Magnaflow and XLerator are made by the same company. It is the same muffler. The XLerator is slightly less in quality while the prices are comparable. This info comes from my local custom muffler shop. He'll order whatever you want and build the exhaust one-off. I have opted for a s/s Magnaflow 14" resonator and 14" straight-through muffler for my 240Z. I'm building my system out of mandrel bent 2.5" 304L throughout. The header is a old school s/s JanSpeed 6-2-1 2" collector flared to 2.5". All of the piping and clamps were purchased at www.verociousmotorsports.com. I have close to $900 in this when completed! Crap, that's lots of $$$. It should last 10 times longer than a mild steel system.

That is good info to know! $900 on an exhaust! That's pretty much overkill for me.

I ended up ordering a Delta Force Race muffler and a Dynomax race bullet muffler to place in the trans tunnel. I will then get some custom 2 1/2" pipes bent for it. I'll let you know how it turns out.

Thanks to all that contributed their opinions.

Sounds crazy and it is. I don't drive my toys too often and rust is a killer on a parked car's exhaust. We are talking about a complete stainless system though. Besides the $400 header the other cost were $275 for tubing, coupling, expander and O2 bung. Another $150 for the Magnaflow pieces plus shipping charges. At least, I'm saving money by cutting and welding myself. In the end it is an exhaust that is easily removed for services and a life expectancy over tens times that of mild steel! It almost sounds like a deal when you look at it from that angle.

I am running 2 1/2" from the stock manifold to a 2 1/2" magnaflow muffler. sounds awesome at idle but too loud everywhere else. thinking of adding a second muffler to quiet this down. not a ricey sound either. 1975 280Z
