X Pipe or H Pipe

The H is a waist of time & money

Very little gain, the "X" is by far better, especially with headers.... :bglasses:

 

X works better. H sounds better: H is a deeper tone versus UPS-truck-like for the X.

 

Not H or X pipe!

I have heard the J or L pipe is the best.
:Brow:

 

hey dont me knocking single exhaust. i still have it on my 350.

 

This is the latest in exhaust tech


"O" Pipe
You've heard of the Y pipe.. the X pipe.. the H pipe.. nothing can touch the O pipe!!! It provides 100% backpressure feedback on ALL engines!! Torque increase and kuneutson valve float brings in much lower revs so you don't hurt your motor! Pipe shown is powdercoat black for car with DUAL EXHAUST. Not CARB Legal. Please specify Stainless or Powdercoat and also if you are using dual or single exhaust. 3" diameter. ou: ou:

 

There really are so many this site here has some of the best performance parts and prices.

The OH ...(O) Pipe ?

I like the design of that O pipe. I bet it has no exhaust emissions whatsoever. Where can I get one or are they still in the testing
and prototype stage? Does it create 5 more horspower
at 9,000 rpm's than the H,X,Y,J or L pipe? o No:

 

What do you run at 9000 rpm? a Buick?

 

X-Pipe. However, I would caution against an X-pipe w/o any drive shaft loop... unless you just granny it everywhere. That being the case... there's no point in the X-pipe.

 

I have run the H-pipe... 'bout 30 years ago.... but at velocity I s'pose the X-pipe is the better unit.
