Default Good exaust for a .28?

I've been running my RB 928 in my Jammin truggy this year. The pipe that I am running is the JP 2. Works well, but is there better? I'm thinking about getting a JP 4.

Anybody try any good pipes for a high RPM .28 bigblock?

Try the Tsias T-32 pipe/header. Really lets the big motors breathe. A-Main has the Hard Coat for like 65$ or so...

I personally have no idea but I can say Steve knows what he's talking about. When watching a race and you think to yourself "Hole crap that truck is fast!" It was probably Steve's.

i would say JP-3. the jp2 helps it with only top end and the jp-3 helps with low-mid to high. which is what you probably need

Yea,he is correct. The TISAS T-32 pipe set will make
that .28 scream. It's the best big-block pipe I've found.

Thanks Troy, glad somebody notices it!
I highly recomend NOT putting a JP-3 on a big motor. They choke down the .28's and don't help them at all. Trust me on this, the Tsais pipe is an awesome performer, pretty loud, but hey, you got a big motor, let everybody know!

The JP-2 works good, as it is a mid-top pipe. The Tsais pipe works even better, though. Dont get me wrong, the JP-3 is an excellent performer on .21's.

Once apon a time I did something stupid like put a JP1 on a RB 728. That choked it down big time. Right now I'm running a JP2 on my 928 and that thing is a missle!! No .21 can out run me!! I have way too much power. Not complaining.. The only problem that I am having is that It might be breathing way too good. It's sounds like I have open headers and the pipe is just there as a side note. I'm looking for something that will make the power more linier and controlable vs. Top fuel dragster ish!!
My other idea is to just drop in a .21 and be happy, but..... Damn I love to pull that trigger and watch my tires throw 4 rooster tails of dirt as I go down the straight!! My happy moment. Oh yes, I do win sometime too!

I will check out that Tsais pipe!! I am open to more ideas also!
