Exhaust for 99-02 Silverado

KMT15 · March 19, 2002

Im new to the site. I am thinking of buying a flowmaster dual exhaust system for my truck. I have heard the 70 series is not very loud. I want it to be loud but not sound like a sports car, what do you guys think? Also what is your opinions on K&N air intake systems?

I can't answer the exhaust ?'s. But the FIPK is a nice system, that would compliment any aftermarket exhaust.

BTW, welcome to the forum!!!

I just put a Volant intake on my truck, the increase in acceleration and power is great. There is also a cool sound around 2500-4000rpm's when accelerating hard. (a nice throaty sound, even without an exaust)

Which engine do you have in your truck?

I have a single in/dual out 40 series Flowmaster, and it's plenty loud, but not obnoxious (sp?). I don't really think I'd want any louder though. I also have a K&N FIPK and I'm really pleased with it. I can feel a little better throttle response with it.

I have the K&N FIPK and love it. I am planning on buying a Banks exhaust this summer.

Did the installs in three steps, driving the vehicle around a bit before going to the next one. My observations:

1- K&N FIPK-Increase in noise from engine compartment. Other thatn that, nothing to get excited about for a couple of hundred bucks.

2-JBA shorty headers- More noise from engine compartment. Again nothing to get excited about, especially for a couple of hundred bucks.

3-Cat back exhaust- More noise and in cab resonance. Slight loss in low end power due to lack of back pressure. Better rev capability on high end due to less restriction in the exhaust.

4-Replace cat back exhaust with another brand. Much better lowend and highend. AND a little less noise.

If I had to do it all over again, I would get a supercharger and save myself on all the noise.

Ditto, I'm running the same combo as tom (hmmm, looks like we're the same again) and it sounds great, but not loud at all w/ the windows up. From the outside it's nice and loud.

Mines the same as Tom and Jon's. I didn't notice any performance gains but the sound gets a lot of compliments, even from the emissions inspector.

its the 5.3L. I always thought that an aftermarket exhaust would increase low end, not decrease it?? I was also thinking of buying the K&N air intake system and JBA headers for performance and gas mileage gains. Right now stock my truck averages about 15.0 MPG. What are you guys getting after all the mods?

I don't even check my milage anymore. I just fill up every two weeks, or so.

That last time I DID check it was on a long, mostly intersate, trip, and I think it was 18-19 MPG. That was driving only slightly over the posted speed limits.

about 15 mpg rural/highway

I really like the Corsa cat-back exhaust and mate it with a upd air induction..This would be another option for you. The corsa tips are sweet and high quality.. I had the FIPK but like the UPD better after trying both..

WEFs99 · March 20, 2002

Redhawk...how does the Corsa sound on the truck? On the '02 Vette they are 'relatively' muffled just pokin around but a nice rap at WOT. The Flowmaster on my present 5.3 has more of a 1960's sound. I like them both.
