please show me a civic with a 90 degree V6 in it. ain't gonna happen and neither wil the sound. a V6 stang sounds nowhere near a civic except to those that think the only "american sound" is a V8

sorry to birst your bubble but the V8 sound is a minority in the world even in america for the last 80 years.

ever hear a GMC I6 from the 50's ? pure sound of power and rightly so. how about a jaguar XKE? or even a Lambo V12. the 3.8 sounds amazingly similar to these esteemed engines.
if you like V8 sound then you have a small mind. i can throw Force mufflers or Flowmasters on a 265" pontiac or a 260 olds and it will sound identical to your precious powerfull V8 musclecar but they srill only had 120hp.

to the topic at hand. an X or an H will do nothing for power on an even fire V6 like the 3.8 ford. however the X makes a nice sound but so does a diviorced dual setup like your uncle is suggesting.
i say let him do it but delete the rear cats on each side and use Force proseries muflers from www.jegs.com or www.summitracing.com

part#'s are FRC-5202 for 2.5" Force mufflers from summit and 395-5202 from Jegs.

$33/muffler with excellent quality and IMO better sound than a Flowmaster 40 costing $70-$80/muffler cant be beat.

like i said let your uncle do the exhauct the way he wants except for the rear cats and Force mufflers. you will thank me

 

not to go off topic but in your sig i see you have 335ftlbs estimated with a Vortech on a singleport.

exactly what other mods do you have because if it's on a stock engine then it's more like 240ftlbs

 

Trust me, he doesn't have that much, he's just estimating as he hasn't been to the dyno yet. I'm banking on him having 225 rwhp, and 275 or so rear wheel torque. Because I don't even think he's ported his intake yet, I may be wrong, but it's sure not listed on his cardomain page. Not calling you out or anything, but on this forum giving estimates like that is a big no no, don't post that you have something hp/torque wise unless you know you have it, doing so can get you in big trouble.

Onto the topic at hand, x/h pipes do nothing for hp, but differ drastically in sound. Straight pipes tend to be loud, but also have poor sound quality up top (my opinion). H pipes are a little milder, but still loud, but have a little better sound quality up top. X pipes are the mildest sounding, but offer great uptop sound quality.

 

yea i was just guesstimating but ill take it off till i get it dynoed if it makes ya feel better. lol. true its probably about 240lb tq tothe rearnow on only 4lbs of boost. Thats what vortech lists anyway so thats only thing i can really compare to for sure. so i figured 12lbs with appropriate fuel and tuning should be pretty high up there. maybe im way off but ill leave it out till i know for sure. thanks for the thoughts though guys.

 

Dude seriously lol.. his v6 sounds terribly rice.

 

Yeah I know a guy with true duals, true meaning two individual pipes, no crossover whatsoever. My car was twice as loud with the mac y-duals. I'm dying to find out how the o/r X will sound.....especially with the Terminator take-offs. Though I think those will mellow it out too far. Here's hopin for the best.

Also, let me add that, atleast in my experience (comparatively limited though it is) the 6 likes back pressure. I dynoed after hacking the exhaust off at the Y pipe (wouldn't fit back on with the IRS in place) and lost some 7 hp and equivalent torque. Sounds pretty damn sick though. Especially wide-open echoing underneath the car.

 

will our cars still pass emission with the rear cats removed?

 

Probably not.

 

it probably will. if they do the OBDII test like they are supposed to, it will. for the simple reason that the rear cats are behind the O2 sensors, and they cannot read if they are there or not

 

@ 4psi he is at best 160rwhp/220torque

an 11psi procharger will lay down 230rwhp/270ftlbs to 250rwhp/290ftlbs

also if he wants to run 12psi on the vortech he had better run an intercooler or tuning will be near impossible even with 42lb squirters
