I have a 68 mustang with a 289. It idles nicely and was wondering if anyone had some suggestions for some good exhaust and what size pipe?
Thank you

 

My buddies 68 289 has flowmasters with 2.5" pipe. Dumped over the rear axle. Sounds good to me and him maybe I can get a vid of it sometime.

 

What series? Yeah I've been back and forth with flowmaster and magnaflow

 

I'll ask him. Pretty sure they were 44s

 

Classic combo! Also dont forget a connection in the intermediate area (X or H).

 

Nice, these are some good suggestions that I will take into close consideration. Hopefully within this month I'll get em done.
Thanks

 

What exhaust produces the best engine note for a deep rumble and throaty growl sounds on the 289?

 

it`s what you like not us .. there are dozens of exhaust makers out there .. the best i`ve ever heard was borla .. but i use flowmaster ..

 

I love Borla and Roush, have Roush on mine. Flowmasters for me are overdone and not good sounding. But I wouldn't go over 2.5" pipes, 2 1/4-2.5" are good sizes.

 

I went with the magnaflow on mine and regret it. I am going to change over to flowmaster 44's this winter. I have flowmasters on my F150 and on my wifes new 2011 Edge and they sound great, nice rumble. The magna flow is not deep enough.
