if I were to get long tube headers and just go striaght into dual exhaust all the way back, with no converters and not resonator ?
I can tell you about my personal experience. The difference between you & me, is the headers & I have a 2-1-2 Big Dawg, and you want "True Duals" (No X-pipe, or Resonator).thundrburd said:if I were to get long tube headers and just go striaght into dual exhaust all the way back, with no converters and not resonator ?

Are you talking about Drag Pipes WITH or W/O a resonator?BlownV6 said:I'm wondering how drag pipes would sound with the stock exhaust.

I intend to use a boost activated 3" exhaust dump from ATP Turbo. http://www.atpturbo.com/Merchant2/m...OD&Product_Code=ATP-ACS-010&Category_Code=BCS So at about 5 or 6 pounds of boost it will have open exhaust resonator only and below that stock exhaust. What do you think? Catch you later, Bob.
I think that as you have drawn your concept, your "stock" exhaust will be stickking straight out from under your drivers door. I'm sure the drivers in oncoming traffic won't mind having to drive off the road, to avoid your "stock" exhaust sticking 8 feet out from the side of your car.bloodybobber said:A full open exhaust under boost and a quiet exhaust for crusing.

LOL...............I don't think that even Superman would attempt porting exhaust manifolds on the car.thundrburd said:is porting the stock manifolds something that they can do on the car, or do they have to take them off to do it ?? and what size tubes should I run back from there ?

But on a serious note, your exhaust slamming straight into your cutout, will cause reversion pulses which will try to travel back to the engine, causing backpressure. Your idea will require 3 more 90 degree bends to hook up with the OEM exhaust, which is straight behind your cut out.
If you absolutely MUST have an exhaust cut out, there are much better ways of doing it, and none of them are Cheap. Oh, it's a good thing you have an auto, cuz your 5-6 lb. boost idea will not work well with a 5-spd!!!
I agree with Uncle Dave. An SCP 2-1-2 Little Dog will probably work better, and be cheaper to build.

bloodybobber said:you are right, I took another look as I was working from memory. I knew the exhaust did a 90 to the drivers side to go around the gas tank right after the resonator but forgot how close it was. As for the oost point that would be adjustable with a manual boost controller
David the boost controller will only control the point at which the dump would open, not SC boost. A y-pipe would also be the ticket. As for tuning since the dump point could be planned on it could be tuned for where a manual dump would require a switch chip. In my old age I like a quiet cruise but if I call on all the ponies noise is a feel good. I have a 5.0 Mustang with flowmasters and it is just too loud to be a daily driver. I am already having hearing loss and tinnitus so the stock exhaust is nice but I understand the need for low backpressure at boost. Catch you later, bob.David Neibert said:You can't use a boost controller on an SC. Boost is dictated by the pulley diameter and how much air your motor and exhaust flows.
