3" or 2.5" catback

[mgwarrior350]

I currently have a 2.5" catback with magnapacks installed. On top of that I have intake, mopar long tubes, catless mids and a tune. Is it worth it for me to buy a 3" exhaust or just save the money and keep the 2.5. Also will the sound be difference be noticeable.

I'm not sure but I also have the molar long tubes with magnaflow 2.5"

I am upgrading to a 3" from the headers back I hope there is a sound difference

 

[mgwarrior350]

let me know how it sounds, how do you like you mopars

More are in, more are out.

so the gains are worth the money with the catback

Unless you do some heavy modding I would save $$ and keep the 2.5"....

Only you can answer that question.

If you do install a 3" system, purchase an X-pipe or H-pipe too and go true duals.

I picked up 9 HP and 15 Tq on my hemi with that mod top end. Don't know what I did with the SRT-10, didn't do a before and after dyno. (I'm sure even more, but can't verify it.)

I can buy myself a bolt on magnaflow or do the 3" myself any opinions on that and if I go the custom route any mufflers recommended

Local vendor here or Aeroturbine.

sounds good so its worth it to just do it all myself?

 

[Troy's QC SRT]

where are you guys getting the H/X pipe from or are you just having your exhaust shop make it? whats the difference between the two?

 

[Yellow venom]

I'm only taking a guess,but I'm thinking to switch from 2.5 to 3" the gain will be next to not noticable(maybe a couple HP),if 3" was a whole lot better I'm sure Mopar would have made their headers with 3" collectors and Im sure they spent a few bucks on testing to see with what works? JMO.

i built my own 3" exhaust on the hemi...

cost me barely over $100

7ft pipe section- $40 new
bullet mufller and turndown- $40 new
heat tape, muffler mount, - $25

had a friend with a welder (and band-aids haha)
i like the 3" exhaust better.


I still have 5.5ft of that pipe if you want to buy it,
