Cheapest way to eliminate the torque dip
 

I've been searching through the various threads on exhausts and have been pretty unimpressed with the results. To me, the gains are like those seen on motorcycles. So, is the stock stuff just that good?

What would be the most efficient/cheapest way to get rid of some of the torque dip? I am thinking Nameless front pipe with helmholtz resonators and high-flow cat + tune seems to be the best bang for buck. Maybe headers too...what do you think?

Don't really want more sound out of the car, just smoother power.

Yeah, I don't even have the car yet, but need something to occupy time.

Header seems to be the biggest gains and fix the torque dip based on the Nameless and P&L dynos

e85.

Not sure if its the cheapest, but the right headers and a tune seem to do the trick. Or if you have can get it, an E85 tune alone does pretty well with the dip.

No E85 where I am, but seems like headers beat front pipe by a good bit then?

After owning a WRX for many years and doing mods on the cheap (that end up more expensive), I think paying a few hundred more up front isn't going to be as hard to justify.

Any of the dynos showing headers use stock exhaust?

I've complained about borla quality because I got the dreaded warped flange syndrome, but honestly with the visconti tune and the Borla UEL, I cannot feel the torque dip any longer.

Header + full exhaust + tune.

Start with a tune.

honestly, if you want to get rid of the dip for realz.... equal length de catted header, high flow catted front / over pipe combo, axle back and a good tune.

I would not spend the money on multiple tunes and a good tune for an equal length header would not be the same tune as for stock manifold so if you want to do it in stages... axle back and front / over pipe, then header, then tune. Otherwise you will be paying for more than one tune.

Not sure how it works with other vendors but if you buy a tune from visconti you will not need to buy multiple tunes. Just buy the base tune, add parts, record data and send him the logs. He'll update for free. Just saying...

Since you are in MD, do you know if Jermaine at TurboXS is doing NA BRZ tuning? He tuned by WRX. I prefer to get a real dyno tune since there's several shops in my area that can do it.

This makes sense, I just don't want the extra noise, so planning on keeping the stock cat-back even at the expense of weight/power.

I've had enough years of full exhaust on my WRX to know what it will sound like on a daily commute.:bonk:

Cheapest way is to go turbo or supercharger bro. You're going to spend alot of money to *reduce* *some* of the torque dip. Save it for forced induction. I am going the supercharger route.

Borla UEL and Tune. :)

Where in VA are you?
