Cat or muffler removal?

[attackdog]

Hi all. I am thinking of removing the cat or muffler, or possibly both from the SY to get a little more sound/flow. I have a 20g14cm ported turbo with an ATR 3" stainless exhaust. Any suggestions would be helpfull. All my mods are in my sig. What would the pros and cons be with removal of one or the other or possibly both? Thanks.

When I bought my 92' Ty it did not have a catylitic converter, but it had the usual bolt-on's, the truck never over-boosted. I actually installed a high-flow cat, but it never spooled the same. I took it off and threw on a straight-pipe, now it runs as strong as before.

Did you still leave the muffler on without the cat or are you running without the cat and muffler? Thanks again.

With the 20g you can run and open down pipe if you would like.

But if you do not like loud exhaust then run no cat with a muffler.

That is what I am looking for. I am hoping to get more turbo sound also by just removing the cat. Thanks.

I guess I am looking for more turbo sound. My buddy just picked up a GN and has a T-44 with no cat and the turbo sounds awesome. I am going to try going with no cat and keep the muffler. Thanks for everyones input. Keep the ideas and suggestions coming.

If you want more turbo noise, I think shortening the span of the intake tube will work best....? I ran mine without a filter for a quick spin down the street and it sounded awesome...(not recomended I know) but it was a beautiful whistle!!!

gutted the cat today.what a difference ! befor boost set at 14-15,after guttin ,instant 18 with some knock.backed the boost down to 15,lost the knock. I LIKE IT . spools so much faster and holds it steadier.the added rumble with the borla and spool noise is a bonus.

If you want to hear the turbo more,run your inlet to the turbo to the front of the grill (or somewhere in front) of your vehicle w/a filter.

Re: Cat or muffler removal?

Here you can listen to these if you want. These were with a Kenny/Bell cat back no muffler. I now have a RPM cat back exhaust on it with muffler, but to be honest with you I miss the sound of no muffler.
