Exaust questions

[Scott82]

I have been looking on ebay at performance mufflers and i was wondering if anyone had any experience with any of these mufflers on ebay. Some of the prices are drastically low and was wondering if anyone has tried anything exaust wise cat, muffler, header. If so, how happy are you with the results nd does it matter which muffler i get if i am making my own exaust as long as it is a 4 cly performance muffler and what not?

they are cheap mufflers so they will sound good for the first hour then they will get all raspy. if you want a good deep sound, get a name brand like greddy or thermal

[Scott82]

Where can i get the best deals on name brand mufflers and exaust parts. and is the raspyness with just the muffler or cat and headers too?

[Scott82]

just a quick Q whats the team lonely drivers about? it took me to a search engine.

i have had an obx 4-2-1 stainless 2 piece header and high flow cat for about 5k miles and so far so good

i had one of those ebay fireball mufflers that i got for 30 bucks when i had my old mazda. surprisingly, it sounded better then alot of others that i've heard and didn't sound raspy at all. maybe i just got lucky.

Also, what is the difference from 4-2-1 and 4-1 in Hp or performance. Is one better than the other?

From what ive read a 4-2-1 is better on a sohc and 4-1 is better on a dohc. anyone else heard this? correct me if im wrong

[Scott82]

Is more back pressure good for the sohc cause of the low end torque that it has?

[civickiller]

raspy sound usually come from the muffler or a lack of a cat.

a 4-2-1 is made for more lower and mid range tq, 4-1 is made for more top end power. dohc vtec motors are good motors for the 4-1 header.

i always say the more free flowing the better. gives your more hp but they say you lose alittle down low tq.

backpressure is a trickey subject some people think none is best some think you need some, personally i think you will need some backpressure. if you do a search i think there was a thread about this a few months ago also they have talked about it on homemadeturbo.com you may even want to google it to find articles i,d find em but right now im tired

I heard the sohc has good low end torque so should i stick with the 4-2-1 with high flow cat from ebay and a name brand muffler?

not too sure you want to call it good low end torque but for what youre doing a 4-2-1 header high flow cat and custom exhaust should be fine. Thats what im doing to my car. BTW hope you dont have to pass emissions because the ebay high flow cats might as well be a test pipe.

[Scott82]

no emissions to worry about!!!! should i just run a straight pipe instead of a cat? and what do i do with my 02 sensor if thats the case?
