ok, I have a stock? exhuast right now, on my 90 GTU, would it be possible to pick up a RB roadrace header, and run custom 2.5" piping to my existing mufflers? I say "stock?" because it should be all original parts, but my mufflers say "dynomax" on them, which means possibly someone replaced them at some point. My purpose for asking is, a roadrace header is $200 from mazdatrix, which is good, while a full dual exhuast is $1250 which is bad, if I can use my existing mufflers (at least for a while, till I get bored, and want to change that as well) for $200 plus the cost of some custom piping, then a dual exhuast may be in my near future https://www.nopistons.com/forums/pub...DIR#>/wink.png

sell ur gtu and buy a t2

ahhh, if only, well, I may be getting either a tII in addition to my gtu, or maybe just a tII engine and assorted parts, got to go see a man about an rx7 graveyard https://www.nopistons.com/forums/pub...IR#>/smile.png

It can be done, but it will be very loud without any presilencers.

luckily I am in the land of "nobody cares" no emissions inspections, and hondas, and mustangs and all manner of mulletmobiles drive around with no mufflers at all

not to mention, wouldn't my ordinary stock mufflers quiet it down a bit? If they are stock, still not sure about that.



edit: they are very quiet though, at least I think so, can't hear my car over the stereo ever anyway

See how it sounds. Maybe it won't be too bad.

It'll be WAY loud. I have 2 pre-silencers (one for front rotor, one for rear), and it is SO loud.

Oh, Dynomax are aftermarket mufflers

shame then, cause my car is uber quiet, and (in my opinion) very slow oh well, maybe my cat is clogged up, time for a loud ass exhuast.

Your GTU is gonna seem slow if you hang out w/ UniqueTII all the time, lol. The power between the NAs and turbo is night and day...its what made me do my swap in the first place...I loved my NA body and interior..it USED to be perfect and I grew partial to it...but I wanted the turbo power...so I put two together and now I'm an SE-X master https://www.nopistons.com/forums/pub...IR#>/smile.png
