can u make an fbody sound like a vette?
I'm with full force on this one. Its all in the pipes. Ever wonder why a 5.0 and a 4.6 sound pretty much the exact same? Well, Im pretty sure that the boddies are different between a late 80's 5.0 and a late 90's 4.6...
and I'm pretty sure that those are two entirely different engines. Now, you can put the exact same muffler on a F150 and it will sound like a truck. Why? Because of the pipes (to include manifolds).
Remove the engines from the vehicles and hook up all the exhausts and start them up. You're going to notice some differences, like how the vette doesnt merge into one 3" pipe and rasp its way into one dual outlet muffler... but instead travel down a nice path to some very expensive mufflers. One sounds like a camaro... like all 4th gen camaros, and the other sounds like a vette (which can have a formula 1 sound to it... listen to the pacecar edition mufflers)

thanks choco... i understand i cant make the bends the same as the vette i have a comp cam to start with so it has nothing to do with the years for me .... i have hooker longtubes which you are right... they arent equal length on both sides....but i have continued the 3" from the collector all the way to the dumps...i know the headers are different (bends shape length) which do contribute but i have the same motor as the 98 ls1 vette so shouldnt the sound be somewhat similar with the same sized x piping and resonators. i dont have the same bends as the vette does behind the bumper and im going under axle vs. the vette over the irs... and i will be putting the stingers right before the tips like the vette...thank god that i dont have rasp!! the rasp i believe comes from the y pipe where the exhaust gasses merge against each other at the Y and the rasp comes from the pressure of the two pipes deflecting against where they meet each other not the chassis.... now exhaust does have a resonation off the chassis like you said but im describing behind the car sound....

The thing you're forgetting is that when Ford set out to make the Mustang, they actually spent R&D trying to get the cars to sound similar. For instance, with the new 3V GT's, Ford spent hours upon hours and tons of money designing the chassis, exhaust and motor to get it to have that "Mustang sound." GM never designed the F-body to have "Corvette sound." In fact, there is no stereotypical "Corvette sound" in the same way there is that well-defined, stereotypical "Mustang sound." Even with all the R&D that Ford put in, I can STILL tell the difference between a 5.0L and a 4.6L GT blindfolded with a cotton ball in one ear.
For some reason, I get the feeling that you haven't pulled the motor and exhaust out of a Corvette and F-body chassis, sat them side-by-side out of the bodies, started them up next to each other and listened for differences. My gut just tells me you're making stuff up, here.

One of the times i was at the dragstrip I asked the kid what his exhaust set up was. He has C5 Corvette with heads and cam, american racing headers, high flow cats into a borla XR-1 Straight pipe exhaust. It was the best sounding vette i had ever heard. Reason why there were no mufflers. I wanted that sound, but the only way to get it, is to go out and buy a vette and get the same exhaust setup.

Stock wise, a vette has shorty style headers, high flow cats (touted by GM to be as close to free flow as you can get with a cat), shorter piping from exhaust to tip and different mufflers. Also equal length for the most part.
On an f-body, the exhaust manifolds were terrible, the cats flowed decent, the piping was longer and went to a y had more bends and the muffler was completely different.
Even if you do a cat back, the manifolds will dictate the sound characteristic a lot. If you had a vette and f-body and went with longtubes, identical cats and mufflers, then the longtubes routing and bends would alter the sound along with the longer pipe routing to change the sound enough. Each bend and angle will reflect the sound differently despite identical motors.

I think this new slp exhaust sounds like a c6 z06 with headers and corsa that i rode in. Especially in the second clip. Just my opinion. Its pretty expensive but sounds damn good.

Strange thread, This difference in the sound is the Z has higher compression and a cam. Do that to your car and it will most likly sound better that the Z did.
I personally think the F-bodys sound more like mussel cars than the Vettes do. I have Kooks and an borla XR-1. I've never herd my car from the outside while going down the road. I have herd F-Bodys W/ cams and other work as I drove near them and I think they sound great. More like a hot rod. I love my car and I love Vettes, but I've often wondered why the F-bodys (with motor work) sounded b

etter Yeah it is two mufflers or resonators at the back. No middle one. Its pretty obvious that that car has alot done to it. But damn does it sound good. I just dont want to have to part with my CME to get my car to sound like that.
