WAs the testing done on a N/a car? if thats the case ill just delete the resonators, i just wanted the car to sound loud
What do you mean by single 3"
Yah N/A, it was literally bone stock except for exhaust mods. It had an offrod x pipe, which showed some little gains, and then when he went straight 3" from the x pipe back it lost power.
Hes running a single 3" now, as in the 2 banks merge in a collector and there is a single 3" straight pipe all the way back. Made more power than stock and shaved off a lot of weight.
I think a lo of people are running too much exhaust for their setups.
Unless youre boosted or spraying I think open 3" dual exhaust will kill velocity and hurt power.
like the old school fbodies.
All `98 WS6 and SS's had the single 3.5" pipe Standard unless the SS had the optional SLP Dual Dual exhaust.
In `99 they went to the Dual 2.5" pipes. The single outlet flows better but was to loud so that is why they changed it.
A stock F-body has a single exhaust from the factory. The exhaust from each side of the engine merge together with a y-pipe. The single exhaust pipe continues from the y-pipe, over the axle, to the muffler. The muffler has a single inlet but has two outlets. The two seperate outlets exiting under the rear bumpers give the illusion that the cars have dual exhaust. The factory muffler is very heavy so it is not uncommon to see someone replace it with a lighter muffler with a straight through design using a single tailpipe. This reduces weight, adds horsepower and usually sounds much better than stock.

Yep, but just wait, in a day there will be 20 posts telling us were stupid and that nothing could possibly be better than dual exhaust, because its all about "flow"...
I totally understand that, Im just making a point about not wanting to go too open with the exhaust.
Same diameter as the stock pipes. Even reused my stock tips. It's quiet at idle but once that VCT kicks in, it barks like an old Mopar with turbo tubes!
Still has factory resonators too.
So, when does VCT "kick in"?
Buschur did some testing with deleting the mufflers and resonators and actually lost power, especially down low. Last I saw he was running a single open 3" putting down good numbers.
Without supporting mods you dont want to open up the exhaust too much because it will kill velocity.
In the following I have Magnaflow 15594 muffler deletes
Holy shit...they're proud of their metal aren't they? $$$$
Like the rest of us, I'm looking for the right sound. Just went from Kooks catted with Stingers to Kooks O/R with Stingers and resonators.
Didn't put the resonators on for about two weeks and the car was not as loud as I thought it would be and liked the rough sound, although hated the trumpeting. Just installed the resonators (18") and now the car is quieter (but still loud) and a lot smoother sound, i.e., trumpeting is 100% gone.
Unfortunately I don't like it. It tamed it down too much. Think I'm going to try some muffler deletes if I can find some cheap. Pypes are the cheapest I've found for around $250. Any other options out there?
Their pricing is over the top for sure. Not much better for the Roush equiv.
I had the Pypes Bomb axle backs on my GT500 and loved the way they sound. Just enough to hear and not too loud. Perfect over-the-axle setup IMO.
What happened to him? He was posting on Modular and disappeared after his clutch problems.
His single exhaust interested me.
