The OBX header with one-ball exhaust is economical so it draws people who aren't willing to dump thousands into the car. But will this exhaust combination work with higher hp applications? I'm specifically thinking +200whp. I don't think I've ever seen anyone doing this.

Looking at doing things economically. It'll cost money but there's no reason to be frivolous about it.

EDIT: OBX or Megan racing header. Didn't realize there were multiple options in the $200-300 range.

 

200hp's not cheap. So I think the one-ball and obx are a good way to start and leave yourself with some money to play with.

I did the one-ball with a good mendral bent elbow and it gave a noticable power increase.

The obx doesn't include a cat so I'm sure the header alone want limit to under 200hp but fitting the stock cat to it might be a bottlekneck.

 

I plan on fitting the stock cat to either the OBX or Megan header. From what I've read the stockie is a decent piece, but will it bottleneck things?

 

I think it is more complicated than saying that the stock cat can't flow 200hp. I thnk the right combination of mods and tuning could easily push 200hp through the stock cat, but everything else the same I think there is some power in the top end to be had from a racing cat.

Personally I am at ~190 (gtech measured and adjusted for actual stock) with: CAI, 19%, DFIC, MTH, One-ball. I just got a Milltek exhaust from Helix but I don't expect much of a power increase (over the one-ball).

I think to safely get over 200hp I'll go cam, header (w/ hi-flow cat), injectors and re-tune

 

What car weight do you have registered in your Gtech?

 

200 hp is big bucks I think it is pretty easy to get to the 170 -190 range over that $$$$$. I figured to get to 180 was about $7o per hp I paid to have the mods installed so if you can do it yourself it would be cheaper.

 

I think an important note here is that in your search for HP if the Header/1-ball are deemed to be holding you back the "change cost" will be small. Most likely you would leave the header and change out the 1-ball for a Catback.

I started w/ this exact set-up and loved it. I did go the more expensive route and purchased the www.myminiparts.com 1-ball parts but got my monies worth and when I swapped out I sold it and recouped a fair portion of my $$ lay out.

The reason I swapped out of the 1-ball was the desire for more sound and sexy tips. I can't say i gained any SOP performance going to the Catback.

You might want to look at the OBX Catback for 299.00 - lowest Catback entry point. Rather than repeat, search threads for OBX Catback or drop me a PM.

PS - OBX Header - very happy, no issues and no I would never remove it.

 

I have the OBX Header+aftermarket cat+one-ball and its a great combo. I have 204 at the wheels, and I'm not sure how much that number would change if I were to change to a "real" cat-back exhaust...probably not much at all.

 

I have an OBX and ONE ball with original cat installed.
Now I am planing to get out the cat and put the O2 simulator.

I think that is the cheapest exhaust and it is as good as others.

Catback probably do not give much power. A horse maybe two, so this is not worth the money (if you don't have it much).

Off course If I have all things which I want on the car, then I will be buy SUPERSPRINT system. But just for my inside feeling not for the power.
But now, the other mods have a priority.

Bye

 

I would agree - minimal gains. The catback decision is more on sound and sexy tips than anything else.

 

If you didn't know OBX is a SS knock-off.

 

I have known for the header, not for the cat back.

Thanks for the info, but the supersprint is supersprint. Like I am said-it's for my soul.

 

I hear ya - while I got the OBX header & catback on - I have authentic SS Viper tips sticking out the back. AND they look GREAT

 

I have 2850 entered but I've been just been using the Gtech to measure the change in horse power since stock, not relying on it to be accurate at calculating the actual value.

 

This is the point I was trying to make. There is a huge price gap between the OBX / Megan and others. I think the $600-$1000 difference could be spent somewhere else and do more to get you to 200hp.

I think custom tuning may be required to get my car in the 200's, I'm just trying to decide if it is worth it now or if I should wait till I can do the rest of the mods I want.

 

A TRUE custom tune will cost $$ so I would do it once your mods are completed. Interim basis you could go for a shelf tune, I did the GIAC and was pleased with the results for the $$. MTH might give you a little more flexibity but along the way but at the end of the day it too is off the shelf tune.

PS - By custom I mean that the tune is developed from data produced from YOUR car.
