Dump Pipe Wont Make A Difference?

[DaGr81]

I changed my dump and front pipes together left the cat stock , felt tonnes better back in the day it sounds nicer and you can feel the difference, 20rwkw difference then I changed my cat later and scored 5 more!

If your doubting what everyones saying just give us the keys to your car and $1000 we'll modify it for you not some backyard mechanic. (better us than a mechanic like that)

1000 =

Stainless dump and front pipes + cat fitted

Food for us all

Petrol

Maybe a cheap set of rear rubbers to prove the difference ^_^

Anyone wanna modify it for him?

SIGNIFICANT

do the front pipe too.

So far 9 out of 10 people say fitting a dump pipe will give gains BUT.... i noticed that along with changing the dump,most ppl also changed the cat,front pipe or the complete exhaust at the same time.

I already have a 3" cat-less exhaust from the stock dump pipe back.What kind of gains will i experience if i go with a bell mouth dump? Also all these dump pipes u guys are referring to are 3" right?

considering you dont have a cat the dump/front is the last restriction in your exhaust!

purchase a JJR Bellmouth, as i did, and be happy!

jeez, re-read mr.

its been stated that a 3" jjr bellmouth dump pipe (turbo to cat) will net a easy/lazy 20kw plus

I cant see how this thread needed 3 pages

Just thought i'd throw this in.....

When i originally put the 25det (tranny) in my C35 it had only the stock dump and front pipe. I drove it 2 days like this and then fitted a 3" exhaust from the stock dump with a resonator and barrel, no cat.

With nothing else being done, it pulled considerably better in the midrange with the exhaust fitted, as before it was just feeling flat.

Alot of ppl here mentioned turbos don't like restriction .....so how come after fitting an exhaust with a resonator my car felt better?!?

Probably only persons who have done conversions might be able to comment?

I mean..... how many skyline owners drive around with no exhaust
