After almost a year of having a car I have finally decided to do some major upgrades.

I have the underdrive pulley and tie bar in route, and a set of 5Zigen GN+ wheels. I already have an SRI, underhood and in car bushings and short shifter.

The GF is going to spend $500 for my birthday so I'm having trouble deciding if I want the piggy back or something else. That is probibly the best performance choice for the money so I think I will stick with that. What do you guys think, should I get it now or something else?

 

I'd go with the piggy.

 

no point to go for the piggy yet...

his intake side is opened but exhaust side is still restricted...

do a complete exhaust system, downpipe, manifold...
then intake manifold port and polish...

then do the piggy back so you can adjust the fuel maps for extra flow

 

Well, I could purchase that myself, but wouldn't the piggy give the most gain for the price right out of the box or would it be nothing because of the exhaust side.

 

As far as power goes, the piggyback will give you the most gain. You don't need an exhaust to feel good gains. Most people with the piggyback have no more than an axleback muffler.

 

the biggest problem for RA on ehxast side is not at the axelback .....its around the downpipe...

if you put your RA up on the lift you will see the area around front axle were the exhaust basically goes down to 1" ,,,

yest there are some gains with a change of the muffler and elimination of the 2 90 degree bends...but the gains from the piggyback will be double when the whole exhaust is done properly with attention to flow.

 

youll be happy with a piggy and stock exhaust. the ralliart actually comes with a decent exhaust.

 

I'm aware of the problems with our exhaust, however, that doesn't mean you won't get very good gains with the piggyback. By pointing out that most people with the piggyback only have an axleback, my point was that you don't need to do any significant exhaust upgrades to feel big gains from the piggyback.

 

No point in going piggy yet? RRM has the papers to prove that with an axelback, piggy and CAI they saw a 27 hp gain. Now, this is just my guess but I'd wager at least 60% of that gain is the piggy alone. RPW saw what, 7whp (up top and a loss of 3whp down low) with a header. Granted, that was still on a stock airbox, *BUT* we are talking about most bang for your $500.00. Yes, the stock header/dp is restrictive. Had he said $1,000.00, I'd have suggested piggy/header.

 

Spending the extra money for a header isn't a big issue.

 

If you'd like to try an RA with the UDP, piggy, and CAI, I'm just down in Racine County. I still have the stock exhaust, and I'm quite happy with the piggy.

I've also got the tie bars, rear sway bar and perches, Progress springs, and shifter and underhood bushings.

 

If you could that would be better togather with the piggyback. Just like to know what is the stock diameter of the exhaust?

 

What about the RPW Haltech Interceptor setup

 

These posted results speak for themselves:

If you compare Blk-majik's 3 runs, his best HP was with CAI, Piggy, and Pulley (no exhaust). When he added catback with CAI and piggy, HP was virtually the same but he lost 3ft/lb tque.

Now if you look at the results posted by qlitv, and rickyMivec who both have intake, downpipe, exhaust, results are very similar - maybe slightly better HP, and slightly lower tque numbers.

I have yet to see results by someone with CAI, pulley, Piggyback, and downpipe. My guess - 171HP 169 ft/lb.

 

thanks for those numbers bud. good finds
