With a collected RB header run a 2.5" pipe to a 3" to the rear no mufflers, no silencer, just for the hell of it? Or for racing purposes(as I'm assuming it would be only slightly too loud for the street )? I was thinking about maybe getting a shop to fab up cheap fat straight pipe from the header the whole length of the car and exit on side of the rear. Am I onto something or am I insane?

 

you are insane. i have rb streetport exhaust and i ran it with just the 2 presilecers. that was loud a hell. i was about 1 and a half miles from my friends house and he could hear me easy.

 

You have a a death wish. A guy I know owns a GSL-SE with a single straight through muffler along, and his exhaust sets off car alarms thousands of feet away.

His car at half a mile sounds like its just pulling up next to you.

Do you think you would get 5 feet, spitting jet flames and making a sound that could crack glass without getting pulled over by a cop? I think not.

That and the fact that the backfiring along would burn the paint off of your car.

 

i have the road race header+two spintech mufflers, then turndowns a few inches after...nah, its not loud

 

I had my NA with headers and a straight 2.5" pipe running out the driver's side exit...yeah, mucho loud.

 

I drove my n/a with JUST a header on the freeway (1 hour drive roundtrip) and I was getting dirty looks from everybody When a cop was near, I would press in the clutch and cruise on by. I dont think none of my neighbors were too happy with me that week. Your setup WILL BE LOUD.

 

if i had a stock manifold and had a massive cherry bomb that went back almost to the back, then had an exhaust shop make me a Y back an put 3inch piping with 2 tips back there, would that be way too loud for street?

 

I'm not aware of anyone who has ever tried it. You might be onto something . . maybe the next big discovery in exhaust performance technology. I say go for it!

 

Why would I be backfiring and burning the paint off the car? I mean to construct a straight pipe that runs in the stock location as a single, with no mufflers or silencer, stock mounting points, exiting the rear of the car, starting at 2.5" and on to 3". And seriously, I have no intention of running this set-up on the street, maybe the drag strip or autocross event just to be annoyingly obnoxious
