Anyone have JP V6 headers and cat back? - Toyota Nation Forum : Toyota Car and Truck Forums

Is it much louder than stock exhaust? I have the TRD SC and have ordered the headers. I don't want it very loud. I am building a steathly car.

The cat back from JP is a nice 3" unit, but their price is high. I can get a local exhaust guy to bend up a system. The local guy can make it as quiet as I like.

thanks

The JP has no cat? that's interesting.

Hypothetically......how would you lower the sound of the exhaust? if you had headers and say.....2.5" piping

I heard one idle but the idiot said he couldn't rev it up for some reason..
At idle it was quiet.

A big muffler with lots of bafles..?

i had jp put a flange on so i can run a test pipe. Sure, putting a couple huge resonators in your cat back piping will quet it down a lot.

Looks like I will go with the local guy for the cat back. Makes no sense to buy JP and then have to cut it up to make it quieter.

TRD4LIFE, you still got springs and a 6lb pulley for sale? I need some fuel enrichment also. Tuner tells me the stock pump is going out. It is running lean in the midrange.

I have no suspension springs for sale. I do have a URD Supergrip 6lb pulley although i think i am going to keep it for now. Contact thakidd i think he still has one for sale.

How much of an increase in performance did you get from the headers/y pipe/exhaust on a stock 1mz? Worth the money? Im doing a 5 speed swap right now and after that im most likely done on this car but i think some bolt on's would be fun...

dr, you gotta put up some pix when you finally get everythign going! I can't wait to see it.

The jp headers provide a 30whp increase when supercharged. N/A you might get 10whp, IMO not worth the money unless your blown. I would just do a custom y pipe and be doen with it.

Can any of you supercharged guys direct me where to find a supercharger? That was my original intent i just havent been able to find one in the last 7 months. 1mz supercharger =

. I gave up on a turbo because of funds, a supercharger would be bad ass!!!

They're out there but you'd have a bit of trouble fitting it to your Gen 3, someone did it. search for it.. or I can find it later.. I have to go to work now...

I had JP flange the cat also so I can test pipe it, at the track only of course :-)
I may post pics later, but it is nothing to look at. It is a grandma grocery getter. Gray, stock aluminum 15 in wheels. I am going to keep it that way. I am even pulling off the V6 tag. I will be getting some stickier tires on the stock wheels. I also may get some sticcer springs, but I really dont want to lower it very much, so I may skip that. It's all under the hood for me. As a joke I would like to put the smack down on my boss, who has a 02 911 vert that runs lows 13's if he can drive it that well. It was no fun to be him in my C6, as it was too easy. Beating him in a camry, now thats would be funny.
