Straight pipe?
 
Anyone straight pipe a hemi? I know it would be extremely loud and annoying but it would be pretty sick...

I heard possible problems with back pressure but I was also told its wont really effect it. Opinions?

my setup is pretty close to a strait pipe. i'm running a magnaflow 4" round with no resonator side exit, and its stupid loud. anything louder would be too much honestly.maybe look into running an electric cutout, that way you could have it loud when you want and quiet when you dont.

You talking about no cats too? That would be way too loud (sound crappy), imo, although you could annoy those darn harley dudes that run open pipes :D

Cats act like a muffler slightly, so that would help, but just put a nice free flowing muffler and no resonator and it would sound good (somewhat loud) and not just like no mufflers. I hate that sound and I do like noisy engines, lol. I doubt a majority of people can distinguish the level of an engine based on the note though.

Well, I only have the 3.7 V6 with a straight pipe where the muffler was going to the SRT dual exhaust pipes over the axle with the dual resinators and dual tips, and its def noticable when im driving around. With just a straight pipe on a Hemi, no muffler or resinator I would think it would be insanely loud and after a week you would hate it. Why not go with a straight thru muffler to try out to see how you like it? From what your saying I bet you would prob be happy with a Flowmaster. My cousin has a Flowmaster on his V8 Tundra and I can tell he pulled onto my street just from the sound, but it sounds good, not like a car with a rusted out exhaust.

I have read on here a few people that could not stand the sound inside without having resinators on there Hemi's. The cats should be left on, unless he is looking for every bit of power from his motor. No reason to remove the Cats on a daily driver, plus might not pass inspection like here in MA.

yeah, I've read that also and my experience so far is it actually sounds better without the resonator...Least with this magnaflow it already had on it. I personally hated the magnaflow at first, as it had that darn hum sound (reminded me of my friend's 2-door Tahoe 5.7 he had) and drove me nuts. I chopped that resonator off and while it's a hair louder, IMO it sounds 100X better. I can actually distinguish the note. It is a little on the loud side inside, but I wouldn't call it drone as much as magnaflow hum. On the highway, it's not bad...just when you first get on it.

ps - have you felt have heavy that resonator is! Another benefit, I guess :)

Yea, that is loud. But I think alot has to do with where the vids were taken. My exhaust sounds like a jet engine going thru the callahan tunnel also.

Sounds like the 2010 SRT8 I test drove on the highway last weekend, open roads.
