JSM Posted April 13, 2016 Share Posted April 13, 2016 I just installed this and must say the install was breeze. Everything fit like a glove to their header on my 71. http://www.thezstore.com/page/TZS/PROD/classic19k/15-6021 Only complaint was trying to find the center hanger for the exhaust. Ended up having to rig it a bit. Quote Link to comment Share on other sites More sharing options...
jacky4566 Posted April 13, 2016 Share Posted April 13, 2016 Been eyeing this kit. Could you post a video with details on the car? Does the kit just 'stick' together or is there welding required? How do the pipes stay together? I really wish they offered this with a twin tip muffler. Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted April 13, 2016 Share Posted April 13, 2016 It sticks together with The U clamps. Ideally you'd weld t together with vbands or something (actually that would be my preference). Pretty sure it disconnects close to the muffler so you could do anything you want from that point on. Quote Link to comment Share on other sites More sharing options...
HuD 91gt Posted May 3, 2016 Share Posted May 3, 2016 I'm happy with the kit. Kit pretty well too out of the box. I purchased the "Premium kit". Quote Link to comment Share on other sites More sharing options...
princejqman Posted July 19, 2017 Share Posted July 19, 2017 (edited) I also purchased the MSA PREMIUM EXHAUST for Stock Manifold kit and have been experiencing loud popping at the exhaust on deceleration when lifting the gas pedal on 2nd and 3rd gear. I retarded the timing from 15 to 12 btdc and then to 10 btdc and the issue is still present. It came with an Xcelerator Turbo Muffler, downpipe tuve and 2.5 diameter aluminum pipes. I have a Schneider 274F camshaft and have Heard that people with the stock camshaft have no issues whatsoever. This is really strange as i used to have the MSA TWICE PIPES kit and never experienced any deceleration popping.

theczechone Posted July 20, 2017 Share Posted July 20, 2017 i don't think this is caused by the exhaust and it is quite common on large diameter exhaust with no resonator. My 3.1L stroker motor with a 3" diameter exhaust and a hooker chambered muffler popped like crazy when i tip out of the throttle. what happens is that a bunch of unburned gasoline ends up in the exhaust and self ignites, at least my theory Quote Link to comment Share on other sites More sharing options...
princejqman Posted July 20, 2017 Share Posted July 20, 2017 What resonator or glasspack is recommended to eliminate the deceleration popping on this MSA PREMIUM EXHAUST? I called MSA and they dont sell this resonator. I just cant stand the popping but do like the drone! Quote Link to comment Share on other sites More sharing options...
HuD 91gt Posted July 21, 2017 Share Posted July 21, 2017 (edited) I put a resonator in my system and it just makes it a little quieter The popping comes from your fuel mixtures. Enhanced by your cam which is less emission sensitive I'm sure. You may not have this issue with the twice pipes, as the exhaust pulses are split between the pipes. Each pulse is alternating between each separate exhaust system. My own theory at least. What are you using for carburetors. Stock needles or modified for your cam?

JSM Posted July 21, 2017 Author Share Posted July 21, 2017 I do have headers. Actually, not long ago I was experiencing popping too. Got worse and worse. I tried adjusting the carbs and it did nothing. Put new plugs in as I didn't recall if they had been done since I bought the car back. No more popping.

princejqman Posted July 21, 2017 Share Posted July 21, 2017 I am using ngk BP6ES which is the recommedable one! gapped at .032 and still get that popping on deceleration. i have also adjusted the carb and carb floats and nothing!! Would a 2.5" resonator solve this issue? Quote Link to comment Share on other sites More sharing options...
