calling all exhaust smarties

[SLOWBRAEATER]

since my longtubes are goofy, meaning the drivers one has a 90* bend in it do you think its a good idea to run a true dual setup with regular headers? or is true duals with x pipe basically for longtubes? if i got regular headers and ran a y pipe setup with a borla or triflow exhaust do you think that the y pipe/ borla setup would sound better than the regular headers/ true dual setup with x pipe and bullets? or will the regular headers with true duals sound better than the y pipe setup? do you think my 1/4 mile times would be just as good with regular headers and the true duals with x pipe, as it would be with the longtubes with true duals and x pipe? or would the longtubes with true duals give me alot better et? it shouldnt be any better i mean the longtubes are only like 8-10" longer

That's a lot of questions... [img]smile.gif[/img]

I don't know about the sound difference.

Long tubes tend to help a little more at the track, with the v8's anyway. I would think so on the v6's, but it's probably not a whole lot. The length has to do with techy stuff like gas pulses and reversion and stuff like that. The 8"-10" makes a difference in that world.

Properly sized duals with an x or h, vs. a properly sized single should flow about the same.

Longtubes are more for help on the top end. Is there a possibility to re design the header that doesn't make a 90* turn? If you can, then I'd try that.

those headers to 2.5" Y pipe, 3", etc...
or, go tru duals, with bulletts, since they will fit.
an X pipe will help balance the flow of exhaust gases. It can be done, you're just going to lose some ground clearance. But, there shouldn't be a huge issue, just don't jump curves or go up really steep driveways. I'm *kind of* slackingly working on some long tubes myself, but really, you can do duals. Headers --> X pipe --> bullets

Go with the tru duals except go with an H-pipe instead of an X.

[SLOWBRAEATER]

why would you say go for an h instead of an x? an h gives power downlow an x gives power through the entire rpm range.

i'd go with a mandrel bent x pipe, it'll provide for lots of scaveging for down low torque and free flow for high end
