Question about \'94 RT/10 exhaust.....

I am pretty new to the viper forum...... more used to the LSX platform, so my question how do u guys think about this exhaust set-up...... i will be pulling of the side-sills and removing the stock mufflers on either side, keeping the stock-cats... but now should I go with bullet style muffler or just go with straight pipes off the cats ? Are the mufflers bolt-ons to the cats or welded ? thanks guys !

Re: Question about \'94 RT/10 exhaust.....

Replace the cats with high-flow at the least, you get both gains and less interior heat. After that you can go straight pipes if you are into a mind numbing sound or get an aftermarket muffler (i'll let others chime in on type).

If you want to ditch something, at least ditch the cats. As mentioned above, they are the main source of interior heat.

I personally use no cats at all. My mufflers are Spintechs. It's loud and I like it. Got about 500$ down in the conversion, materials & labor included.

If things become too noisy to your liking, you could think about using high flow cats or even glasspacks.

Go with a high flow cat and Borla cat back (muffler) That's what I have. And yes they are welded but you can change that to clamps.

Get the Roe kit for Gen I. Added 22 RWHP to my 94. Easy to install.

Agreed. Resonable cost and easy to install.

Re: Question about \'94 RT/10 exhaust.....

I tried removing the stock cats and mufflers and replacing with just high flow cats. Way to loud.
Went with 18" round dual tube glasspack high performance mufflers from JC Whitney for $32.00 each. Sounds good and runs great.

For those of you who have the roe kit, how is the sound.I was thinking of purchasing the kit myself.

The roe kit sounds awesome. Phil's Viper sounds like a Viper should sound...my 2 cents.

Re: Question about \'94 RT/10 exhaust.....

The Roe kit sounds great, I'll never go back to the stock
exhaust.

Leave stock cat? You're replacing the wrong thing.

Re: Question about \'94 RT/10 exhaust.....

You might consider removing the cats and adding a resonator.
This will give a little more hp and reduce a lot of heat.
I'm using Borla mufflers, resonators with dynomax cones to reduce the noise. I found the noise to be a problem with a side exhaust car.

Re: Question about \'94 RT/10 exhaust.....

I agree with the no cats on a Gen1 car. You won't be able to tell the difference because the Gen1 engines burn so clean and the side sills will be way cooler. I had a borla muffler on mine. It was loud, but not unbearable until I installed headers.

Re: Question about \'94 RT/10 exhaust.....

Had the Sean Roe Gen1 kit on mine as well loved it...Even better when i took out the cats..

so your saying because "it burns clean" I could pass the sniffer test w/o cats ?!?

o btw what size piping should I get 3' right ? Im cutting right between the cats and the muffler.... and where the muffler was replacing it with straight pipes, and then cutting off the stock tips and clamping them to the new pipes...should be quite easy and VERY cost effective AND still pass smog

Re: Question about \'94 RT/10 exhaust.....

grkss400hp, Stop for a second. You are replacing the wrong thing. Cut out the stock cat. Replace with stainless 2.5" pipe. Make sure to keep everything in alignment and measure overall length before and after so everything lines up well afterwards. I actually tacked the exhaust to two tables, cut out the cat, welded in new piece. The exhaust never moved so it went perfectly back in. The nsee what you think. If need be, you can play around with different mufflers later but I'm sure you will be happy.

Re: Question about \'94 RT/10 exhaust.....

You're not gonna pass CA smog with out cats. Just buy Sean Roe's high flow exhaust package with high flow cats.

Re: Question about \'94 RT/10 exhaust.....

ok i decided after looking how close the stock muffler and cat are to each other, to cut them out as a whole....

so ill be cutting before the cat, and putting in 2.5 inch tubes($10.95 x 2)....and either a borla Xr-1 ($130 x 2) or a dynomax bullet ($33 x 2) and using 4 dynomax band clamps(8.95x4) to hold it all together....

in theory it will sound good, guess ill find out

Re: Question about \'94 RT/10 exhaust.....

Might want to consider the Moroso Spiral Flow mufflers too...about $50 each:

well i literally just finished pulling the stock stuff off and to tell you the truth it doesnt sound too bad with open headers......so with that said im going to go ahead and clamp up the 4 foot pipe I bought and go from there if its too loud I have the dynomax bullet mufflers I can add....

i let ya know in about a day or two, when I have some time to finish this all up....
