my exhaust is pretty much stock expect for the mufflers (magnaflow)
i think i'm going to change the midpipe to 3 inch H but just want to know what brand of catted h's will sound/perform best with the mufflers.

............don't rub it in:sorry i would but my parents won't let me do that till i'm 18.. that and where i live in Irvine the cops are extremely anal about the smallest of things and like if they even sense somthing is illegal they will pull u over..

so till im 18 i have to stick with catted.
any suggestions with a catted H

Yes, might be a little off topic at this point in the thread but, all the catted h pipes (for stock headers) made for 96-98 have been discontinued. I was the guy who posted a thread about this a week or so ago, then i did alot of research and found out that this was true. I personally like the deep muscle car sound so i decided to go longtubes and get a catted h pipe for those.

Sorry, forgot to add this. An x pipe is better flowing than an h pipe but not enough to cause a big fuss about. You arent going to pick up 10 extra horsepower going x rather than h.

H pipes are usually more of a deep muscle car tone and x pipes are more of an exotic or raspier tone.

np about goin off topic

ya i like the deep mucle tone but it seems that the only way to get that is too make custom H or Go O/R. so i'm pretty much stuck.

but i've been lookin at some vids and like theres only like a slight difference between a H-pipe and and X-pipe i mean at idle it sounds pretty much the same just when u get in the high Rpms.
 
#26 ·
Yes idle is pretty much similar but when you start to rev or get into the high rpms it starts to make more of a tinging noise or a pop when you let off the gas. I was thinking about going custom h for a while but then i realized i would rather have professionally done products on my car and it would probably sound better.

I was looking into slp catted x's for a while but then when i heard a setup with longtubes, catted h pipe, and flowmasters, i fell in love.

hmmmm your setup that u love gave me an idea
dunno if its california legal tho so tell me if it isn't.
but what if i went with bbk LT and The BBK Catted Short H-pipeBBK: 1979-2004 Mustang Exhaust H Mid Pipe With Converters like these ones.
but i like just worried bout the lt cause i heard that there not legal in cali or somthin
 
#29 ·
damn sounds so good

i wonder what it would sound like if i got the bbk lt h-pipe with my magnaflow mufflers.
 
#34 ·
ya i checked it and it says for the magnaflow true x that its 50 state legal same with the bbk so i'm good :D so i might go with those seeing that they discontinued the catted H.
