so im looking to get an exhaust for my car, nothing crazy, over all i just want a deeper louder tone and maybe like a 5-10 hp gain lol. but can i just buy universal mufflers off ebay and get them welded on? or should i save and get some HKS universals? and does it really matter or am i just paying for the name with an HKS exhaust?

somthing like this maybe?

First off, you are probably not going to be gaining any noticeable power increases. Are you planning on just getting the mufflers put on or are you having a shop build the entire system? I have never tried eBay mufflers, so this is just based on my opinion. The money that is spent on an authentic exhaust goes into the sound/tonal qualities, R&D and craftsmanship of the company.

If you have heard an 4" HKS Ti (not Carbon Ti) on a boosted 2J, you will know exactly what mean. It's got a great sound.

 

i have a ebay exhaust(full 3") system. and i mean full. i got it from cx racing. sounds great. that throaty feel. i gained some hp(because iam turbo). an n/a not sure if youre going to gain anything. depending whats inside the exhaust(the materials in the tube). it will sound like a honda fart can. or it will sound decent.

 

I got some OBX Apex-I WSII want to be... and got the 3" all the way back. It's not super loud but it is loud due to the fact it's 3" and non turbo yet. They don't sound bad they do the job.

 

1 u wont get any power behind this just a louder db voulume.

2. if u want power out of ur n/a u need heards intake cams itb u know (the usual)

3 if dont the right way just get a nice axel back and be done with it

 

I have an ebay universal muffler, very similar to the one you posted there, and I like it. Very smooth tone at idle, 3'' inlet, 4.5'' out. Although I am waiting to finish up my 5'' for later in the build with a different exhaust, I like the ebay muffler I have.

BUT, quality in overall craftsmanship between ebay and say an HKS/Greddy, its almost night/day difference. The packing material, quality of the metal, welds(thickness and weld type) is going to be much better with a higher end exhaust. But unless your going for bragging rights, there really isnt a major gain. All these mufflers advertising 10-25+ rwhp increase, regardless of manufacturer, are full of BS. If you want power gains, just turbo and run straight pipe.

 

That muffler costs more than my entire 3'' turbo back exhaust..DP, MP, mandrel bends, and the muffler...

 

the best bank for your buck imo is the apexi n1 universal mufflers i picked up 2 for $100 off of k2motor i think they sound great for being na not raspy but quite at idle but sound nice with wot

.I have these ebay mufflers on my car. but I am turbo with a 3" exhaust with no cat into dual 2.5". its pretty loud but not ricey sounding. I noticed a difference over the factory supra exhaust that was on the car

 

cut out the factory mufflers and weld in a summit resonator.

 

im interested in doing mine from the cat back in 3 1/2 single exit, Not sure of what it will sound like because im still NA,If it sounds raspy il just trow a resonator at it and hope for the best

 

what size is the stock pipiing for sc400's? is it 2.5 or sumting like that

 

I wouldnt recommend 3.5'' for n/a unless you plan on boosting right away. 3'' is the biggest I would go for n/a.

 

sooner or later im gonna put some boost in it <i was under the car and noticed that the stock piping is about 3" already (at mid pipe) i just figured if i upped the size it would be better nut i do agree with you tho.

 

the size is 2.25"
