Here it goes..... Mild 350, Stock Pre- Smog Intake with "Tuned" Q-Jet , Soon as possible an Electronic Ignition System - Any suggestions ? A Comp Cams XE 268 H Cam Kit with some mild porting, I'll also be upgrading to a T/A Dual Plane Intake . Will be running Original Dual Exhaust for the time being , but will upgrade to headers . But for the mean time what do these 350's like ? 2 1/4" or 2 1/2" systems ? X-Pipe ? Was considering Summit Welded or Dyno Max Super Turbo's for the mufflers . This is going to just be a nice cruiser with a "little pull" . I also want to do some work on the Turbo 350 . Thanks for the input , Steve
exhaust sizes I've got a 2 1/2" system (not mandrel bent) with an X-pipe and Cherry Bomb Turbo mufflers (short case) on my '69 350 and I LOVE IT!! I added the X-pipe before my last trip to the track, had an H-pipe in it before, and I picked up .3 and 1.5mph. It has a nice rumble at idle, yet on the highway I can hear the tires over the exhuast, very quiet.
Pipes for 350 Thanks Ken. That's just what I was looking for . I didn't want overkill and loss on performance . Plus I like hearing the engine etc. Steve
I agree w/ Ken that the 2.5 inch is the way to go. I have 2.5 mandrel bent with an X pipe (which also increased my stats at the track- vs. the H pipe) and I have 2 chamber Flowmasters on my '65 300. The sound is fantastic! Matt
65 300; but isn't that a Mopar??????????????? Hey Matt ! Whats' Up ? Boy , You're brave .. Did you Epost me one time asking if I was the same "Desertrat" @ Moparnuts ?

Question I currently have a 2 1/2" straight back system (Hooker super-comp) headers, no X-Pipe, with a set of flowmaster 40 series mufflers. Would I notice a performance increase by putting in an X-pipe? --Sorry but I know next to nothing about this. James
James, One thing you should notice is less noise at highway cruising speeds. I've heard a lot of people with Flowmasters systems complain of bad resonance (sp?) at certain rpms and even some vibration problems. Adding an X-pipe has cured many of those problems. I'd say if you don't have any sort of crossover now, adding an x-pipe is definately going to help you performance-wise.
James, Ken is right. The 'X' pipe has proven to solve the 'drone' or vibration many people have experienced inside the car at idle and cruising. This appears to be the case with the Flowmaster systems and even some Dynomax systems. The lack of 'drone' itself with the 'X' proves it's gain. Let me put it this way - the 'H' pipe clearly is NOT a direct, uninterrupted flow for the exhaust. The 'H' creates turbulence at the point of crossover, thus the reverberation/drone. As well, this turbulence creates a lack of continuous exhaust flow. The 'X' on the other hand, creates a smooth continuous flow, equalizing exhaust pressures between both sides with very minimal turbulence. As such, the drone is eliminated and the continuous exhaust flow is back in order. Matt
