Getting ready to replace resonator with Magnaflow Tru-X Muffler - ZR-1 Net Registry Forums

HAWAIIZR-1 · 07-12-2015

I decided against buying any of the exhaust systems out there for our cars. I am replacing the stock resonator on my 95 with Magnaflow #12468, 2 1/2" ID in/out. Decided against just an X pipe not being able to find the exact size I wanted and also not wanting to take a chance with the dreaded drone. The size appears perfect fit based on measurements and the center to center is same like stock at 4". I like the thought of an x-pipe design within an open style muffler.

Here is a little peak inside through the other end; difficult to photograph this angle.

Mufflers are Dynomax VT with single 2 1/2" in/out. According to Dynomax you need an H or X in front of these mufflers to ensure no flapping of valve. Supposedly not good for cammed or big CI motors from what I read. One member has good success with the Dynomax VT in 3" on his 415 so I thought I would try them. The mufflers and tips should arrive tomorrow then off to the muffler shop. The tips are Black Series dual 3 1/2" double walled from Red Tail Performance. If I don't like this setup I will probably end up with Corsa's w/black tips. More to follow on this project........
