Agency Power and Berk Street exhaust muffler dimensions

AndyW · 03-31-2018, 09:50 PM

Anyone have pics or measurements of how much less they protrude down compared to stock? It's hard to tell from the sales pics. Silly question I know, but I am working to install a functional rear diffuser on a track car and would like it to be flat without hitting the muffler (Yes, I am aware of the race exhaust options but this car needs to remain streetable). Thx!

Related...I've seen that people modify the internals of stock mufflers to make it sound like the PE...anyone with muffler experience think I'll do any permanent harm if I just use a sledge to beat in the lower right portion of the muffler an inch or so? I know it will affect the sound, but it can't be that much, can it? Just seems like the cheapest solution right now as I have a lot of things on my "get for the track car" list and I'd really like to mount the diffuser flat. TIA!
