Glasspack exhaust for my 1.6?

[ctrench]

ok i basically have a stock motor 1.6 with a rebuilt head and port/polish, intake, and magnaflow muffler and im looking for opinions or experience on a custom exhaust

i want to trash everything from the header back and get 2.5" staight back with a 18" cherry bomb glasspack... i expect loud, but will it sound like crap?

it will drone like a bitch and give you headaches in the first month and you will want to rip it off your car.

Did this on my first miata and the sounds was kinda cool, but it was hell on my ears on the highway. Ended up taking it off and installing a HKS Super Drager cat-back instead, all the deep bass without the drones and nice bump in SOTP hp

i dont really care about the droning, i just want to know if it will be raspy or will it sound pretty good/deep?

[— Phatmiata —]

mine was pretty deep, only way you will know if you are gonna like it is to try it yourself I guess?

ok ill probably end up doing the 2.5" with a glasspack but anyone else have an opinion or experience?

header and standalone ECU will help you more than a straight thru with a reworked head.

There was a car at MATG with 2.5" exhaust and glasspack muffler. Sounded like crap IMO.

unfortunetly header and standalone arent in the budget at this moment, otherwise i would

Just an opinion here, stay with the 2.25" exhaust. 2.5" and a glasspack sounds like ass. You WILL attract the wrong kind of attention with that.

You can get a Raceland header for $160.

Or you can just put the turbo you have on, ignore the header with a downpipe and have tons of fun.

It will not drone, it will sound terrific. I had installed a good old fashioned cherry bomb glass pack on my last na and the thing got compliments everywhere it went, especially from other Miata enthusiasts. IT sounded very much like a carbureted, tuned, 60s vintage roadster . I forget what size it was but only one size will fit under there, I think it may have been a 16 inch. The rest of my exhaust was stock. IT was very loud at first and I thought I may have made a mistake as I pulled away but after a little while I got used to it and loved it. So too did just about everyone else that heard it. Gave me a bit of crackle and pop as well. I would definitely recommend it.

thanks for everyone's input... this picture explains my plan; red is muffler black is exhaust (no catalytic converter)

I cant speak to how it will sound without a cat. I dont remember if I kept mine or not, though I suspect I had ditched mine as well I am not 100% certain.

i currently have stock exhaust piping with my cat gutted and a magnaflow muffler and it has a little rasp to it, but sounds good... thats the main thing im concerned about i DO NOT want my car to sound ricey!!
