i was thinking about gettin opel injectors n a pcm, dp and catback from zzp er other brands for the exhaust. which ones the best sounding? im plannin on doin some stuff to the car n figure i should start with the bolt on stuff :P
soo what dp catted or catless
and what catback? needs to have a muffler cuz cops in ny are dicks but the resonators optional lol

zzp, turbo xs, ottp, they all have great exhaust products for the LNF. i have a turbo xs catless dp paired with a turbo xs rfl exhaust thats basically a straight pipe. the also offer the GT and FL exhaust. gt has a muffler and sounds great and the FL is louder but where the muffler is, they put a resonator. ZZP offers good exhausts and so does MPX. i know a lot of guys who are happy with their MPX as well.

I really like my MPx exhaust, it's relatively loud with a catless dp (mines zzp), little quieter with a high flow, and not bad with the stock dp. Real difference is at cruise around 70-80 on the drone, stock dp very little, high flow quiet drone, catless there is def a drone not really loud but loud enough you can't really ignore it.

this is how id like it to sound lol i think ima do the zzp catless dp and the turboxs rfl
one other question did u guys get a zzp pcm to get rid of the codes for it? er did u guys tune the codes out urselves? cuz my plan was to do the exhaust get opel injectors n then gms1 sensors then get the pcm. is that what i should do? er do i take it somewhere n have someone tune it after all that

You can't run the Opels without getting tune for them. Well I guess you could but the car would run like ****. I tune my own so never had experience with zzp and their pcms. But i'm sure you can ask zzp to make the proper adjustments for the injectors, map sensors, and the Opels.

bahoodle

yea they ask if u have any of that stuff installed when u go to order the pcm. i was just wonderin if thats how i should start tryin to make my car have some power

Aren't stock injectors fine for stock turbo cars on 91?

I've got a Turbo XS catless pipe. Bought it used with fairly low mileage and it's been fine for the 100 000 miles.

Do you have emissions in your area? Also I like the hahn racecraft cat back exhaust I would say don't worry about opels and get map sensors and bolt on stuff charge pipes intercooler downpipe cat back map sensors intake tube

bahoodle

i do :/ n idk what all i should get im kinda lookin for input on it lol if u guys think injectors are unecessary then i wont get em i just want as much cheap power as i can get cuz im 20 n have a terrible job lol

if you're only running 91 or 93 and don't have access to e85 or ever want to run it, leave the injectors stock

Here's my car. This was a video I recorded 3 years ago. But it still sounds the same.

You don't need injectors, it's not like an lsj car. If you are on a budget stay with the stock charge pipes, get a zzp intercooler and downpipe, leave the rest of the exhaust alone and get a good tune on it. Done.

Of all the videos iv seen Hahn hands down sounds the best. Even better in person.

cluelessk

their exhaust built better than their charge pipes?

bahoodle

u guys all have catless downpipes right? what did u do to not have a cel? did u get one wit angled o2 bung/ get an extender er did u do something on the cars tune so it doesnt have lean/ catalyst codes? thats like the last question i have n thanks for all ur guys's suggestions i really appreciate it!! i am a noob but in time i will still be a noob but with boltons...... lol

i know with the Turbo XS catless DP they welded and angled bung on theirs to not throw a code and ive had mine on for 6 years and never once threw a code

Tdubbs

I haven't had a CEL yet for my catless, and it has an angled bung for the o2 on it. You should be good as long as it pushes the sensor away from the pipe a bit.

Although I do have to brag and say my downpipe is infinitely better than any of the offerings on the market. Thanks again Omiotek

i never got a cel with the catless zzp downpipe+angled bung. didn't need an extender.

cluelessk

Have an extended bung. O2 still went bad.

-Catless DP
-ZZP intake tube w/ K&N drop in filter
-tune

Call it a day. Will be reliable and fun.

cluelessk

I'd personally go catted next time and recommend an AEM filter over the K&N. Still washable but doesn't require oil.

b9k

I would do at least the hotside charge pipe too or plan to do it later. My stock one looked brand spanking new before the tune, a week after tune with very mild use I saw heat stress and was discoloured on top. I still used it for awhile but was pretty obvious it wouldn't last.

zeeky420

I recommend zzp intake tube k&n drop in charge pipes upper and lower intercooler 3bar maps cat back and depending on emissions I would do a catted or catless downpipe and a good tune then later if you want to just upgrade turbo

My factory pipes look great. I keep my protected with a coating though

I actually might change to catted. The stinky cold starts annoy me sometimes
