Im looking to convert my 98 V6 to dual exhaust..old exhuast rusting so gives me a good opportunity..wanted to know if there was a huge dif. in a catted x-pipe to a none catted? performance wise..Also if anyone has done this before what is the easiest way/cheapest way to do this. Im doing the instal myself with a few buddies in the college parking lot so im hoping its just a bolt up. Thanks

you would loose HP and torque with a non catted h-pipe. If you get a complete exhaust kit it may bolt up, but there may be some welding.

I would say, you should go with a kit... or you could get a custom one made... it will most likely require some welding... but a full kit should cost around $450 with duel flowmasters

As for H-X pipes can i use the 4.6/5.0 pipes cause ive only found one site that sells them specifically for V6's.

There are several, but the only x-pipe that really works better than the PAcesetter adapter is a Dr. Gas X-pipe.

If you can get it on a lift, it's a bolt on job. If you get side exhaust, you won't even need much of a lift,

Over the axle, rear pipes, you have to get the car so the axle is fully suspended, and you can slip the pipes over the axle, other wis you'll have to do some welding.

The cats aren't a resriction. The bigger danger is too much flow moving the powerband out of the range of the cam.

Go too big on the pipes, and you'll kill your hp / tq.

you need 2" -2.25" unless you're going to boost it with SC, Turbo, or N2O.

they're available in those sizes, or you can have the 2.5" GT system fitted with removeable reducers.

Where can i get the X-pipe then and i really dont see many cat back systems or X-pipes that are 2.25 or 2" unless i use a take-off. Which i would really be my last option.

Pypes, Spintech, Ford Racing, and Magnaflow have teh pipes, there may be others . . . I think MAC also has them.

The X-pipes are only available at Spintech, but it's expensive.

It's the only one that sells Dr. Gas.

But it's not much better than the Pacesetter h-pipe copnversion.

The uncatted off-road complete pypes x-pipe is $450
O2 sensor simulators are $55 for a pair

The catted version is $550 - so you would save $45 by getting the uncatted version & also the O2 sims. Free shipping helps :laughlitt


I as well am looking to eventually get one of the two systems...

Does anyone know if there is a significant difference in getting the uncatted w/o2 sims Vs. the catted x-pipes? - Besides the legal probs if your mechanic looks under the car while inspecting...

There is no difference.

you can get a catted x-pipe at spintech for 100 cheaper, and it's a Dr. Gas x-pipe.

go to www.gtrhipo.com

It's actually gone down a bit, it's $399 for the catted x-pipe!

yeah but i hate the way the the tail pipes on that kit look. Im looking for the good ol 3" stainless tips...i was planning on the off-road X-pipe from RPMoutlet.com-$159......then the MAC 2.5"Cat Back system from lmperformance.com-$284 I suppose that with free shipping the pipes system is probably cheaper but i guess i could cut the tail pipes off and put stainless tips on.
