yes or no?

 

No imo

NO. *gives the thumbs down. shakes a box of uncle ben's*

 

3-3.5 inch tip. nothing more.

 

dump pipe is THE best look IMHO. I've seen some bomb rx's with dump pipe mufflers and they look amazing. Even Duals on RX-2's........now that is somethin'

 

...my muffler has a 4 inch tip...

 

Behind a rotary its not the size of the muffler that matters,its the quality.

Regardless of the size or brand,if its any fiberglass packed straight through muffler or any cheap baffled type muffler.......,it wont last long with the rotaries extreme heat and strong exhaust pulses/noise going through it.
Typically for an exhaust system,anything over 2.5" is considered overkill on an N/A rotary,and will just increase noise while decreasing ground clearance.Turbo engines can go as big as you want with the exhaust,but 3" will usually be fine for most street vehicles.

Stainless packing material should be considered mandetory to prevent blowout or meltdown.The body/can can be mild steel,but it should be thick and beefy to reduce resonance.
The RB/Primaflow muffler is a perfect example of a properly designed,robust rotary muffler,although many claim its too restrictive.The StreetPort version of that muffler has larger pipes and has flowed enogh air for my 13BT to pump 14psi of boost and make about 300HP. Its lasted for about 5 years now with no signs of failure.....they are pricey,but WELL worth it.

 

i had 2.5" dump pipe with magnaflow prescilencer for a week. really couldnt drive my car tho. wish i had video of how loud it was. could not go anywhere near 3k if i wanted to hear.

 

No thats a bad ricer

 

Exhaust size is relevent to Hp output. Too big of piping and exhaust will hurt performance on low Hp applications. In this case, " Bigger is not alway's Better".

 

^What are you talking about? 6" piping on my stock 12A made my car outrun a helicopter and a 1/2.

 

he is right. we root for you doing a big muffler!

 

What exactly is a dump pipe?

 

As you can see, the original thread starter is a noob trying to get a post count up. Otherwise this would have been a more specific question besides "Big" muffler.
