RB Road Race Header
8" long collector into 3" Pipe
3" Spintech "muffler"
3" pipe to a 3" Series 40 Flowmaster

This is LOUDER than a CORKSPORT ever dreamed of being.

Oh well a couple hours of cutting and welding down the tubes. Back to the shop for more experimentiing

 

What's wrong with being loud eh?

mine is:
Road Race Header
two pipes into two spintech "mufflers"
slight bit of pipe after that, few inches, that dumps...right before the axle...

at cruising speeds, with my radio up as far as it goes, I still hear the damn thing...anybody wanna buy it??

 

hahaha

me me me



just kidding my cb has a million holes in it already, i need new one asap, but no money after my rebuild..

 

Banzi trust me his is WAYYYY louder! The spintech mufflers really don't do much muffleing, and I would never suggest for anyone to buy them, unless you buy a truck/RV, because they are supposed to be the quitest. But they are built VERY nice, and give pretty much little if any back pressure, I suppose that would be good for turbo cars, but not great fot NA's. I wish I would have know that before I built the one on AE_racers car.

Also for everyone that said that exaust wouldn't last longer that 1 week, AE_racer your gonna have to tell how it's holding up.

 

Why are you going with 3" piping on an NA?

 

good question, arent NAs suppose to be like 2.5"?

 

i know spintech mufflers will hold up cuz there a completely different design... i will say one thing tho... the only thing there good for is V8s!!!!! i used to be into honda tuning.... they gave us a free 2.5 inch mandrel bent exhaust with a spintech muffler for an integra type R... with stock exhaust , jdm itr header, aem CAI it dyno'd at 177 pretty strong for an ITR... with spintech exhaust and highflow cat.... ( same day dyno.... took the exhaust off put the spintech one on ) the car dyno'd at 170 flat.... =\ the muffler design i think is only good for v8's or that sort cuz they put out awesome numbers on those big v8's.... anyways if you think im bs'ing i beleive the owners name is Chris Anderson... or that sort i went to his shop before... well organized cool guy too.... but hte mufflers just dont seem to work on these low displacement cars..

 

I went 3" because I had a 3" spintech and some 3" tubing and mandral bends on the shelf. New parts are on order. These parts will go back on the shelf for future use on another project. I still want to get a dyno run on this combo though.

 

What parts are you looking to play with now? I am curious ast to what combo works best for a na with road race header.

 

on a NA motor, ur supposed to go no bigger then a 2 1/4 in piping, atleast on a piston engine, i dont know how different it would be for a rotary motor though.

 

^read 2 posts above.

 

The mufflers have lasted well over 2000 miles, and much longer than just a week or two

 

I love the Spintech mufflers. They are designed and built very nicely. I never said they were quiet though! My friend does have 2 of them on a V8 and that is one awesome machine. I guess the rotaries should sick with a muffler that uses some sort of internal packing rather than baffles. I knew it would last longer than 1 week!

 

Would the Rb Road Race Header and The N1 duals from apexi be very load on a NA. Would that sound good?
