I'm going to go with the CIA headers, and the Magnaflow universal cat conv and the 2.5" exhaust. I think the catback is a good compromise between Flowmaster and the Borla.

 

I am new the forum but I just bought a 1998 camaro with the 3.8 series II engine. The car is an automatic. I removed the cat and my torque, gas mileage, and everything improved. The SES light DID NOT come on. I have a question about what exhaust will sound the best. I have an idea about putting a flowmaster in the place of the cat and then running duels all the way back instead of putting the muffler under the rear of the car. Any ideas help. Thanks

 

I think you need to also consider upgrading the stock S-Pipe:

 

I went with the Borla, the advantage is the sound is adjustable with different restrictor plates on the passenger side between the flanges:



Last I checked, Autoanything.com had the best price, either wait for their 15% sale, or use a Bing Cashback discount...

 

Thanks to both of you. I have had several older cars and unlike the camaro the muffler is under the car before the rearend. I was just curious if i was to upgrade the s-pipe and put the muffler where the cat was would that take way some of the rasp. i know it will not sound like a v8 but i dont want it to sound like crap. thanks

 

What muffler would sound best if I did the setup with the muffler in the place of the cat and then dualed back?

 

FYI, with my RS' exhaust removed from the S-Pipe junction back, it doesn't sound all that bad, and with more bass... Never-the-less, I would not recommend it. ;-)

 

This may sound stupid but what exactly is the S-Pipe and where is it located. I use to have a 84 z28 so this newer stuff i know little about it. Thanks for the help too

Thanks I'm gonna try and run duals and a new S-pipe.
