2.25 Mandrel Midpipe

[ATRIOT]

Just put on my midpipe last night, everything about this mod has pretty much been covered already so i dont have that much more to add. The noise is great, it just deepens the stock sound and is perfect IMO. Hand tools might not cut it when your installing it, i had to heat up the bolts on the flange holding it on to the cat with a torch to get them off. Other than that the install is quick and easy. The only other problem i ran into was that i needed 2 new 15mm nuts and washers, because on the stock midpipe the nuts are welded on, and on my aftermarket pipe there were just 2 holes.

Looks: -n/a
Performance: - Unsure of the actual gains (mods on the K-series seem to be synergestic, being that they show results when only when used in conjunction with other improvments ie. Airflow in, Exhaust flow out.)
Value-10 (one of the cheapest mods you can do)
Sound-10 (it sounds how the EP3 should have sounded stock)

:cool:

is there a company that makes a mid pipe for our car or did you have it custom made?

[ATRIOT]

I bought mine used of another ephatch member (thanks Anthony ;) )I think there are a few companies who have them pre-made, MBRP in Canada (not sure of the spelling), and mabey muffler tech. Your best bet is to go to a local exhaust shop and get them to custom make you one with mandrel bends and new flanges. They might not be able to do the mandrel bends though so you might need to call up a few shops.

do u have a stok muffler on it
cuz i wuz gonna get on 2.25 done n have a muffler shop expand the inlet pipe to the same size supposably for better flow of exhuast. i dont know if any one has tried this yet but do u think it would work or should i jus invest into a muffler with a silencer. im tryin to keep it lookin simple with a lil drop n some rime. i dont wanna be heard at 30mph from 3 blocks away ya know

[ATRIOT]

I really dont thing that there's a need, the CTR's use the exact same muffler, they flow just as well as aftermarket ones, apparently their good for up to 200hp.

I glad you like your midpipe;)

BTW I forgot to give you the warranty invoice, you'll need it if you want Brullen's lifetime warranty. I hold on to it and put it with my records so if you ever wanna pick just let me know, I won't throw it away (You'll probably never need it but just letting you know).

Theres mandrel and crush bend. With Mandrel bend if your getting lets say your getting 2.25 inch piping its gonna be 2.25 throgh the whole pipe. Now when you crush it its not gonna be 2.25 because of the bend you have in the pipe. Know what I mean? Cause I dunno how to explain it any better. Maybe someone else can give it a try.

[oldschoolimport]

the best way to explain mandrel, take a drinking straw and make it bend around your finger. see how it flattens out? mandrel bending keeps the pipe from flattening out and losing size like the straw did. the mandrel is inserted inside the pipe before bending to help it keep its shape and therefore size and is removed after bending. that is a little over exaggerated, but you get the point.

[SilVic]

how can u estimate shipping costs? I don't know how to...

[chubbychu]

is it just me...or are there a lot of basic questions being asked here?

if u dont mind me askin what is a ctr

i find nothing wrong with these questions...except that, if you searched for a SECOND...you could have found it, but once again, i have nothing against asking simple questions...i just thought this was amusing, so i brought it up. lol!

Here's the explanation for mandrel bent vs crush bent.

Crush Bent:
(Like said above) As you bend the pipe, the inside diameter becomes smaller than the straight pieces. This makes for an inconsistant flow.

Mandrel Bent:
Instead of just bending the pipe, it's actually "stretched" so that the inside diameterof the bends stay the same size as the straights.


I have a 2.25 MB exhaust on my car and it's great!

well.. the inlet on the muffler is already like 2 and a quarter anyways. i just had my midpipe done, and i didnt even have to unbolt anything, we just cut it out between the flanges, so the cat outlet is still small, but the muffler inlet is pretty big to start, and face it, idk if mandrels even worth the extra few $ anymore. even with a crush bend, your still DOUBLING your flow capacity. i know the guy who owns a local shop so i got mine done for 50$

[03EP3Si]

Ok for Crush bent.. what if you use a 2.5 inch Crush bent pipe to compensate when the pipe becomes smaller around the bends? Do you think we would lose to much torque with that big of a pipe?

[rs_1101]

idk. i already feel low end torque loss with my pipe, but its just a butt dyno and itd be very very slight tq loss like 2-3 until you hit about 3500 rpm, then the cam gets out of synk till vtect kicks in. so right aroun 4500+ it sounds so perfect. thats when u can feel the gain, cuz i swear, my motor has never sounded happier at that rpm.

[03EP3Si]

Thanks bro! 2.25 it is! lataz

[rs_1101]

hahahaha... yea. dont rush off just yet, does anyone know if theres a sound quality difference between mandrel and crush? lol.. yea and dont forget to visit one of the resonator discussions... to res or not to res (i dont)

[03EP3Si]

hmmmmm.. i dont think ill need a resognator....i heard it makes a nice sounds without it.. and plus resognator.... just screws up the flow anyway.:D
