Does anyone know of a muffler company that makes a "race" muffler with a 3" straight through ID? I'm getting my car ready for emissions, and I'm changing my exhaust set up. Thanks.

 

The Borla XR-1 mufflers would be ok. They're only about $130. Summit sells them:

Cool. What about HKS or Greddy, or are all of their mufflers 2 1/2" ID? **** I've already spent $200 on this new exhaust, and I have not gotten my cat. conv., muffler, or pre-silencers. Damn!

 

You can get an Apex-i N1 muffler, but it's only 2 1/2".

 

Dynomax

flowmaster probably do...

not sure on the sound of those on a rotary but they are performance mufflers....



SWEET MY POSTS ARE 302!!!! 5.0 BABY!!







ok ok 4.9 shaddup!

 

i wouldn't use a dynomax it won't last long under HOT rotary heat......

 

Well the dynomax on my 2.3 has performed great... but that motor almost runs too cold!



Will most likely be putting Dynomax Ultra flo's on my 5.0....

 

The dynomax mufflers are not a straight through design, are they? They recomend using a muffler with a straight through design on the rx7s.

 

I believe the Ultra flo's are pretty much straight through..

Dont know but they can come in welded ss cases..

they are what I want...

They are recommended for Mustangs running X pipes and I want to run x pipes....

 

x-pipes are cool
