Guest polarity Posted October 23, 2002 Share Posted October 23, 2002 my brother just bought an 89 GTU Rx-7. Right now he is looking at upgrading the exhaust. So far everything he has read points him to a cat back exhaust system (running around $600 for parts alone) Anyone used something else and have good things to say about them?

Guest livewire23 Posted October 23, 2002 Share Posted October 23, 2002 this post is a bit off topic no? anyway, I've never heard of anything but true cat-back exhaust systems giving any kind of real performance gain. The alternatives are a muffler, or a muffler tip, but all those do is change the exhaust note of the car. Quote Link to comment Share on other sites More sharing options...
Guest GoaTSLonG Posted October 23, 2002 Share Posted October 23, 2002 im getting my 87 rx7 GXL on saturday but i have heard that running straight pipes to some good muffles give a little performace gain and is fairly cheap (around $300) also check out apexi's N1 exaust system Quote Link to comment Share on other sites More sharing options...
Guest shortyz Posted October 23, 2002 Share Posted October 23, 2002 spend your money on a new header. like a DC performance header. they are like 350$ then work on the exhaust from the header back Quote Link to comment Share on other sites More sharing options...
383 240z Posted October 24, 2002 Share Posted October 24, 2002 Please dont wast your money on a $600 dollar system A good exhaust that will live in the firey hell of a hard running rotory check out the systems for sale at www.mazdatrix.com and www.racingbeat.com but first you will have to answer a few serious q's How loud can I live with? Will I need to pass emissions. is this a STREET car or a RACE car? A good full length exhaust will run about $1200 but will really wake the car up I have been dealing with racing beat for a long time and have had NOTHING but positive expereinces with them when I went to MSA in 2001 I stopped by there shop they were FIRST RATE gave me a full tour of the R&D center and answered a TON of tech questions Keith Quote Link to comment Share on other sites More sharing options...
