what do u think the best exahust system is for the RA

 

The car is so new, there's really not a lot of options out there right now.

Right now, there's the RRM axle-back, and the Ultimate Racing cat-back. The RA has 2 1/8" exhaust from factory, so I'm not sure just how much more you're going to gain from an exhaust. Ultimate dynoed their exhaust/intake system and gained about 9-10 whp, so it's your call.

Most other manufacturers will probably drop their exhausts sometime late spring/summer. Then we'll see options.

 

oops, my bad.......Greddy sorta has one out too. Check it out here.

ooo nice.....so that evo exahust fits the ralliart?

 

yep, with minor modification outline in that post. I read somewhere else on here that depending on how much work they have to do, the official Greddy Ralliart exhaust will be out as soon as a few weeks, or Summer.

But literally everyone is getting ready to roll out products for us, so it will only be a matter of time before we have tons of options!

 

Looks good.
Got any video/sound clips?

 

Haven't heard any soundclips as of yet from anyone, but you might want to pm TurboTech P.R. and see if he's got any lying around. He dynos his car, so he may have recorded it.

To sum up, there are 5 choices right now when looking at RA exhaust.

1. RRM axle-back
2. Ultimate Racing Cat-Back
3. Custom Exhaust shop install
4. "Custom" Greddy exhaust (a-la TurboTech P.R.)
5. Stick with the stock exhaust! (That's what I'm doin... :spins: )

 

Yeah, the Ralliart already sounds pretty good stock (2 1/8 from the factory, of course )
So Ultimate Racings catback really gives 9-10 whp??

 

no, that's the dyno with the SRI and the Cat-back combined.

I think the restrictive factor here is the intake.....a bigger exhaust might do a little, but not much for our cars.
