Need help deciding..
2000 Pontiac T/A
Already purchased Pacesetter LT headers but which pipe setup do you guys recommend? Is there a difference with back pressure and/or sound? Has anyone used either setup with Pacesetter headers?

Thanks,
Jim

 

I've had both.. Got rid of them and went with a custom y

Ground clearnce sucked with TDs

X= high pitched, exotic nascar type sound

H= deep, bassy old muscle car sound

 

Yup, this has been plaguing mustang guys for quite a while. I went with the X when I used to have my mustang, although rasp doesn't bother me.

 

Are you definitely going with true duals? If not, the custom y (Flowmaster merge) option would certainly work well going to a nice catback. I guess I'm a bit partial as a "Y" guy.

I've tried so hard to look past the desire for true duals for a while. Every time I feel like I want to pull the trigger I realize how tough it is already with the y-pipe setup when it comes to ground clearance and I simply can't sacrafice anymore.

 

on my mustang I had a Bassani ORX, then when with a BBK ORH

 

As far as horsepower goes, your probably not going to be able to tell a difference with either an "X" or an "H". As far as sound goes, it seems a lot of people with true duals like the sound of an "H" pipe. Plus, everyone and their mother-in-law goes with an "X" pipe set up, so you could be different and go with an "H". Either way, it's going to sound great.

 

X or go home!

 

X-pipe for maximum power.....

 

Go h-pipe all the way. I have an h in my tru duals. I couldn't be happier in how it sounds my car is on stock cam and I have had several H/C LS guys comment on how good my car sounds I had to do something right.

 

Custom 3" true duals X pipe with moroso spiral flows vid is in the sig. This setup sounds nasty. I built it so the x fits in the center of the drop down for a umi chassis mount torque arm.

 

H has more low end tq

X has more top end hp

 

Actually most of the boom tubes are "H-pipes".

 

You should know what I'm talking about after I made a bajillion TD threads

 

I should know because I have done all 3 as well. Plus, you did make a thread or 12 back in the day!

 

Did you feel any difference between the X and H pipe setups? From looking at dyno graphs the gains that one might have over the other seem so marginal that I can't help but call out someone who's 100% set on an X pipe "becaus it makes max power" and say they've fallen into the hype.

 

I think they sound and perform about the same on a H/C/I car. To me, personally, it just came down to what was easier to fab up and what had the best clearance.

 

I did..

When I had the X, I lost low end tq, but gained it on the top end

when I had my H, my low end tq was back big time. And didn't pull as hard up top


Go with a Prochamber.. Best of both worlds.. Its an X and H lol

 

I'm going to try not to hijack this thread, but here is what I'm building:





That's a 3" flowmaster D port merge. It should work a lot like an H and an X, I hope. I've got more info on it in my sig link.

I'll let everyone know how it works out when I get it all fabbed up. FWIW, it's the same pipe kit that JMM98LS1 uses, only I'm using Warlock mufflers instead of 1 chamber flowmasters.

 

I just went to an X with moroso spiral flows. Sounds a lot deeper than my Y setup. Also picked up a couple mph at the track. Only thing I hate is ground clearence sucks and its a lot louder at idle.
