Im running a 2k3 auto w/ full suspension, greddy evo, frankencar intake. What should i get next? UDP or Cattman y-pipe?

 

since you already have the greddy, I dont see a point running stock and super restrictive ypipe with it. so I voted for ypipe.

 

I like both mods. The Y pipe gets my vote for great performance increase but the downside is your exhaust will be somewhat louder.

 

Y-pipe all tha way!!!

Both would be the best!

 

Y-Pipe is the way to go. The gains are there. It will be louder though, but since you already have the EVO, loud is probably not a huge issue.

 

anyone has a sound clip of greddy evo/ cattman y-pipe combo?

 

Look at Polo's site. He has a couple of clips.

Definitely get the y-pipe!

 

i must agree with everyone. the y-pipe is the way to go. i just got mine installed a few weeks ago, and the gains are incredible.

 

I'd say go for the y-pipe unless you want to avoid any more noise. UDP makes ya a bit quicker, and no noise is associated with it. But first choice, go for the y-pipe

 

Does the y-pipe make the car drones more? Im just afriad that the y pipe/ greddy evo/ frankencar combo will become too loud and attract cops.

 

yes and yes.....mine drones and it is only a 3.0 engine. It is loud too.

greddy evo with stock ypipe - nice deep rumble, no drone.

greddy evo with aftermarket ypipe - you will hate to stay in 2000 - 2500rpm....drone like a mother.

 

Y-pipe first..the UDP can wait..doesn't do a whole lot anyway

 

Here's a thread with some more detail of my noise impression with the Y. I also have a Greddy Evo and CM straight pipe.

It will make it a little louder but nothing that will attract cops. I had a GReddy Evo on my Eclipse and it was way louder than the EVO / test pipe / y-pipe on the Max.

 

Best way not to attract cops is not to speed....

 

Id listen to him...trust me, he'd know better then you'd think

 

Between these two, I'd say the Y-pipe will be next.
