I do not think this would work on a resonated test pipe. You would need a straight, non-resonated pipe.

I think it's 4", but I have the engineering schematic on my other computer. I can verify for you on Monday.

Intake package? Do you mean throttle body? If so, please PM Aby. If I am not understanding you correctly, pm me :)

This... {thumbup} :beer:

I beg to differ for now ....but I will check and see for other peoples opinions

below is a pic of my AMS Resonated testipe. I want to weld in the 100 cell cat onto the longer side of the piping on the test pipe....in the section right before it empties into the catback...

Actually, it looks like it would totally work. I have never seen a resonated test pipe like that before :D

I stand corrected. Please accept my humble apologies and buy one of my cats ;)

:lol: no problem man.... I was looking at my resonated TP today and saw that theres plenty of room back there to weld in a 4"-5" long 100 cell cat.....
I'll just have to go to a reputable shop that can weld it in properly and neatly.....

clearance should not be an issue either as the "resonator" is actually the widest point of the entire "Test-Pipe" unit...

so this way, I win 3 ways by gaining:

1) a quieter exhaust note
2) by being "green" not having to deal with the "no cat" smell
3) will flow almost like a test-pipe.

so with that being said and done I'd like to see what the flow and power differences are in full test-pipe vs. 100 cell cat

if the difference is 1-2 horsepower, I'd be willing to do this...

Before I plunk down my hard earned money, let me check with my muffler guy if he'd be willing to do this for me.

PM Aby. He will help you out. :)

Done... {thumbup}

Just wanted to give my opinion on these cats. I've run nearly all the HFCs out there on either my car or customer cars. Ever since MIL.SPEC and I have been working together I have been using these cats with outstanding results. They are truly the highest flowing cat on the market along with one of the lighest, which is an important factory for us racers.

Great products, great guys!!!! What else can you ask for?

I wanna ask for a free shipping :lol:

The bare cat weighs less than 2 pounds. We're already giving you guys Priority Mail included in the bare cat price :D

E-mail sent to Aby on hotside porting. {thumbup}

If Aby can make Indy cars faster, I am positive he can make yours faster as well {thumbup}

Check out these picks of our TB's for sale:

We also offer an intake manifold w/ porting exchange program. Installs can also be done locally if you're in SoCal. PM Aby for all the delicious details.

I would like to put in my 2 cents. I am no more than a third pary and am here to state facts.

Last night I tuned a FPGreen on Cosworth cams. It did end up picking up over 25 whp after the install of the TB. I will be posting the Dyno plots when time permits.

I would say at that point that would be considered a small Muffler and not a resonator. haha
