that I painted the front silver and added the tribar running pony fender emblem. I do have the SHR lower grill inserts as well.
I have the stock exhaust and love it. I ran Pypes Violators for several months and started to get ringing in my ears on a daily basis. It's been more than a month since I went back to stock and the ringing stopped as soon as I stopped using the Violators.
