I was just wandering if anyone has heard flowmasters on any rx7? I'd like to get a header and just run a straight pipe to the dual flowmasters, since they cancel sound frequencies for legal reasons but still give you decent horsepower. Give me your opinions thanks..

they supposidly sound like crap and wont hold up

Flowmaster themselves say not for use on rotaries

ok, what mufflers do hold up that aren't extremely loud or exspensive.

depends on your definition of loud, or expensive

i wanted to go with magnaflow for my car, but i dunno...

loud being the usual crackle of a straight through rotary with a header...i just want to tone it down a little. And exspensive being like under 300 for a cat back system.

the dynomax system might be a good bet for under $300

corksport is 300, but its loud

I too was wondering about something like this.



I'd like to have a custom catback made, ending with an Apexi N1 fart cannon, but I want something quiter.



I was wondering about a flowmaster, but if they burn out on rotaries, then no thanks...



Any advice on a resinator and high flow cat combo to keep it quiet?

racing beat is louder, but not that loud...

BORLA mufflers fukin own, and in the nopistons store there is a 2nd gen cat back all stainless steel for 370. 1 million mile warranty. That is a solid setup for cheap considering two borla mufflers would cost you that much alone.



and don't do the corksport cat back if your n/a. You WILL be arrested. I had that setup but refused to drive anywhere with it.

thats alot more money then $300

I second the thing about Flowmasters being incompatible for use on a rotary motor. I knew a guy that worked for Flowmaster for a while and he said that the only automobile Flowmasters were not supposed to go on were automobiles with rotary engines. Something about the mufflers creating too much back pressure.

You got the borlas? How do they sound?

Flowmasters DO NOT work, trust me!!!



I removed and installed a cheapo magnaflow, works great

I vote for Borla. They can take the heat. Not too loud on my T2, but I'm sure it'll be louder on an n/a with headers.

borla too

so where can i get borlas. And more importantly where can i get borla's cheap...

How loud are is the N1? Are they dual or are they single?

They are loud with out the silencers on. With the silencers on i'm almost stock sounding.

ok.. i like them a lot.. so i am thinking of a header, run to the stock cat (for state emmisions reasons and sound) to the n1 out would that sound good or would it be loud or sound like **** or what? The reason i have so many questions is because im the only one i know around here with an rx so i dont know what different mufflers sound like.

banzai how does that magnaflow sound? did it last awhile? im thinking about going with a rb header to straight pipes to magnaflow mufflers...

i got dual magnaflows ( one that look like n1's) and a piece of **** pacesetter header that is good for a little exhaust leak..... its loud as phuck though.. scared driving around tampa on saturday nights....i strongly suggest silencers for this type of mufflers.

i have magnaflows on my jeep, they are quiet at idle and

wake up midrange, not sure how they would sound

on a rotary though.



I have heard the full borla system with a single stock

style converter, and the car was very quiet.



RB sounds the best, I have Borla XR1s on my car, and they

are quite loud.

i got racing beat



i love it



not that loud, but turbo's aren't that loud anyway

I've got the Borla setip, and I love it. I had a Flowmaster setup before this, and the sounded like crap, and they flaked away on me. But the Borla setup gave me a decent power gain that I could fell when I jumped on it, and they are quiet, but deep, at idle and normal shifting around town, but when you get on it, they get loud and deep. You should deffinatly go with the Borla catback exhaust. My only regret about this system though, is that I wish I had waited because I paid 500.00, and now they go for 375.00ish. But I will try and get a sound clip up.

I don't have the borla cat back, but from every borla muffler I have heard it has sounded good, not to mention that it will last. That is what they are usinging on the racing rx8's if that gives you any idea.



I'd like to grab that setup, but I'm buying a house and fixing two cars at this time so it's not pheasable.

Does anybody know how loud the GReddy cat backs are on a n/a and a strait system and aftermarket headers and even the Apexi dual N1s? If u have that setup how well do they run and whats the aprox life?

Thanks a lot

Cort

just thought I'd thrown my setup in here



I had an RB header and presilencer, with stock catback. No louder than your average ricer, but really rattly and buzzy. From the presilencer back, I just had 2.5" pipe with 1 magnaflow straight-through muffler put on. Sounds no louder, but a more mellowed tone, more low and less buzz.

I had them on my 1979 rx7 with header way back in the day ( 1991) and they worked fine for years in fact the muffler is still around on another car. Why would'nt they last there is no packing in them.

I said supposidly, and if flowmaster themselves said not to use

them I would just take thier advice.



they are baffled mufflers, so I guess there is potential for problems

there. Maybe they are worried that from the high heat there is the

potential for one of the baffles to break free blocking the muffler's

output. Email flowmaster and maybe they can give the full story?

there were flowmasters on a NA I picked up in north carolina, it sounded like ass but they werent falling apart.



it had stock manifold and a cat then two flowmasters, sounded like a weed wacker. I suspect if it had no cat and a better exhaust system overall the flowmasters would have been getting alot more abuse, but the system was really ghetto. The Y section was more like a T.

we must have typed at the same time?

Here is a pic of the setup on the car. If it makes a difference to you.

And another

I would deffinately reccomend this setup to anyone who is looking for a quality cat back exhaust system.

gotten a chance to make a video of it?

does anyone with n1 duals have a picture of there setups??

I really dont know how to take the video and patch it into the computer, it someone could help/tell me how to do it, I could try.

my cousin has a 1 into 2 flowmaster on his 7 and it sounds like an indy car. at first its cool but gets annoying
