hi guys, im going to take out my secondary cat tomorow and make it straight. i have taken out my resonator and put x pipe ti replace it.. i know someone who had taken the secondary cat on top of the resonator just yest and they say the sound is crazy.. so ill be posting if i got the chance.. anyone done it before?

I've done it with the x pipe and had secondary kleemann cats installed, its brutal with the Kleemann headers right now. Sounds like a mini SLR and the cold start is just spine tingling.

A video o audio file to hear the small SLR ????

Yep, a full exhaust setup does sound great!

If you have it done, do post a clip. I'd be interested in getting it done, but to drop it from the collector back to properly TIG the pipes would be costly for just removing the 2nd set of CAT's. On the '06's they moved the 2nd cat past the bend, to the center of the car, some 5-6" in front of where the resonator sits. Not a lot of room.

My setup is

Kleemann long tube headers > Kleemann downpipes > Kleemann 3" 200 cell racing cats > SuperSprint/Carlsson X pipe > AMG mufflers

Long tubes are a whole different game from just 2nd CAT removal. I had them on my old Roush, no CATS, and two race cans. My neighbors hated me in the mornings.

Its the best alarm for the neighbors,

barnabas

Has anyone thought of using "short tube" headers? Vadim at VRP has a set and Omey at Aberdin is soon to come out with a slightly different design (recent hurricane in TX has set him back a bit, unfortunately). I am evaluating each before buying a set.

I have a full exhaust (catless & x-pipe) with AMG stock mufflers, and my wife hates it when I start it up every morning.

A'LAF1,
You will want to stick with stainless tubing and good welds, otherwise you will have to service them like I change my engine oil at every 1500 miles. If I remember correctly, I don't think VRP's manifolds are made out of stainless but coated steel, I could be wrong though.

A' La F1

Thanks, 2manycars. Correct, VRP's are ceramic coated mild steel whilst Abedin's are stainless steel, mandrel bent merged collectors with TIG welds. I am waiting for Abedin to get his operations up and running after the hurricane so that I can inspect the product first hand. I visited Vadim a couple months ago and he is pretty well versed in Merc and Merc tuning, but he didn't have any headers for me to look at. I believe he has some now.

Here is a prototype of the AMS (Abedin) shorty header.

2MANYCARS

Wow, Abedin headers look well made, I'm sure they will do wonders for you.

i got mine done just this morning and I love the sound.. its prob like 40% more than replaced resonator.. the low grunt is much heavier and louder and when u pedal the car, the rattle is very obvious.. i dont have any webcam or anything but ill try to post it if i can

lsufan

Sweet. Did you have the pipes TIG welded? How much did it run you? 40% more grunt volume than just resonator...now I got to do it. Thanks, it's going to cost at least two pair of Aldo's with the wife.

barnabas

lol... whats TIG? i have no idea.. yea u gonna love the sound.. low or high revs its very nice

TIG is a high end method in welding, TIG welding is what people usually call it, crack and maintenece free if the welder knows what he is doing. Other shops such as Midas uses MIG, as it's a cheaper method to weld and not as durable as TIG's finish.

Tungsten Inert Gas (TIG) vs. Metal Inert Gas (MIG).
