Hi all,

I'm just wondering if I could only delete the second resonator on my 968, make it straight to a universal after market muffler?

I know I wont gain any HP and it's not the goal, I just want a deeper and more "agressive" sound.

If it's doable, let me know which universal muffler I should get to have a deeper sound.

thanks

Really, no body have a opinion or comment on that?

I replaced the back muffler with a straight through. The two exhaust pipes were cut and replaced with a Y pipe. At first I had it without a muffler and it was too loud. So I added the straight though muffler and it sounds better. much deeper and louder.
There is minimal drone at 2,800 rpm at speed. Loss some weight back there and got better response at the low end. Seems to loss a little at the top end.

I'm happy with it. May want ot try a bigger Diameter Y pipe/ straight through though.

Oh, there is a vendor that sell a cat back......heard good things about it.
Don't know if I can name the vendor on this forum. Luck

What brand of muffler did you use?

And does somebody have the specs of the universal muffler I should buy?
I would like to buy all my stuff before going to a exhaust shop.

thanks again...

You might want to look at the options that RS Barn offers, I know they have a few different exhaust packages.

I was just about to mention that i was going to purchase the RS Barn catback pretty soon. Although Im very happy with just the headers and the stock cat back...

I have the RS Barns Cat back and is very happy with the sound. I do not think it's adds any HP, but sounds nice

B&B also makes a CAT back. Others have changed the muffler to get the desired effect. In the end, none of these system are worth much in performance.

Very true. I've been told some even lose power...

Update,
The rear muffler is a round stright through.... I kept the resonanter. I can hear the exhaust more than tire/road noise which is what I prefer and I loss weight in the back.

So I can mention RS Barn. I understand you do gain so Hp with their setup.

It is good ettiquette not to mention banned vendors.

I recall a post by Odurandina on this forum a few months ago. He replaced the enitre cat back with an aftermarket resonator and muffler. He liked the result and saved a lot of weight and cash. He had specific manufature/model numbrs in his post, He brought his parts to a muffler shop and had it welded up. He is easy to find on this forum and will be glad to give the info you are looking for.

Is RS Barn banned? If so, why?
