    put on magnaflow mufflers still quiet?

    well I finally put down the cash for for some magnaflow mufflers and had them put on . Leave the shop and im like WTF Its still quiet I do notice a very low purr but i expected it to be louder. maybe its the clogged cat that they told me I have. My question is when I get the cat changed Should I remove the resonator or will just getting the cat fixed make it louder?

    What Cadillac ? That question drives the whole answer....The second "front" single thing is the muffler. The back 2 things are resonators. You have just upgraded to 3 mufflers. Do you have a FSM ? Look up the exhaust system specs and find out what's what. An aftermarket cat should run $200 - $300, installed, for a legal "high performance" model. What makes you think the OEM is clogged? Any cat codes ? Lousy gas mileage ? You could eliminate the primary muffler, but may find things a bit noisy and resonant afterwards. Just thoughts from past experiences.......

    It's usually referred to the other way. The first chamber, right behind the cat, is very small, and is a resonator. The two mufflers are mounted aft of the "rear axle", and are what the original poster changed out.

    A clogged converter could silence the exhaust, sure. But I would get a second opinion on whether or not the cat is really clogged.

    When I asked the same complaint ,they told me to get rid of the cat,mufflers and changing the exhaust tips to a louder ones .
    I don't think by cancelling the resonator itself would work

    Aftermarket exhaust tips resound louder to OEM ones .My '03 lade was also like that .Having installed the chrome tips ,it would growl much harder to my ears

    I don't think you'd see that much volume change from the tips alone. Removing the resonator will certainly have more of an effect than changing the tips will.

    Re: put on magnaflow mufflers still quiet?

    sorry for taking so long to get back on this the car is a 99 seville sls. Well I went and had the resonator removed and that made a big difference Im loving it. Yes there is a drone in the system but I can live with it sounds like a modded 350z but with a deeper rumble . yeah baby I can set off car alarms lol i like it but i got the resonator in the trunk just in case. I got a chance to drive my old car today (93 cprice cop car tru duals no cat 2 chamber flowmasters) and its still louder. got back in the caddy listened to the drone and its liveable compaired to the caprice which makes me sick sometimes.

    I personally dislike a drone in an exhaust system. When I am on the highway for 4 hours at a time, this gets extremely tiresome. I do however like a deep loud exhaust note on hard acceleration. The problem is how to have both.

    I have done exhausts on many many many vehicles over the years, and the exhaust note is only changed by tips if they have a baffle in them. 99% of the time they are strictly cosmetic.

    My 2 cents.

    No problem, you just have to have a thoroughly designed and engineered system (Corsa) that usually costs much more than just a set of mufflers. As with most things in life, you get what you pay for. Nothing wrong at all with putting on a set of mufflers, if you can life with the tradeoffs, even if they may be slight.
