GHL or Vibrant?

[Greysave]

haha how is it a catback? it kinda starts right after the s pipe, replaces 2 cats with one high flow, and replaces the resonator...and how would you work what he has for sale in with the vibrant? thatd be a hassle and way too much money spent.

The vibrant is far from a turbo back though, being as the Vibrant pipe never actually touches the turbo. I don't know why everyone complains about the ghl exhaust price, look at any good true turbo back exuast for an evo or sti, they are anywhere from 900 to 1500 depeneding.

far from it? yea like 6 inches. yea the stock s pipe may be small but the gains arent that different with an upgraded s pipe.

First, It doesn't matter how long the bottle neck is there is still an exhaust bottle neck there which will increase back pressure, bad for a turbo car. Second it looks to be a good foot and a half or so which is def longer then 6 inches. If what you were saying was true, then why do people get larger turbo housings? They are only a few inch long, but offer maximum top end horse power when going larger. The slower the air can get our of your exhaust the less power you will make. Physics is physics, and does not change for a speed, any exhaust choke point is bad on a turbo car.

the factory s pipe is not a foot long. i know exactly what youre saying but i couldnt justify spending an extra $400ish just for that small of a 'bottleneck'. yes the ghl is the best exhaust for the msp, but not by a whole lot.

I guess what I am saying is if you are a sports car enthesiust it would be warranted. First off down the line if you are trying to make more power it will be a necessity. Second, when you combine a lot of small hoarsepower increasing mods, they add up to one large hoarsepower increase. If you went through the trouble of getting an intake manifold and a exhaust manifold, why not go for the s pipe. What I have noticed about alot of people on msprotege is that, they aren't really going for performance, they are going for show/sound. If you are an advid performance enhiusist, you understand you have to pay to play. Every little bit counts, and another member has quoted that the s pipe alone gained about 15hp. The entire j pipe back section may only gain 15hp so this is huge for a small section of pipe. Furthermore this is the most inportant part of the exhaut, as this is where the exhuast initially gets expelled from the turbo thust not only effects hp,but also spool.

Amen.

I'm going through a whole process of basically having a 'custom' turboback exhaust built. I picked up a new Magnaflow 3" hi-flow cat tonight, along with a 2.5" s-pipe from Ben at HPF -- and then an exhaust shop around me is going to build the rest. I'll wind up with the 2.5" Corksport s-pipe, that expands immediately to a 3" j-pipe back -- with a single hi-flow cat and a 3" resonator, all of it made stainless. I can't wait!

For those that don't like any of the 'pre-built' options, there is always the choice of getting it all done by a local exhaust shop. Shrug.

well, i dont know anything about the vibrant but i like my ghl, if that helps any

Whoa, who said 15 hp from the s pipe upgrade? Is that supposed to be from the GHL s pipe because from what I have read the Corksport which is 2.4" is only good for around 7 horses. Oh and for all that want to know what I decided, I went with the Vibrant and will probably get the s pipe from Corksport. Thanks everyone for all your help!

15 hp? youll never see a dyno chart for that. im not a sound/show guy but i am most definitely not cutting corners here. like i said, i dont believe there is enough of a difference between the two exhausts to warrant spending that extra $400 or so.

 

[terbow]

i still have my reservations about the split pipe design downpipe. i personally feel a single large downpipe is far superior to a split one. I dont think the wastegate causes enough turbulence to justify splitting the exhaust paths. everyone knows how much turbos hate backpressure and at high hp (275+) i think the split design would rob you of hp over a single, large downpipe.

however, anything is better than stock so theres no need to split hairs.

We will see then. I have a j pipe back exhaust on now. I have a ghl waiting to be installed, if i can get my wastegate issues corrected then I may be willing to dyno to see the difference.

 

[terbow]

what kinda of j pipe back exhaust do you have? is it 3" from the j back? most likely not cause 3" wont attach to the j. so any dyno testing wouldnt really be conclusive unless you had 2 identical systems with a stock s and a non stock s. but dynoying is fun anyhow. and if u have a resonator on the ghl its really small so your bottleneck is still going to be tehre, just on teh other end . just a fyi

but again, anything is better than stock. ive had stock, ghl, vibrant and corksport. and all of them, while different help tremendously. the turbo literally chokes on the stock midpipe and j. the s isnt so bad cause the turbo spools fine, theres just more HP to be had with a bigger S (how much i coudlnt say as more boost or larger turbos would yield larger gains)

sweet, good luck on the install. what kinda issues? did it die on you? i cant wait to get back home and install my atp wga.

dude your car and mine get more and more alike everyday, wanna paint it silver

 

[Pyr0TeK]

3" GHL Stainless Turboback is the best exhaust for our car... HANDS DOWN ( yes I have one, best mod ever!). Also, it is the only true turboback exhaust. No other manufacturer has a true turboback. Also the GHL comes with a lifetime warranty. FTW!

naa you should paint yours black. i wanted to take my spoiler off but i had a friend photoshop it off and i realized wingless on with an 03 rear lip doesnt look good. yours looks great on the other hand bc you have the 03.5 of course. do you have some sort of ems for your car??

it is being worked on as we speak, a plug and play megasquirt system. full standalone

plug n play full standalone? wow didnt know the megasquirt was pnp. i met yellerandahalf at an autox and he seemed to have a really nice setup with the megasquirt, his car ran great. he also said he had free access to a dyno so that always helps. ive got an mpi on the way.

yeah i bought his MS, it isn't available as a PNP, but that is all about to change hopefully. Another member and I are in cohoots to put this out there as a viable option. Full standalone that is PNP and extremely affordable. He is an electrical engineer and I am just the test bed and the money. He has done a bit of work with MS though and we should be up and running pretty soon. I would like to have it on before my dyno on the 18th, I guess we'll see. If not a plan on pulling one with silencer, one without and then one with the dump pipe open to see if there is any changes. If the MS is in the car then i will try a couple different maps, Matt sent me his maps so I should be able to run a couple of them and do some fine tuning for my car.

A pnp Standalone would be nice! I am not a big fan of splicing wires, plus i've heard good stuff about M.S...How much would it cost?
