Posted by daniel992gnt, Dec-14-03 10:56 AM
i am wondering if you were to put a flowmaster like 30 series of 50 on a 420A and get that sweet snap and lope sound (with cams) like a V8???

snap crackle and pop usually means you have after market aggressive cams or a box of rice crispies.

Trust me... you don't want to do it. We built a 2.5" cat back unresonated with a Flowaster 40 series. I have cams, higher compression and head work, with high flow cat, it pretty much does sounds like an old muscle car.

I put the Flowmaster on, and woke up people at idle. blipped the throttle and it sounded very angry. I wouldn't have made 5 miles before I got pulled over it was that loud.

With cams and no headwork and stock cat you might get by and not be oscene, but do NOT put on a Flowmaster without a resonator, they do very little to muffle sound. The added resonance a 2.5" pipe creates Steve thought it sounded like a stock car when I started it up.

I'll be redoing it with a difference choice of mufflers.

forget the V8 sound. be original. i recommend greddy evo or apexi n1. there are lots of deep, "non ricey" sounding exhaust you can get for your car. goodluck. :cheers

You can have an idle like mine.... It lopes like a v8.. but has the exhaust of a ricer.

Just get some very aggressive cams. You'll idle like shit, sound hella aggressive, and probably be a hair faster.

While you're at it, you might want to consider making your fuel mixture way too rich, so you can occaisionally backfire and shoot exhaust flames.

:D

I'm just messing with you, man.. Usually, the snap and crack you're referring to are just byproducts of aggressive tuning. I like the quiet/semi aggressive myself, so I haven't done too much to change the sound of my car.

Try experimenting with different combinations of resonators and pipe diameters, if you're really die-hard about the perfect sound.

Your gonna need a straight through exaust to shoot fire. I have no cat 2.5" pipe and a straight through resinator type muffler. It sounds great, the turbo helps the sound a lot.

When I use my stutter box I can hit a spot with the throttle that will make the EIC dump some extra fuel and get a backfire out of it. With my exaust setup it sends a little fire out the muffler, kinda cool. Between the stutter box and the flaming exaust the ricers seem to stay away from me, which is a bonus.
