I have a 88 non turbo rx-7. the only modification i have is a K&N intake, but i plan on buying a high flow cat from RX-7.com and having a muffler shop in my town build the rest. any suggestions for a quiet reliable muffler. also does anyone know if those moroso spiral mufflers are any good.

i have heard racing beats muffler and there very nice but there 220 a piece. im looking for something cheaper

im preety sure that if you want both quiet and reliable then cheap isnt really one of your options... i would take a look at rx7.com and mazdatrix.com and see if they have anything in your price range

im preety sure that you have to get a muffler designed to handle the heat of the rx7 exaust or its gonna die quick (i dunno from experience, just what i read)

Get a Sportsman XL spintech muffler, it is supposed to be there quitest muffler, and they are very good quality mufflers, and create very little if any back pressure. But 1 muffler ( that is all you should need ) is $120+shipping. But you would either have to make it a single or put the muffler in the middle of the car.

remember the 7's exhaust is very very hot, so u need to get something that can handle the heat!!

i'd get the MT racing beat single system, but the muffler tips on RB's website just look buttass ugly.

I have a set of Aero Speed mufflers FS, they are pretty quit and look pretty good.

Quiet mufflers are for ******. 2cents

Here is your rundown:

Cheap= low quality
Cheap= low lifespan
Quality= cost
Quality= better sound
Quality= longer life


Even the mufflers that Cory pointed out are still expensive. I would get the RB cat-back and be done with it knowing that I won't need mufflers for atleast several years. Those cheap mufflers will die quick. Maybe a year or two. The RB mufflers have been quoted as high on the quiet scale if not the highest on that scale. I have them on my car and they are nice. Although they let people know you are there when you are on it.

You get what you pay for. So I recommend you don't get some 40 dollar mufflers.

Which one's, the Aeor Speed, or the Spintech's.

If you mean the AeroSpeed, those are mine, and I will sell the for $150+shipping (there are two)

Cory Simpson

Do you mean me, and which exhaust???

Lazy-Rx7

a magnaflow would probably be your best bet. steel wool packing to resist temps and a straight through design. try hottexhaust.com

i just lobbed off the cats today, so now all i have on the exhaust system is 2 stock mufflers.

NOT fun.

well its kinda fun

but the problem is the stock mufflers are really being torn apart FAST without the cats.. i knew it would happen, but this fast! im totally shocked!

Steel wool packing along with glass packs will have the packing blown out of them after a while, or so every one says.

But I still think that the strongest muffler out there is the Spin Tech's. There are hand made out of 304 gauge steel, and mine have out lasted most peoples bets. Or at least the people that said they would blow up after 1 day. And the haeders have changed color (didn't take long) and there is still no problem.

Cory Simpson

Well that means I'm about as far away from a ***** as I can get.

haha.. i guess that means all the teg/civ ricers are cool and got huge manly ***** cause they got gigantic 6" tipped fart cannons clamped to the stock exhaust, eh?

Magnaflows make the car sound like a truck or something. I can't describe it really but my friend has them on and I personaly don't like it. it is kinda quiet though.

My friend has some magnaflow mufflers that he got off of ebay and they have a huge tip robably like 4 or 5 inch I would guestimate. Don't get me wrong it is not a shitty sound but I like my Racing Beat mufflers a lot better than the magnaflows. Plus I beat him in a freeway run
