Exclamation exhaust help

i have a 2001 v6 and recently got into the exhaust thing. i installed mac long tubes with custom mid pipes going straight back (not x or h, just straight), no cats, roush side exit exhaust. i just got the car back today and it sounds like a honda civic with a fartcan on it and i do not know what to do. i just don't have all of the knowledge of everything to fix this and make it sound a bit more muscle-like. my first guess is that the mufflers are no good and i need to get new ones. the mufflers on there now are roush and i bought them from a guy who took them off of a '99 gt. any help to get the sound better would be really appreciated. thanks in advance.

You could try mufflers, but you're pretty much screwed. The cats would help, but you really need to go back over to the full exhaust system to get rid of the sound. I have LT's with pre axle exit, and I have the same problem......

after driving it the past couple of days, it's not as bad as i initially thought. once it gets around 3400 RPMs, it starts to really scream like a rice burner, especially when i am getting on it pretty good. from idle to that, it doesn't sound too bad, which i guess is good for me since it will save me fuel. . but, i talked to a guy today and he said glasspacks and/or magnaflow mufflers would deepen the tone quite a bit, but i'm debating (after the last 3 weeks and around $200 spent) taking off the roush exhaust/side skirts, selling that, buying flowmaster super 44's or super 40's (and stock skirts of course). would this be the better option for the muscle-ish sound i'm looking for???

the only thing I could think of that "might" help is putting a crossover (like an "h") across your straight pipes.

i talked to a couple people and they said it would help a little bit but not a whole lot. i might have one put in there though...i think anything would make it sound better.

You have to use a H-pipe not for performance reasons, but to get rid of the rattling high rpm's sound. That will help a lot. Then get something like a flowmaster or MAC mufflers. But really the only way a v6 ever sounds good is when it's been stroked, cammed, and everything ported. And even then it sounds like a throaty v6.

Man , you might actually check into getting stock GT mufflers , it would really quiten it down a bit , plus v6's really need an H pipe to even out the sound

V6s actually dont need a crossover due to the fireing order, it just changes teh sound

Been down that road. I have had over 5 different exhaust setups, you need to put high flow cats on. That will get rid of that rice sound.

Typical 97 vert with 8-point roll bar.

I used a couple 14416 maganflows (4" round 2.5" in/out). They sounded way too lound and like crap (ricey).

Thats with headers and hi-flow cats
My 2 cents.

Thats what im running, but i dont have an H pipe. Also the reason why your car sounds bad, is because you have no cats. Buy some hi flows or something. It might get rid of the raspyness

the flowmasters came in today. we were going to put them on but after looking at the exhaust, we're going to take it up to my dads fab shop sometime in the next couple of days and weld it all together.

those flows are a LOT beefier than the roush mufflers that are on there. it's like comparing a chevy cavalier to a dodge hemi truck hahaha.
