I just got the megan racing s-pipe and it wont bolt up to the factory mid-pipe. Has anyone else had this problem? I dont know if its a good idea to cut off the pipe sticking past the flange that bolts up to the mid-pipe or not

 

What??!! hey man check to see what "S pipe"you bought...
there are 2, one is the S pipe that bolts on to the rear part of the MID pipe, AND then theres the S pipe which is really the DOWN pipe that bolts in between the "header" and the MID pipe.

 

i bought the down pipe not the mid pipe.

 

The pipe itself sticks out past the flange. It will not slide into the stock mid pipe so the two flanges wont bolt together.

 

your gonna kick yourself...
flip the stupid thing OVER!!
wait no what are you talking about the Down pipe shouldn't have any pipe sticking past nothing.
one end should have a "inverted" flange for the flex flange and the other a straight flat flange.

 

i dont think its backwards because the gasket from the header fits right into the pipe like it should.

 

OOH then you might have a messed up one were they accidently welded the flange to far back...
send it back! or if you cut it will it still reach the mid pipe?

 

I gotta go bro, but it deff sounds like you have a messed up down pipe
prob a machine error. its up to you... send back or risk cutting BUT once you do its yours regardless that it was a manufactures defect.
choose wisely...

 

Yea I think it will. I just wanted to make sure it will still seal right by cutting it off and if it was welded on to far back. Do you have it installed on your car?

 

Naw I have an INVIDIA a thing of beauty lol
I was just trying to help you out.

 

Thanks for the help. I think I might call them up and see what they say.

 

I have a megan s-pipe and it was a tight fit. It's def not in the same position as the stock one. i had to push it up more into the bottom of the car but it all worked out....

 

i want a megan, but invidia is some good sh*&..how do you like yours?

 

Its probably the biggest of the Down pippes for the TC, the first batch had the O2 bung in the same spot as the stock and caused some problems fitting the antifouler mods for those with a header, BUT i think that was either fixed or no longer an issue with the 07 tc's slightly different manifold.

its great though a bit over kill. great fitment and it doesn't hang too low like i hear the ZPI one does.

 

mugetsu: what exhaust mods do you have then? the invidia Spipe....and is it raspy?

 

I have WR SRI which i'm switching this weekend for a Bo Bo 2.75" ebay CAI. LOL gonna give that a try. Alpha Header/Invidia down pipe/ and Tsudo N1 cat back.
I'm running this thing "inside" my mid pipe called a CC insert, which its basically a resonated velocity stack, it brings down sound levels by 5 to 7 decibles and kills rasp. And only creates a very small bit of back pressure, and considering i'm pretty much running an straight through exhaust that lil bit of back pressure is welcomed.

so with the combination of the insert and the 18" resonator and 10" canister muffler on the tsudo, my car sounds pretty good, it has avery agressive roar at start up then a low growl at idle a medium growl at partiall throttle and a loud roar at WOT.

I think i might have 2 small leaks 1 on both of the flex joint flanges (i'm using both stock gaskets) that open up briefly on hard throttle and give me a lil bit of rasp when i gun it.

i'm also going under there this weekend with a tube of RTV red compound to make a quarter or half an inch seat under both donut gaskets to see if this will take care of the leaks. Only then will i know if my exhaust is trully rasp free.

another reason i'm looking forward to switching the SRI with a CAI is that the WR gets really loud at WOT around 5 to 6K i mean it rumbles to the point that it rattles the change in my ashtray and actually vibrates the whole front dash.

 

was wondering can you give a pic on the CC insert? Am in need for something to lower the db on my tanabe concept g. its too deep for me and want to try it out before i get a second resonator.

 

Are you serious bro?! do you have a header and S pipe? or just the tanabe axleback?
The tanabe concept G is prob the closest to greddy's evo2 which i had on a stock exhaust manifold and pipe, its prob a tad bit loud at WOT but nothing that would alert the cops.

any who the inserts are originally made for domestic muscle cars and track use, they have to be welded on, mine works as a bolt on for my set up because the tsudo mid pipe uses a 3 bolt flange and they make an insert that is made for headers that use a 3 bolt flange. ALSO it only works with the tsudo cause the tsudo uses USA specs pipe diameter, which is what all the inserts are made in. not in metric japan specs.
sorry bro...it won't work with the stock mid pipe.

your best bet would have to be the RESONATOR or to switch to a quieter axleback like Megan's OE styled or Tanabe's OE styled medallion, or greddy's sp2...etc...

 

WTF? Where do you get this idea that there are "two" spipes??

The only spipe/downpipe is after the header before the midpipe. There are only 4 pieces to our exhaust: header -> spipe -> midpipe -> axleback. There is nothing else.

 

You get all of them at once FOOL.

the TC's Down pipe is called and S pipe by some, why? you got me but when manufactures do it you can't argue to much.

on mid pipes like megan's tsudo's skunk2 etc...the mid pipe is made out of 2 pieces the front part is short straight pipe and the second is a n S shaped pipe known as an S-pipe...hmm...wanna get your foot out ya mouth there G...and my foot out cha A$$.
