hey guys new to this forum, just wondering if a 3inch going into 3.5inch exhaust is going to be too big for my s15.its only $100 and seems to be in good nick, my car is stock but am doin pod filter, exhaust and basic mods. Turbo S14 Silvia aftermarket exhaust system for sale - TradeMe.co.nz - New Zealand Will this exhaust be too loud and not have enough back pressure? thanks for any advice

yea bro it pretty big piping for stock s15 but if u upgrade push more power should be good i would get it personally good price looks clean as for the back pressure it should be good but the three inch is best for sr

swt i hit the buy now on it i thought for $100 cant got too wrong, and its gotta be better than the stock exhaust!

Turbo cars do best with zero backpressure in the exhaust, so...3" is just kind of a standard minimum size. Anything bigger may be overkill but absolutely will not hurt performance. It may be a bit louder that's all depending on muffler size.

100.00 go for it u might loose a small amount of power but doubt u will notice it. but the exhuast will come in handy as u do more upgraded where did u find this deal if u dont mind sharing

a turbo car would run good and make the most power with only a downpipe..
the turbo creates all the back pressure it needs..
so yeah, the bigger the pipe the better.
plus this gives you a open door to upgrades.
you will never ever have to change it as far as proformance goes.
like stated above it may be loud.. look into a good muffler and a resonator..

hey thanks for all the advice guys, so..... i had the exhaust fitted today, didnt take too many mods to make it fit the guy did a great job and only $130 labour...Anyways the performance, well what can i say its like driving a different car! it ihas increased from factory 7lb(nz import 200sx) to 12lb just by adding the pod filter and exhaust!! Im very happy with my $280 spent. Its got 265s on the rear and skids up jus by flooring it on most surfaces lol. Its loud but dont think its "ridiculously " loud.Very happy with the upgrade
