I´l buy it.,..

 

3" x 2.5", over the axle with sweet thunders.....

 

it all depends on price..bassani makes some now, but its priced at 1k....and is only or stock manifolds...unless you modify it.

 

3 inch x with 3inch over axle, probably oval exhaust tips

 

ditto... i'd be all over it

 

I think a true dual kit, 3" to the X and then dual 2.5's both down the passenger side would be the best bet. You can just barely fit the dual 2.5s through the stock uppper PHB, although if you could fab up an inexpensive replacement piece, that would be even better. Offer your choice of mufflers (bullets, spiral flows, sweet thunders) and youd have a hot selling item.

 

Actually, how about a backward Y pipe that mates to an existing Y pipe (you may have to shorten the collector). Now youve got an X pipe and youre already in line to shoot right down the pass side of the driveshaft tunnel. Go up and over the axle and split back to each side through the mufflers of your choice. Wouldnt be too expensive, and would offer a true dual conversion for those that already have Y pipes.

 

I want something that will withstand F2-r and 454ci.

 

Can you buy true duals in "sewer pipe" size?

 

3x3; I'd swap my LM for that, but I'd have to (yuk) find some mufflers for it... I've had the LM so long, that I don't know if could get used to mufflers again. ...maybe just straight pipes to 3" slash tips

 

I dont see anyone in this thread so far that can make use of a dual 3"X3" set up. It looks like everyone thinks the bigger is better rule applys to exhaust, the 2.5 out the back will support the needs of all but the most radical set up. Im making 570 to the ground and the dual 3" to 2.5 would be more than enough to support my needs, I would acually expect to lose a little low end power. I am interested more for the sound than any extra power I might gain.

I vote for the 3" to 2.5 set up, and yes I would be a buyer if its nicely done.

 

Just a good 6" would do the trick wouldn't you think?

 

I might be interested in an over the axle setup as well, without tips though, I have my own.

Clearance would be the major concern though.

 

3" and 2.5" over the axel for clearance issues. however, i'd NEVER buy an X-pipe true dual system. H-pipe all the way. there's no point in an X-pipe IMO. it makes less average power across the entire curve and doesn't sound nearly as good, not to mention drones worse. most of the guys with X-pipes probably can't even give a reason why they went with an X-pipe other than most of the people with TD setups have it. that is NOT a good reason.

 

where'd you get your info^ i thought x pipes were better for power and sound production...but im only half right acourding to this.

this is from a sticky -
What to look for: Your only actual viable option is an X pipe or H pipe. Which is better will always be debated. Most people go with an X pipe, in a nutshell an X-pipe will net you more power and torque and an H-pipe will have a slightly better sound. Both are great, so choose what you like, either is better then a traditional Y setup. Where duals shine is power under the curve.

 

an X-pipe is good for peak horsepower. an X-pipe will give you better DYNO NUMBERS, but an H-pipe will give you more real-world power under the curve where you spend most of your time. that statement from the sticky is actually plagued with errors. i've seen dyno graphs showing that H-pipes actually net much more power than X-pipes along the entire RPM range. also H-pipe for sound is also an opinionated statement. not everyone will like the sound of an H-pipe better. "good sound" is not definable. i'm sure there are people out there that think civics with a fart can sound great.

take that sticky with a grain of salt. 9 out of 10 people on this site with true duals have an X-pipe. what do you think is going to get recommended more and praised more? "the best exhaust is the one you have," remember that. very few are honest and actually research this stuff. most just jump on the bandwagon and get whatever everyone else has. look at the new flowmaster single chamber fad. a few months ago, a handful of people on this site had them and most people didn't even know what they were. now everyone wants single chambers. take it all with a grain of salt.

 

good points.

 

3x3 here with a powerstick or 1 chambers, bullets have no tone

 

3" X to 2.5" over the axle with XR-1s.

Most likely it would have to be 2.5 to go over the axle.

 

He makes **** up.
