Exhaust b18c7 in ek1

[Hellomotog]

Hey guys what exhaust u recon I should put on my ek

It's a b18c7 in a ek1
I'm leaning towards a 2.25 with a twin loop muffler.

Mandrel or press bend?

[jajaja]

if ur on a budget go for custom. if not then buy a branded one that has proven gains. also if custom go mandrel bent cos press bent will restrict flow.

[FAITHLESS]

Mandrel is good. All you really want from the headers back is unrestricted flow. I would personally go 2.5" because it's never a bad thing to be a little too big if you know what I'm saying....

2.5" mandrel

[impossi13le]

i'd say go for 2.5" with high flow cat. 2.25" could be a little bit small for power gains/future power gains (turbo etc). Don't go with press bent systems unless you want less/no power gain than oem with your new system

Custom exhaust on my EG with B18c2, cost me around $1000. That was 2.5", mandrel bends and 2 resonators. I STRONGLY suggest you go for more than 1 resonator and get BIG ones to muffle out as much raspy as possible which is very common in multivalve 4 cylinders.

you can get a custom made mandrel bent mid pipe done in 2.5" at budget exhausts in condell park for about 350. buy a set of extractors and a muffler and you're all good. should be looking at roughly 1k more or less for a decent system.

unleash, why do a lot of people think xforce extractors are crap? I'm running a set on mine, they're very lightweight for what they are and have given me no issues whatsoever, no leaks cracks etc :S

[unl3a5h]

its not they give issues they are just not the best quality the welds are a bit rough and compared to a decent set of todas they are shitty. for the price they are a great buy and you cant really go wrong

[Hellomotog]

Ye I got a set of pacemakers. They need to be port matched so I'm gonna do that. Then probably a twin loop xforce exhaust.

So 350 s bends
250 pacemakers
And 250 for twin loop

850 total.

Did I miss anything ?

[Hellomotog]

Pace makers sound similar to the xforce.
But I guess if u port match and they don't leak they will be just as good
