The thing is that the Dynomax muffler might not resist the heat\pulses from the engine when placed as a mp.

BoneT2&Harmony 03-27-2005 08:08 PM

it says on the box it can resist 1900 degrees, besides im running that shiny one before it.

Dynomax is a waste of money for a rotary or anything else for that matter.

BoneT2&Harmony 03-28-2005 06:26 AM

well i dont think the TGT will be 1800 AFTER the presilencer. i dunno i'll see. and if it fucks up it has a warranty https://www.nopistons.com/forums/pub...IR#>/smile.png

The round ultraflow muffler will work without issues as a muffler all the way back in the catback.

Well, one thing is what it says on the box, and another what it will hold. Even with the warranty, *I* would rather do it once, and only once; since is your setup, as long as you are happy with it, and don't mind replacing it (if you have to), then is all good.

im about to find out

MPM 03-30-2005 01:34 PM

I had a resonator like that polished one and it did absolutely nothing to quiet'n down my car. As far as I'm concerned I wasted $30 on it.

BoneT2&Harmony 03-31-2005 04:39 AM

that presilencer is from the ssautochrome exhaust. ppl say it does quiet down, but not by much. maybe because its single. but mine is 3" dual all the way (GP Sports exhaust)

SPD Racing FC 03-31-2005 06:12 PM

on my n/a i run rb header to bonez cat to morosr sprial flow to a no name muffler, it sounds like a rx8 with a exhaust

I guess internally its different but externally they look identical. This is a case where size does matter https://www.nopistons.com/forums/pub...#>/biggrin.png



I'm probably going single on my car but I'll be using a Racing Beat right side turbo muffler and a Magnaflow 4" resonator between the presilencer and RB muffler.
