Hi all,

I’m starting to plan out a new exhaust system for my 1967 Mustang and I wanted to get some feedback.  The engine is a fairly stock 427.  The car is a driver/cruiser.  The current system is a straight shot of 2.5” pipe from the headers to 16” turbo mufflers then a 2.25” stock
Below is my current plan and rational.
tailpipe with twin tip resonators.  There is no crossover pipe. 

2.5” mandrel bent pipe – should provide sufficient flow while providing more room for the install
H pipe – From what I’ve read, an H pipe will produce better torque for a street/cruising application opposed to an X pipe.
Dynomax Super Turbo with a 16”or 20” case (17629, 17749) – provides good flow without being annoyingly loud

I like the twin tip look so I may add 2.5” flowmaster tips https://www.flowmastermufflers.com/accessories-and-tips/15307-exhaust-tip-300-in-dual-angle-cut-polished-ss-fits-250-in-tubing-clamp-on/  or 2.5” Jones resonator tips.  https://www.jegs.com/i/Jones-Exhaust/523/JDR212/10002/-1  Jones is the only brand I could find with a 2.5” inlet. 

Originally, I was planning on going with the Magnaflow 15816 Kit https://www.magnaflow.com/products?partNumber=15816 with an X pipe .  I really like the stainless but from what I have been reading this setup will provide good peak power but it kicks in later in the RPM band so might not be as much fun for cruising.  I was also concerned that the Magnaflow Street Series mufflers would be too loud for my taste. 

I have no firsthand experience with any of these products so any insight would be appreciated.  Also, does anyone know if someone sells an application specific stainless exhaust kit minus the mufflers?

Hey guys,

I have a fiberglass hood on my Mustang that has a functional 1966 style hood scoop. I need to cut a half-moon shape out of an under-hood brace to make room for a taller air cleaner filter. Once the brace is notched the air cleaner will be able to sit up inside the hood scoop.

The cut will only be about 7” across and 3” wide. It will go about ½ way into the support. I don’t think it will undermine the integrity of the hood at all but if it does the support will be easy to brace. This is thin finished fiberglass. I’m cutting from the bottom up.

Any suggestions on what I should use to cut it?  I was thinking about trying a close quarters hacksaw or maybe a die grinder with a diamond blade

Hi All,

I'm thinking of adding a PCV to a '63 427 with a 6V intake.  I did some searching around and found good info but none of the photos in the posts were working.  My current set up is one breather on the driver side valve cover and the vent on the rear of the intake that I assume the road tube would have attached to.

My questions are:

1) Should I install the PCV at the valve cover or the vent that stands up from the rear of the intake?

2) If I do vent from the valve cover do should I plug the vent on the rear of the intake?

3) I only have one vacuum port on the intake (at the rear).  It is currently connected to the power brake booster.  Can I tee this port and run both the PCV and brake booster from it?

Thank you!
