Looking into modding my exhaust. Bbk short ceramic headers, h pipe, with borla s type axleback. I'm looking for a deep non raspy tone thats not too over the top has anyone done this set up?
What H-Pipe? Since anything that removes the stock cats and resonators creates drone and rasp.
Mine is BBK short tubes, FRPP cut and Clamp X Pipe and Borla Touring. No Rasp no Drone.
I'm not sure if I can find an h pipe for v6 2012. X pipe is raspy with borla s type and short tube bbks around 3500 Rpm. But even with an x pipe with upgraded resonators it will possibly fix any rasp I am hearing on YouTube.
I've had these cats for 130k miles so I'm sure they need replaced either way.
Like I said, you go aftermarket you get rasp, then after you get rasp you end up putting more money into it to get it to do the job the stock does. Mine are stock, the cut and clamp X goes on after the Resonators and no Rasp.
I don't think the cats ever need to be replaced unless there is some major unusual failure; pretty sure they do not wear out . . . personally i would not remove the cats because I would not want the hassle with emissions inspection and it won't add much performance if any, mostly just makes it loud (and obnoxious depending on your tastes)
There's no emissions tests in my state. Just every state around me.
The shop I was going to said my cars could be clogged or dirty causing me to get this occasional o2 sensor code. I did run cataclean in my system yesterday and I have a bottle of red line fuel system cleaner I plan to run after this tank of gas.

ok, to start with...get away from that shop...…. 1) unless they did a flow/pressure drop test there is no way they could even remotely state that is a potential issue generating the problem...……. 2) Even if you don't have emissions testing, federal law prohibits touching those cats unless you exceed 8 years of age or 80k miles....the mfg has to replace them if they have failed (for free)….. 3) installing "high flow' cats (which i'm sure is what they are also going to recommend...is complete BS...as there is no such thing....just cheaply made cats that will fail sooner than you would like.... and IMHO, don't give any law enforcement officer any opportunity (if they are having a bad day) to impound your car..... installing louder mufflers...sure....messing with the cats......the leo will have probable cause to further investigate and if they see the cats have been messed with...say hello to an impound.... and a court date and an inspection.
Let's talk just for a bit on the H versus X pipe..... The H-Pipe really plays very littlein terms of performance- nor does it reduce backpressure in any way- it wasoriginally introduced to equalize the pressure between the two pipes, inducinga scavenging effect, but in reality, while it did improve some things a little,all it really, the only thing it really was effective at was to reduce noise-nothing more. An X-pipe will increase HP if itis installed at the "area of confusion"- but that area is identifiedby painting a small strip on the exhaust pipes about 1/2 way between the engineand the axle- the area of confusion will cause increased heat and blister/burnthe paint at that location- that's where the H or X pipe would be installed-and eliminates the air flow disturbance by sending alternating pulses in thatlocation which acts as a "vacuum" if you will to push & scavengethe remaining and incoming air out.
You can spend any amount of $ you want on a muffler but, I would recommend saving a lot ofmoney & go with Allied resonators......available is any muffler shopnationwide, are of excellent quality, 1/2 the price of “performance Mufflers”, availablein any length from 10" to 38" (IIRR), flow as good as Borla or mostany of the "Race Mufflers”, tone is deeper and you get a nice rumble (low)with no drone and none of the tinny "ricer" echo or crappy "brap". Allied has beenmade for at least 30 years and available in just about any diameter you wouldrequire (I have personally run these for since the 1970's....nice low rumble onacceleration & deceloration, no drone, deep tone.
Any good muffler shop should be more than willing to drop your mufflers, hold up different size/type of mufflers to fit the sound you want...… if they won't...walk away to another shop!!!!!!!!!!!!!!!
I agree - don't mess with the catalytic converters. That being said I recently replaced my mid pipes with Borla's to get rid of the resonators and increase the loudness of my exhaust a little.......and it did VERY little. I was mainly concerned looking at the stock pipes about the kinked areas and I wanted to remove any possible restriction. The stock resonators are a straight through design and are NOT a restriction. THey are perforated to an outer shell which has a flat area, but I cut open my mid pipes just to confirm they were not restricting flow. But I don't see their removal making a big difference in sound level or quality. If you want that, change your axle back mufflers instead. You can go mild to wild depending on preference regardless of the resonator pipes. As for drone, I can say for sure that I have no drone with my Corsa axle backs, either before and after the resonator removal. And you can't really trust the you tube sound bytes as I have found none of the exhausts really sound good on video. Go to a Mustang meet and hear them in person if you want to know how they really sound.
I have Kooks long tube headers, cats, H pipe and 2011 GT 500 mufflers. My car certainly doesn't sound like one of the thousand Borlas on the street. It's noisy! I love the sound and some of my neighbors hate the sound. It's great to be an individual, especially when one is letting off of the gas pedal in 2nd gear:grin:
My recommendation to you.... Be an individual and find an exhaust note that fits your personality (lots of exhaust notes on you tube) ... Oh yes... CATS are important for the environment!
