Shoot Carl, I just yesterday put on an X-pipe with high flow cats. I didn't like the tone with my RMB, so I put my stock muffler back on. These may be what the Dr. ordered....

How would you rate the noise compared to the stock 88+ pipes with intermediate mufflers....is your setup louder or about the same?

Carl Fausett

It will be a litlle louder, with a deep, throaty pulsing sound. I plan on making an audio file of it as soon as I can.

Most folks with installed X's are of the same opinion...........there must be many RMB's sitting on garage floors.

I'd like to enjoy the look and lightness of my RMB again without the 'noise' and these mid mufflers may be the trick.

Ed Hughes and his 1991 (his post is just a little North of here ^ ) is getting a set and he is going to make us all a .wav file to listen to.

Carl are you going to make a 2.5" intermediate set also in the future?

Chuck Schreiber

Carl,

Any possibilities in the future for a 2 pipe down one side for the early model cars?? That way, we could add the X vs the Y in the future.

Hmm..niiiyyyce...I'm thinking Lomas X pipe...Car's intermediates and an 86.5 final for me....That'll work, right?

I know Stebro...I looked into their products for my Alfa 164, and they are well-known for their SVX exhausts...However, for that price...do I see non-mandrel bends at the first bend? Off to read the rest...

Any updates??

Here are some photos form the completed '85 install.

There are two projects going on at the same time here: I have developed a SS Intermediate exhaust for the 87-95 cars, and then secondly, I am trying to develop a kit for the 85-86 cars so they can upgrade to the late-model exhaust.
Photo beleow shows we are supplying all the hardware, ahngers, and even the RS heat shiel that the 85-86 cars are missing as part of our kit.

I hope to take this '85 to the dyno in the next 10 days or so - but the customer is still having us change springs and other things and the car ois not quite ready to drive down to Madison yet. Soon.

There are some very real restrictions in the 85-86 "dual" exhaust - I do expect a pretty good HP jump when its all said and done.

PS: the photos show this customer slected the mild steel RMB - that could just as easily be the Stainless Steel version. No problem.

Carl,

Nice job there!

Stainless Steel option and then polished tips at the end would be fantastic. I think you'll have a winner there. You've got a group of 78-86 owners that are craving this system! I would imagine a 79 would accept it with 85-86 manifolds, spacer, and x pipe upstream?

What is different in '95 MY? AFAIK all GTS have exact same exhaust if non cat Middle East version is not counted.

In any case looks good upgrade for stock engines.

Nice true dual exhaust option, should help with
