If I dump my exhaust will it sound any different from outside of my car? Will it give me any performance gains? Right now I have a cat back flowmast but I plan on getting bbk long tubes and mid pipe in the future.

I had flowmasters and dumps. It is louder but the bigger change is the frequency is lower, more of a louder rumble than with tail pipes. You can make a decent set of dumps by cutting off a curved piece of an old tail pipe if you want to try it first.

I liked the sound of dumps for about a month and went back to tail pipes. The fumes were tolerable but annoying too.

back pressure is your friend

Going dumped wouldn't get rid of back pressure. What are u saying ^

doesnt get rid of it but straight pipes are more.

there for straight pipes > dumps

I am saying straight pipes produce more back pressure. In less i am wrong?

horribly wrong straight pipes dont give back pressure, and i think hes talking about dumping it after his muffs not before them

Thats what i'm talking about, after muffs

[flattusmaximus78]

Dumps mean cutting the exhaust off right after the mufflers.

No mufflers means no back pressure, which means slow....

I am not wrong i have dumps on my car now and they need to go for straight pipes to give more back pressure.

It gives more back pressure because it is a longer flow

wait dumps aren't when the exhaust pipes fold down towards the ground right after the mufflers?

yeah thats dumps

Backpressure is not needed on a EFI engine with o2 sensors, it is more of a myth than anything. Proper exhaust scavenging is what you want with a properly tuned exhaust.

dumps suck, I cant wait for my tailpipes to come they are on back order through summit

dumps = fumes+ heat + cant hear any thing inside the car and I dont think they are as loud from outside the car

what is EFI? sorry just trying to learn hehe

[fogged306]

Electronic Fuel Injection

You haven't heard annoying until you run no cats with flow masters and no turn downs. It sounded good for about a day. I never drove a car and get a headache after. it was so annoying i couldn't stand it. I put turn downs on it the next day. I drove it like that for a while.
