Exhausts

[vti-r teg]

I have a 97 vtir and i'm going to do an exhaust but i'm confused about what to do.
I want to do headers and exhaust but I don't want it too much louder than it is now. Ihave been told to do just headers, hi-flow cat and leave the rest stock.
does anyone know how effective this would be for power gain/ would doing the rest of the system make that much of a difference?

[sugapopcandy]

doing the whole system would definately give you more gains.. but then it depends on what exhaust you are getting.. [?]

[kramcivic]

twin loop is the quitest as we all heard....

[JINRAI]

search or ban :p

[nipnip]

cat back alone will not get you good gains, just noise

header and cat with stock exhaust is more effective then just a cat back. i think ppl were suggesting you start with cat and headers

4 - 1 headers
Hi flow Cat
2.25 inch full zorst system

Cat back system will only produce noise - not more power. (we need a dyno print out to prove otherwise!).
Being the cheaper option and also portrays a mental image ( more noise = more "speed feel") you are probably best getting a hi-flow cat and cat-back piping.

Add another $500-$1500 for a header...remember this is where you will free up the most flow + horsepower ! ( and a decent header is a pre-requisite *spl?* for more mods later on.)

I'm about to get a Toda Header (Thankx Adrian), JDM Cat & Vision 'B' Pipe ( thur Leonardy - JDM Concepts). Should be quite a weight difference.
Now I have to figure out which Axle back to get...Ideas? Twin loop mugen would be nice & not be too loud at the sametime.

[LatinoHatchCrap]

Just getting one part (ie headers) and leaving it as is might only create noise and bottlenecks.

Mugen Twin loop cat back will do the job...
I would personally leave the headers stock useless your willing to spend thousands

[quangsta]

With a zorst system right....if i was to get a new header would that still without the cat would that sitll fit my stock pipe??...coz i always thought the piping had to be the same size all the way so in order for me to change any part of my zorst i would have to change the whole thing....if im wrong could i just buy a header and upgrade my cat and zorst later??

u may wish to start looking at known quiet/silent mufflers such as the twin loop. most noise and drone will come from ur muffler, also resonators.
more muffling and more resonators may also equal more restrictions

[franki]

yeh u can do that. im just afraid that if i do the zorst itl sound like crap. i cant stand that tinee sound. :honda:

I've been told that a stock type r system is one of the best to put on a vti-r.
n e one able to shed some light on this theory?

i had about four dyno sheets that showed gains from 3000-8000rpm from changing my cat back and various bits. in changing from a 2" press bent stock system to a 2.5" mandrel bent system you can expect to feel a substantial difference. if my memory serves me correctly, i first dyno'd with 82kw at c&v, then pulled 89 with a "hurricane" header -which is supposedly no better than stock- and a 2.25" mandrel bent exhaust. i went back there again with a 2.5" cat back a month later and pulled 92kw. there was a very slight dip in power in the bottom end from changing to the 2.5".
