ALERT! Sunline Racing makes an aftermarket H pipe for the Nismo as well as the Base. Goes for $700!! I'm buying it if AAM has no plans of moving forward with their H pipe.

$700?!

You can buy a used catback for that price.. seems a little steep for an h pipe

To each his own. Amuse is selling theirs for $2000 and we don't know when exactly AAM will release their product and I am looking to upgrade now!! LOL :happydance:

they have the accompanied straight pipes that lead to the muffler two...

Just a FYI...there is a reason on why I am looking for another H pipe. I have the Sunline H pipe and the flanges are offset...as in not straight.

Wait to the stock midpipe doesn't exactly bolt up to the Sunline H Pipe?

no the flange that connects the H pipe to the bottom of the TP's are welded at an angle. Like someone just welded it and before it cooled put it on the ground and it cooled at an angle.

i didnt even know we had any suitable H-pipe replacement :icon14:

too bad it doesnt have integrated flex pipes

to be honest...most after market systems dont have the flex pipes in there...for the most part, it should be okay. I dont recall if even the stock one had flex sections...meh...old age.

If the flange was straight....I would probably singing another tune. Maybe I just got a bad one since supposedly Sunline is supposed to be a pretty decent company. Maybe they called a fire drill when the person just finished making the one that I got. :p

Silly question... But why an H-pipe? X-pipes, in theory, and in other applications, make more power.

yes we definitely have flex pipes! i feel its pretty necessary to have a flex pipe given how much our engine flex's and twists. the flex pipes are the only place to relieve this. anywho, did you ever complain to sunline? if they really are reputable, they would do something about it!

why does the factory one have sheet metal wrapped around it and clamped at the ends? is it to keep heat in the pipes? sound?

Heat shielding.

right. i believe its on the principal that hotter exhaust gasses flow faster as well.
