I have a 08 sedan stick shift. I don't care about gains just some deep sound. What do u guys suggest. Thanks

If you are "rubbing" the engine, you're doing it wrong! lol

I would rub it with something that will make a lot of noise against aluminum. I think for a deep sound you will want to go with a large hollow pipe. The thickness of the pipe wall will change the sound some, so you will want to experiment. You may have to tap more than rub for a deep tone. A deeper tone tuning fork may work if you can find one.

What in the hell is rubbing the engine mean???

I think you should tap it first with a long solid pipe. Then poke it and rub it at the same time. Anyone?

Lol. You guys are funny. Never heard of that huh. I meant when I press the gas. Intake is one of my choices but it will cost around 400. Anything else I could do since all I want is some sound coming out. Thanks

Intake won't make much of a sound difference. You're looking for exhaust

HFC are the way to go if you want a deeper sound

Great choices but I don't want to spend 500 on just sound. Any other cheaper options

rubbing = revving??

Muffler delete = free
