carguyinok Posted August 26, 2003 Share #2 Posted August 26, 2003 You may want to try a exhaust tip. They can change the note without going with a whole new muffler set-up. I am not sure of the name but there are a few packed much like a glass packs and they can take away alot of what you dont like for little money\work.

1975yellowBSPZ Posted August 26, 2003 Share #3 Posted August 26, 2003 I'd put a supertrapp tip on the rear, and leave the thrush on. It will take the harshness out and allow you to tune the note. This is what I plan to do, I have a 2 chamber flowmaster and I'm in the same boat as you.the supertrapp tips are like $70.BW Link to comment https://www.classiczcars.com/topic/7639-i-sound-like-a-biplane/#findComment-47853 Share on other sites More sharing options...

Plus there able to be tuned by the number of disc's you put in or pull out.

240Zdragon72 Posted August 26, 2003 Share #7 Posted August 26, 2003 Hey, Nutxo,what type is your engine? L24, L28? FI or SU Carbs?I also have been thinking of buying some Trapp's. My car is a '72 240Z with the L28 from a '83 280ZX.(Carbs) On top of being such a powerful engine is such a light car, I can't get her to even run. She'll crank but no fuel. I'm trying to trace the power wire back from the fuel pump because there is no power getting to it. I have been thinking of making a switch panel inside the car for the pump if I can't figure out the problem. Any suggestions?Thanks,Brian:alien: Link to comment https://www.classiczcars.com/topic/7639-i-sound-like-a-biplane/#findComment-47862 Share on other sites More sharing options...
nutxo Posted August 26, 2003 Author Share #8 Posted August 26, 2003 L28 , fuel injected. Just talked to a friend that works the performance counter at my favorite local parts store (they have a counter for performance only parts) and he basically told me to get a 280z muffler, he says the supertrapp will sound like crap so Im prolly gonna do a universal since oem is 160 bux Link to comment https://www.classiczcars.com/topic/7639-i-sound-like-a-biplane/#findComment-47865 Share on other sites More sharing options...
nutxo Posted August 26, 2003 Author Share #9 Posted August 26, 2003 my book for my 76 shows a relay for the fuel pump, ya checked that yet? Link to comment https://www.classiczcars.com/topic/7639-i-sound-like-a-biplane/#findComment-47866 Share on other sites More sharing options...
240Zdragon72 Posted August 26, 2003 Share #10 Posted August 26, 2003 No, I think the guy who ouned it before me might have spliced the wire with another. No luck so far. Would that be going with the NA muffler of a Turbo?Brian:alien: Link to comment https://www.classiczcars.com/topic/7639-i-sound-like-a-biplane/#findComment-47867 Share on other sites More sharing options...
sblake01 Posted August 27, 2003 Share #11 Posted August 27, 2003 Try Summit Racing. They have a good assortment of mufflers including their own brand which are very good for the price. I have one on my 64 L320 and one on my 79 810. They aren't loud but you can hear them when you get on it. If memory serves me correctly they are only $14.75 each for a 2 1/4" or 2 1/2" center/offset which is what a Z uses.Stephen Blakeney1979 810 2dr1978 280Z coupe1964 L320 pickup Link to comment https://www.classiczcars.com/topic/7639-i-sound-like-a-biplane/#findComment-47873 Share on other sites More sharing options...
240Zdragon72 Posted August 31, 2003 Share #12 Posted August 31, 2003 I got tired of finding this wire, and put new ones going to a carbon fiber guarded switch. this solved the fuel problem. Now she starts but wont run unless I keep the key in the start position. :mad: She can be a pain, but that is why I love her. Nutxo, did you have any luck with you "biplane" problem? I'd try a "Ractive" or "Blitz" exhaust. Something that will give you the flow you need, but without taking away your backpressure.Brian Link to comment https://www.classiczcars.com/topic/7639-i-sound-like-a-biplane/#findComment-48181 Share on other sites More sharing options...
