raffa_mk Posted May 18, 2011 Share Posted May 18, 2011 Since returning from japfest the baffles decided to go in my zhorst box which i really like, i dont know what make it was but it was from a gt, i currently have a cobra sport back box lying around and is massive (4" tip?) which can replace it and be welded on for the time being, however i am looking to get a full system cat back, i would like to know which system people have fitted and what sort of price have they paid and what difference you have noticed, I currently have glanza inlet mani with TB and will soon be followed by corralla exhaust mani with 2 runners from it to the system once Chris (nastyrash) has the kit to do it. I will be looking to get a 2" mid section as that's what most people are going for on the n/a's but i dont know which back box to get? i also dont know if i should get the back box angled? possibly a few pic's from other members will help Quote Link to post Share on other sites
Ryan5793 Posted May 18, 2011 Share Posted May 18, 2011 I've got a custom mid section from chanelle's old glanza rep with a decat on my n/a. needless to say its bloody loud! Got a HKS backbox and it sits perfect in my opinion. Cant say I've noticed any difference in power but its a little quicker than dai's na starlet on here lol Quote Link to post Share on other sites
Amjad Posted May 18, 2011 Share Posted May 18, 2011 2" straight through with 3.5" tip angled, completely custom. Noticed a nice gain mid to top end power Quote Link to post Share on other sites
raffa_mk Posted May 18, 2011 Author Share Posted May 18, 2011 is the main power difference in the decat i take it?i currently only have the back box fitted to standard pipe, don't want to decat it due to m.o.t as its a 3 months away.is it easy to swith back and forth with the d-cat? bolt off and on?dont know weather i should go to exhaust UK which is near me, herd some exhausts were boj'd up? but of my 2 mates who had a bmw compact and ibiza done were sound?

raffa_mk Posted May 18, 2011 Author Share Posted May 18, 2011 Thanks for the pics amjad thats exactly what i am looking for on all angles. which backbox have you got there? Quote Link to post Share on other sites
Ryan5793 Posted May 18, 2011 Share Posted May 18, 2011 think amjads is bigger than mine but heres mine anyways lol Quote Link to post Share on other sites
Amjad Posted May 18, 2011 Share Posted May 18, 2011 No probs. It was a custom one made by a local exhaust shop, 3.5" tip jap can. It had a permanently silenced tip on the end but I had them weld on a straight tip instead Quote Link to post Share on other sites
raffa_mk Posted May 18, 2011 Author Share Posted May 18, 2011 thanks ryan for the pics too, once i get my glanza bump on with lip it will look like yours, what size tip is on yours? as i would go i a bit bigger to make it more flush Quote Link to post Share on other sites
LukeH Posted May 18, 2011 Share Posted May 18, 2011 I got my complete system installed a couple weeks ago, it consist of:5E OBX manifold 2" custom mid section with cat back and silencer (would of had decat but MOT is soon)and at the back a 2.5" tailpipe (too loud imo)Since putting it on there has been a shit load more low down torque. mid range and top end power doesnt seem to feel much of a gain.this is more than likley due to running a standard 4e TB on the FTE inlet mani.i have to get the FTE TPS to be able to instal the TB.By the sound of the above a Decat does make a fair difference, but like you i have a MOT coming up so it wasnt really a option at the moment Quote Link to post Share on other sites
dai_starletN/A Posted May 19, 2011 Share Posted May 19, 2011 well i got a custom catback to a TRD back box it sounds quite sweet and i noticed a better pick up in the revs. if MOT's didn't exist i would have mine de-cated but once i get my FTE mani fitted it would be even better ;) Quote Link to post Share on other sites
raffa_mk Posted June 2, 2011 Author Share Posted June 2, 2011 just been down to exhaust uk and been quoted £285 for cat back system mid pipe will be min 2.25" and any jap back box, however they are all cobra sport brand, and will prob go for 3.5" tip and have it anglejust wanted to know is 2.25 ok or shall i have it 2.5"? or down size to 2"?

ryan lang Posted June 2, 2011 Share Posted June 2, 2011 the decat isnt the difference maker in power, the last RR day proved that Quote Link to post Share on other sites
rob_bower Posted June 2, 2011 Share Posted June 2, 2011 Yea mine was down on power after decating much more drivable after putting the cat back in! Prob due to the change in the delivery of torque! But with the lack of experiment on the n/a it's all about trial and error!As for the original question mine is running a one of 4-2-1 mani with a custom stainless cat back which is 2" if I remember correcty with just a back box!

5T4R7ET N/A Posted June 3, 2011 Share Posted June 3, 2011 Raffa - A 2.25 system will be fine. 2.5 is too much for a n/a Quote Link to post Share on other sites
